Yeah, there we go.

Okay, so we’re back.

I went away.

I forgot exactly what I told you before I cut the video, but I went away.

I recorded a different video where I installed the drivers for this Wi-Fi dongle.

I compiled them from source.

I found them on GitHub.

I wanted you to go to that video and use it to learn how to compile the drivers for your

own Wi-Fi dongle.

If you want to have the same dongle that I have, that video I should have a link to where

a link to where you can buy the same dongle that I have.

But if you have a different dongle, that’s okay.

The instructions in the other video should probably help you.

So at this point now, you’ve gone away to compile the drivers for your Wi-Fi

dongle and you’re back, you’re ready to continue making your Pi access point.

So what we should do is I’m logged into the Pi right now.

And let’s use Network Manager to see what’s up.

Let’s use network manager to see what’s up.

Network manager connections show.

We only have ethernet up right now.

We want to connect as a client to your existing router.

So remember we have two radios.

One is going to be the internal radio of the Pi or a dongle if you wanted to buy two dongles.

And then the other one is going to be the dongle that we’ve been talking about.

So I mean, I’m saying you can buy two dongles and stick them in the Pi if you want a little

bit more range.

For me, I just use the internal of the Pi and then the dongle as the external.

the external so the dongle is going to connect nowhere it’s just going to be an access point so

that other clients can connect to it so I’m going to connect as a client specifically using wireless

LAN zero because that’s the built-in ethernet sorry wireless adapter of the pie we can do this

in network manager we don’t even need a desktop we’ll say pseudo network manager device Wi-Fi

connect and then we just have to specify the name of your original or how about your primary

original or how about your primary access point you know whatever it is whatever your wi-fi

credentials are you got to put that there i’m not going to show you i’m going to type this into

another window so that you don’t have to see the name of my access point let me go sudo network

like that the name of the access point and then after that you have to put a couple more things

in so you’re going to do the interface name you should name which radio you want to do the

connecting as a client so I’m going to put WLAN zero because that’s what we just said if name

WLAN zero in the other window and then you want to provide the password for your wi-fi access

point so I’m just going to put password here your password here and then I’m going to type that for

And then I’m going to type that for myself up in the other window.

Oh, shit.

There we go.

Okay, I think that’s probably all we need right now.

I’m just going to hit enter on my other window.

You should hit enter now.

it’s saying that it does not see the network we forgot to turn the radio on the the wi-fi adapter

is off right now so that’s that’s a default thing with the raspberry pi so we’ll go into a tool

called raspy config raspy config raspy config um you could use a program called rf kill to activate

the radio but the raspberry config is more fun so what you want to do is uh after you say you know

sudo-rasby-config, you go into localization options, and you select the wireless LAN country.

So that’s, you know, because different countries have different regulations, they’ll restrict like

the frequency bands you can use or whatever. I’m not sure about all the countries, but I’m going

to find United States in the use. There’s only a few of us, only a few use. And now the Wi-Fi

idea, I go to advanced options and select expand file system. Because if you remember, I’m going

to do a reboot real fast. Yeah, if you recall, we, what’s going on, man, I want to ping.

We wrote a very small image to the card. It was only like two gigabytes or something, right? So

that means the file system is only two gigabytes, but the card is way bigger than that. And I want,

to be able to take advantage of all the space on the card so that’s why you expand the file system

and raspberry pi has like a nice little tool that helps you do that so it’s pinging again i should

be able to get in there okay uh going back to my other window real fast i’m just going to check that

the uh the connection actually worked so wireless lens zero oh it didn’t even work last time for

sure so we’re gonna we’re gonna repeat that command because the wi-fi wasn’t on before right so

the wi-fi wasn’t on before right so so if you recall uh we did sudo network manager device wi-fi

connect and then the name of your access point and then if name wireless land zero and then the

password i’m going to type that into my other window here and if we’re lucky it’ll connect

yeah okay it seems to uh have worked and then sudo and see what you should show okay

rename the connection real fast and then I’ll show it to you in the main terminal windows

so you do network manager connection edit main one and set the connection ID to how

about just like connect as client save quit show okay so now I think I can show you this

so it’ll pseudo network manager command line interface connections show and you can see

connected as a client to the rest of my network. At this point I could pull out the ethernet

adapter if I wanted to, but I still don’t like doing that because it’s pretty easy to lose your

connection and screw everything up and the ethernet is there to save you. But for now I have connected

as a client on wireless LAN zero. Make sure you have the right one selected. And if you did it

wrong you can do pseudo network manager connection delete and then just name the connection. But I

So let me just edit the IP address real fast.

Edit, connect as clients.

You’re probably gonna wanna do this

because remember we talked before

about the idea of you having IP addresses

that you had to come up with to follow this video.

So I’m going to, oh gosh, what’s happening?

There we go.

Let me go to this one.

Right, so I’m trying to set up wireless LAN 0 so it’s going to be 147 for me.

Maybe not the same thing for you.

So I’m going to go, let’s see, I just edited it.

Okay, so I’m going to set ipv4.addresses as that with a 24 block.

And yes, I want to set to manual.

I want to set the gateway.

Basically this is the same thing that we did with the ethernet already.

Then I’m going to set the DNS.

DNS, the only difference here between, you know, this connection and the ethernet connection

is I’m just setting a different IP address, but I’m giving it the same gateway and the

same DNS servers and everything.

So DNS search, home, I’m going to save it and then I’m going to quit it.

At this point you could reboot the Pi.

Maybe I should do that so I can read my notes a little bit more.

Let’s reboot the Pi and let’s see if we can connect on the wireless interface.

interface so I think it was 147 I just set up let me do a ping at 147 so I’ll

know if the Wi-Fi comes on I may have forgotten to tell it to auto connect

like I did last time but I feel like the Wi-Fi does that already we’ll see what

happens I’ll just give it like 10 more seconds yay it worked okay so now we’re

through the wi-fi notice how it says i don’t recognize this remote because it’s a different

ip address but we’re on the pi so now you’ve got two ways to get into your pi i’m actually going

to revert because i like staying on ethernet but uh just so you know this is how the pi will get

its internet after you eventually put this repeater somewhere where you can’t get ethernet you know

like in your garage or on top of a china hutch or whatever so um the next thing that we need to do

The next thing that we need to do is, um,

we need to install a program called DNS mask. We need a DHCP server because what’s,

what’s going to happen basically is when we connect it as a client to the primary router,

its DHCP server gave us an IP address on the normal subnet. So that’s fine. We don’t really

need that for the primary connection. But when we become an access point with the extra antenna,

connects to our pi as a client is going to need ip addresses and it’s not going to be able to get

the ip address the clients are not going to be able to get the ip address their ip addresses

from the router anymore because they’re not even connected to the router they’re connected to the

pi and there’s an isolation because there’s two different networks so that means we need to put

a dhcp server on the pi so the pi can just decide what ip addresses everybody has on its network so

I think what I’m going to do since the video is already about 15 minutes long into this particular segment

and I think the whole video is already like over an hour for sure

I’m going to pause the video and I’m going to go away and make another video

where I just talk about how to install DNS mask on your Raspberry Pi

so you should go to that other video and then come back

when you have a DNS mask all set up

and then maybe I’ll just copy paste the config

config that i’m actually using for this particular project just to make it more clear this is the

sample configuration file for dns mask it’s not too bad that that’s kind of it it’s kind of all

you have to do so uh i think i’m just going to install dns mask right now for you what i did a

moment ago is i said sudo apt install dns mask so it’s already installed for me and then to give it

called etc dns mask and any file you create in this dot d directory and this is kind of typical

for programs that recognize a dot d drop directory you can just stick configuration files in there

and they’ll be read automatically so this is the configuration i’m going to use for my dhcp server

on my pi you should probably use something similar but not exactly the same or not necessarily it

I’m using my search domain of home so you don’t have to do that because you don’t even you probably don’t even have the home domain unless you want one and then I’m gonna I’m gonna specify what IP addresses should get assigned to clients that connect to the access point.

the adapter this doesn’t work otherwise I guess it’s fine by default nobody’s

gonna be looking at this PI I don’t know maybe I should specify the adapter I’ll

make a note or I’ll come back in a second but anyway so we want to specify

an IP address range if you recall our IP address range that we chose for the

clients of the access point is going to be dot five dot something right so this

the subnet should match what we’ve chosen.

So all of the IPs that we give away should start with 192.168.5 and then something.

So notice out here I’m just saying 192.168.5.10.

So I’m saying that the first IP address that I will give away is a something.10.

And the last one that I’ll give away is a something.150.

I think most people don’t go up that high, but I just feel like it.

I want to go from 10 to 150.

and that gives me a little room to statically assign lower addresses if I really feel like it later or

High addresses if I feel like it later

This subnet right here. That’s the same thing as a slash 24 block

It just means only the last number should be able to change and then the least time 24 hours

That means if the if the PI

DHCP server gives an IP address to a client then that IP address should last for about 24 hours before the PI has to decide

decide um you know on another ip address or if it’s going to give it a longer lease or something

on the same one it’ll just it’ll just redetermine what’s going to happen uh then we’ll send a dhcp

option uh basically we’re going to tell the clients hey here’s the ip address of your gateway

so that’s called option three for dhcp options so we say three comma and then the dhcp server is

going to be dot five dot one at the end because that’s the number we’ve designated for wireless

for wireless LAN one, the gateway, you know, the wireless dongle that we’re setting up.

Then we’re going to send DNS servers.

You need DNS servers so that your clients can actually resolve names to addresses,

you know, like yahoo.com or google.com instead of their numbers.

So that’s going to be option six.

And then you basically just put every DNS server you know about,

or you want the clients to know about, separated by commas.

Just to point out also, we’re not covering IPv6 in this video

covering IPv6 in this video because we’re trying to keep it short but you probably want to continue

eventually and set up IPv6 on your own at some point but this will totally work without it

so my DNS servers are 1.101 but again you probably don’t have those as DNS servers

yours are probably just going to be the IP address of your router or maybe you can put in some public

DNS servers like 8.8.8.8 whatever you do write it all down there and save it

and before we try to run dns mask let’s watch messages and see what’s going on

actually you know what let me just type it and i won’t show you because there’s probably

sensitive stuff in there you use a command to watch service logs called journal control so

you’ll say pseudo journal control dash dash unit and then you just name the unit that you’re

interested in watching if you type if you press enter right now you’ll see all of the logs and

you’ll be able to scroll up and down, hit Q to exit.

But if you just wanna follow the logs in a live view

to see maybe problems as they’re occurring,

then you’ll do a dash F for follow.

I’m gonna do that in my other window right now,

just so that I can maybe catch myself

if something goes wrong.

So I’m gonna like copy paste this up here on a terminal.

Blup, blup, blup, blup, blup.

Okay.

So it says,

I think it actually just like reset itself once I change the config file.

That’s kind of cool.

So, but then the next steps you want to do just to be sure that this service is actually going to run for you.

You’ll say sudo system control status DNS mask.

And then it says it’s enabled on my system.

So then I’m going to do sudo system control enable dash dash now.

And that’ll just ensure that it’s enabled.

so it’ll start whenever the system boots and then it’ll start it right now also and every time you

change the configuration you probably want to do something like restart I actually I’m not sure you

need to do this because it looks like it was picking up the config while I was typing it and

saving it so pseudo apt sorry pseudo system control enable now and then restart and then

the DNS server should be running let’s see how much time do we have seven before I have to cut

So now we’re at the point where we have to set up IP forwarding because what’s going to happen is…

Actually, you know what? Let me do a scene cut because this is going to take more than seven minutes.

We’re almost there. We’re actually almost finished.

Well, not quite. We’re getting closer.

Okay, I’m going to do a scene cut.

Hey everybody. Thanks for watching this video again from the bottom of my heart. I really appreciate it.

really appreciate it. I do hope you did learn something and have some fun. If you could do me

a please, a small little favor, could you please subscribe and follow this channel or these videos

or whatever it is you do on the current social media website that you’re looking at right now.

It would really mean the world to me and it’ll help make more videos and grow this community.

So we’ll be able to do more videos, longer videos, better videos, or just I’ll be able to keep making

kindness and subscribe. You know sometimes I’m sleeping in the middle of the night and I just

wake up because I know somebody subscribed or followed. It just wakes me up and I get filled

with joy. That’s exactly what happens every single time. So you could do it as a nice favor to me or

you could troll me if you want to just wake me up in the middle of the night. Just subscribe

and then I’ll just wake up. I promise that’s what will happen. Also if you look at the middle of the

screen right now you should see a QR code which you can scan in order to go to the website which

which I think is also named somewhere at the bottom of this video and it’ll take you to my

main website where you can just kind of like see all the videos I published and the services and

tutorials and things that I offer and all that good stuff and if you have a suggestion for

clarifications or errata or just future videos that you want to see please leave a comment or

if you just want to say hey what’s up what’s going on you know just send me a comment whatever I also

in the middle of the night, I get, I wake up in a cold sweat and I’m like, it would really,

it really mean the world to me. I would really appreciate it. So again, thank you so much for

watching this video and enjoy the cool music as, as I fade into the darkness, which is coming for us

all.

Thank you.

Okay, I’m back.

I have finished writing my SD card.

I had a problem when the scene was paused.

Basically, those annoying pop-ups came back

where I was like in the middle of writing to the card

and the auto-mounting service suddenly decided

that there was a file system there

and it auto-mounted it and then it, you know,

put it up onto the screen.

And I think it corrupted the card.

So I ended up having to rewrite the card from scratch.

So let me just show you real fast within this video how to disable that service.

It’s sudo system control.

Start with status and then type uDiscs2.service.

For me, I already disabled this to get it working.

So what happened?

No, I already stopped it.

I already stopped it. Basically you just want to do stop to temporarily stop it.

And then if we go back to status, it’s still it’s still enabled. That just means that it’ll come back on for the next boot.

Okay, so if your SD card corrupted or anything like that, you probably want to start over after you disable U-Discs.

And then if we use the Partead partition editor again, we can see that SDB is still there.

So that’s still considered the name of our card. So now that

now that the auto-mounter is not doing anything for us we need to mount the card ourselves so

i’m going to go into cd actually just to double check media and then mike and then notice how

it’s not mounted so i’m going to go into cd i’m going to go into the temporary directory i’m going

to go into that pi directory i think i probably made that earlier on camera for you and then i

made two other directories one called boot and root so i’m just going to mount the uh oops dev

partition one, which is usually the boot partition to the boot folder.

Do my password and then do the same thing for partition two,

which is usually the file system root folder.

So first thing we need to do is go into the boot partition.

So this is what the pie will see when it boots up.

Yeah.

Okay.

So what we need to do is make an empty file called SSH in the boot folder

SSH in the boot folder or the boot partition because we want to tell the

pi that its SSH server should be enabled by default so I’m gonna go sudo touch

SSH if I list it again notice how there’s just an SSH folder and that’s it

there’s nothing inside of it the pi just knows the other thing we have to do is

modify the startup command line here I already did this actually when I jumped

Basically you want to do, you want to edit the cmdline.txt file, and then you want to

find the argument that says root wait.

And right after that, you want to stick the IP address that you want your PI to start

up as or start up with.

So it’s IP equals and then the address.

And then again, like we said before in this video, you need to know what is the subnet

of your existing network and you need to choose an IP address for your PI.

Let’s see if I actually matched what I was supposed to do.

to do oh gosh for the pie yeah 5.1 okay so I’ll move that over to the first thing there yeah so

just 123 is what we wanted so that’s why that is there so I didn’t actually modify this but you’ll

have to modify yours I didn’t because I have to because I already did it and then we’ll go into

the into the root partition so we’ll go into the root partition and notice how it’s got like all

And notice how it’s got like all the files and folders that you’re used to seeing with Linux.

So that means, you know, this is the temporary amount slash pi slash sorry, slash temp slash pi slash root.

Inside of it, there’s a subfolder called home.

And then there’s the home directory for the root account under the root folder.

You could modify that instead if you want to.

I’m just going to go into the home account.

Sorry, the home folder.

And then go into the pi accounts home folder.

because that’s what your PI account is going to start off with.

Again, notice how we’re in like a deeper subdirectory.

So from the PI’s perspective, we’re really only in slash home slash PI.

I already actually did this.

When I jumped away, I wanted to make an extra video for SSH or sorry, for first boot stuff.

So I made the SSH folder.

What you need to do is make directory dot SSH so that you have a SSH folder in this PI folder.

in this pi folder then once you have that go inside of it and you want to make a file called

authorized keys so i did nano authorized keys like that and then i edited it and i just put the public

key of of the machine that i’m currently on right now this is just a virtual machine so i guess it’s

fine if i share but um what you want to do is generate your own ssh key if you don’t know how

but uh you can print out your ssh key with pretty much cat squiggly line or tilde swinton and then

like a slash and then dot ssh and then id and then dot pub so that was my public key that’s how i

found it and then um you know if you don’t have a key you can go ahead and do this on your host

ssh keygen forgot if i put this into the last segment but you type that and hit enter a bunch

of times and when you’re done hitting enter enough you’ll have your public key there somewhere

your public key there somewhere. You probably want to eventually learn how to put a password on your

key but it’s fine for now. So we created the authorized keys file that basically tells

the operating system that I would like that particular key to be able to authenticate as

that user and since the pi is a god user or like a root user it’s pretty nice. The other thing we

have to do is make sure that we set permissions correctly. If the permissions aren’t correct on

your SSH will not authenticate so so I’m gonna make sure that this is set to

the right permissions for me I usually do 7 0 0 on the authorized keys file I

can’t remember if 6 0 is fine so I just put 7 that basically means that your

current user which will eventually be the PI user has full permission to look

at that file but nobody else does so you can tell by the way because on the left

execute and then a bunch of empty dashes meaning nobody else has permissions so we got to do the

same thing for the ssh folder um so i’m going to go uh you know chamad if this doesn’t work by

itself you might want to say pseudo chamad but i think it’ll work because the username that it

thinks is on that folder is actually the same as my current user which is great so i’m going to go

and not the six on there, meaning the current user should be able to actually like read

that directory.

If it’s six, they won’t even be able to read the directory.

So we do that just to make sure that the dot SSH file and the authorized keys file have

correct permissions.

And then I think we’re ready to log into the pie for the first time.

So I’m going to go up.

By the way, if you were inside of root for some reason, I do this sometimes, sudo su

and let’s, oops, let’s go up and then let’s unmount,

whoops, let’s unmount this boot partition

or the root partition.

You may get an error message saying

that the partition is busy

because what you didn’t realize was the account

that you just came from is still considered

in that directory.

So you gotta make sure that there are no terminals

or accounts or anything actually using that directory

before you try to unmount it.

So I’m gonna go sudo, oh, I gotta go up one level.

sudo unmount boot umount and then umount root uh if there are no error messages then that means

the sd card is ready to be put into the actual pi before i do that though i’m going to start

pinging the pi because it’s fun to see the pings come online i’m going to go 192.168.123

because that’s what we chose for the pi already in my other video that i just made i typed like a

here forever on camera. I’m not going to edit it out. So I’m going to take the SD card out

and you can’t really see my Pi because it’s plugged into an ethernet cable, but I’m plugging

an ethernet cable into the Pi. I’m putting the SD card into the Pi and then I’m going to plug power

into the Pi. Totally headless. Don’t have to worry about very much at all. So it’s got power now.

and pretty soon now it should start responding to pings.

Soon as it comes up,

I’m gonna log in and start finalizing the ethernet setup.

There it goes.

Might take like a few more seconds after this

before the SSH server actually comes up,

but I’m gonna give it a try right now and see what happens.

And remember to do PI at,

because we did not make a different user.

When you see this message right here,

that the remote is not recognized that’s a security feature so I’m gonna put yes

and now we’re in the Pi so what I was supposed to do is a network manager connection show at least

this version of the Pi the latest version uses network manager if you’re watching this video

from the distant future you probably just need to you know use whatever tool they have instead of

network manager so I’m gonna edit the ethernet connection and I’m gonna print the connection

the connection details just to double check here.

It’s…

I guess it’s fine.

So now I’m going to set up the IPv4 settings.

So I’m going to go set ipv4.method to manual

because I want a static IP.

Getting dynamic IPs that are also fixed is kind of like another video.

I want to set the address to the one that we just put into the command line.

So 1.123 and give it a 24 block,

meaning it’ll be considered in the same subnet

with other addresses that only have the last number changed.

Then we’ll set the gateway to 1.1,

which is the router address.

Okay.

I’m looking at notes right now, 1.1.

And then we’ll set the DNS.

You don’t actually necessarily need to set the DNS

if you’re, well, I don’t know,

maybe you probably should if we’re doing static right now.

Yeah, you should probably maybe try setting the DNS

as your router, because usually your router

is also your DNS server at home.

If that doesn’t work, maybe try a different number

that you can find online.

This one is, I think, Google DNS.

You just need at least one DNS server,

preferably two or more that works

so you can resolve numbers to names

and your computer can go online by typing names.

So for me, these are my DNS servers.

So I’m just gonna type them in real fast.

Whoops.

And then you don’t need to do this next setting,

You don’t need to do this next setting, but I like to be able to use shorter server names.

So for me, instead of typing… Let me show you what this means in a second. So I’m going to say

my search domain is home because I have a fake domain at home called home. Most people do LAN.

You should probably double check this by saying print ipv4, like print ipv4. And then after we’re

reason I do this is if I ping a server, like let’s say I do router.home, for me that’s too much

typing every single time. If I added that.home search domain, then I could just ping router.

So that’s the only reason that I do that. It’s just a little bit more convenient.

So now let’s remove the setting that we put into the command line so that we have more freedom to

modify the network in the future if we want to. So let’s go to the boot partition.

We’re in the PI right now, so it’s a little bit different.

We’ll go into the firmware subfolder and then we’ll modify that command line file that we

had in before where we were forcing that IP.

We’ll just erase this so that it’s no longer forced because the network manager configuration

we just did should be okay.

And then let’s reboot, reboot the machine.

Do another ping so that I can get online as soon as it comes back up.

Should just take a couple seconds here.

seconds here. So how was your day? How are you? I think somebody let me know if I look weird in

this camera because I have like a new camera with like a viewfinder or not a viewfinder,

like an LCD display. I didn’t used to have that before. I had the oldest, cheapest,

crappiest camera you could possibly imagine. Now it’s just kind of cheap.

lcd you know screen so i’m looking at my own face right now instead of the camera

so tell me if this seems strange or weird to you

but

Okay, so I’m back.

I don’t know where I cut the last video, but basically we had just set a static IP address

on the Pi and then rebooted it and it didn’t come back online.

So I had to stop the video and just try to figure out what I did wrong.

And basically I forgot to tell the connection to start on boot.

So what I did to fix it is I went into the SD card again.

So I did another mount.

I didn’t mount the boot partition.

I only needed to mount the root partition.

and the path that you go into is pretty much this if you’re using network manager

you go into your temporary amount so that’s this first part right here temp pi root and then the

file system from the pi’s perspective this is the path where you can find your system connections so

etc network manager system connections inside of it you’ll see a file for every connection that you

set up on the fail that you just did or that i just did maybe this will prevent you from

failing. Maybe I’ll show you how to set that inside of the Pi too, just to be sure.

So basically we’re just going to edit that connection file. There’s a bunch more stuff

down below, but I just kind of spaced that down so you won’t see it. What you’re really interested

here in this connection file is auto connect. It should have been set to true. And now if we do that,

we should be able to unmount the card and boot the Pi back up and then it should go online.

It’s actually kind of like maybe a good reminder to always include redundancies as a good computer

nerd, right?

Computer scientists, computer nerds, we always like have redundancies in everything.

What I should have done is chose a different IP address for the network manager connection.

That way if I screwed it up, the Pi would still boot under the first address and only

after seeing that it booted with the new address, I could have removed the first address.

But you know, I’m a little impatient and careless sometimes.

I’m going to unmount this root partition and we’ll go back to looking at the

pings, right? That’s the correct ping.

I’m going to remove the SD card from the reader.

I’m going to put it back into the pie and then I’m going to plug in the power.

Okay. Now, hopefully it won’t take long before the pie comes back online.

If it never does, you and me are going to be sitting here.

You and me are going to be sitting here.

Oh, please, come on, what have I done wrong?

Okay, it works this time.

So it was definitely the auto connect.

So now I’m going to go SSH into the Pi.

We already saw that security warning, I think, either in this video or the other video, but

what have I done?

I forgot to put the one there again.

Dumb.

Dumb. Okay, so we’re in the pie. First boot, first connection without even using a computer monitor. Pretty sweet.

So now I’m going to go sudo network manager command line show and then I’m going to edit the ethernet connection

just to show you what we should have set before we saved. It would have been connection.autoconnect.

Connect to yes.

That didn’t change anything, but that’s what I should have done.

I mean, it would have changed something before.

So now we’re inside the Pi, and we’re ready to start setting up more stuff.

So the first thing I’m going to do is, well, I’d like to change the hostname on this Pi.

So I’m going to do sudo nano etc hostname.

There’s a command called hostname I think you can use, but I just like to set it in the file.

So basically, we want to set the hostname of the Pi.

pi that’s not terribly useful for now but I just like it because it shows up on the command line

so I’m going to go pi repeater dot living room dot home don’t judge me for my silly domain names

so now the next time we reboot the pi we’ll have a good domain name then I’m going to do an update

so I’m going to do actually you know what what you should do at home I’m going to omit this just to

sure everybody should do that because the local list of packages that are available needs to be

updated otherwise you might have a hard time installing later it sometimes gets out of sync

and it doesn’t work so we’ll all do update at home you should do upgrade right away i’m not

going to do upgrade right now because it’ll take a long time and then after you do upgrade you

should do auto remove with a dash yes there or just type yes manually again i’m not going to do

And then you should reboot the computer or reboot the PI

then let’s

Install a program called screen which gives us a virtual screen. Let me show you just real fast

What this is for so sudo apt install screen

It’s just basically a virtual screen that you can work on

So if you accidentally lose your connection or something goes wrong, you can log back in and get right back to your work

so I type screen here and I’ll just type like a bunch of random characters and

type like a bunch of random characters and then I will detach from the screen and exit the Pi. So

imagine you lost your internet connection or your network connection. I can go back into the Pi now

and I can list screens with screen-list and then I can reattach to it with a dash R.

Notice how my work is still there. This doesn’t survive if the whole machine reboots but this has

saved me a few times from losing work when I was connected to a remote terminal. Okay so now what

Okay, so now what do we have to do?

The next most important thing that we have to do is install our WiFi dongle.

We have to actually install drivers.

If you’re looking at this video way in the future, I don’t know, maybe the Pi will handle

this.

But right now, as of the making of this video, this dongle doesn’t work unless you install

the drivers from source.

So let me just prove to you real fast.

out. Well, maybe you’ll just have to trust me. At home, do this command IP, whoops, do this command

IP ADDR and hit enter. And you should see two network adapters, you should see Ethernet zero

and also wireless LAN zero. Wireless LAN zero should be already working. It’s not connected

yet, but it’s working. Because well, that’s the one that’s built into the pie. You want also

another one you want wireless LAN 1 like we talked about before for that we have to plug

in the dongle and install the the firmware so I think what I’m going to do now is stop

this video and jump into another one where I just kind of talk about how to install this

dongle so by the time you watch this video that other video should be posted I’m basically

just going to expect that you pause this video and you go over there and you watch the video

If you don’t have the same dongle as me, that’s okay.

The instructions will probably help you get a pretty good idea for how to do it yourself.

And then again, if enough people comment about the same…

I don’t know if I said this before.

If enough people comment asking me to make a video for the same dongle,

I might buy the dongle and then just try to install it for everybody.

We’ll see what happens.

So I’m going to cut the video now.

Go to the other video that shows you how to install the dongle, and then we’ll continue.

Hey everybody!

Thanks for watching this video again from the bottom of my heart.

I really appreciate it.

I do hope you did learn something and have some fun.

If you could do me a please, a small little favor,

could you please subscribe and follow this channel or these videos

or whatever it is you do on the current social media website

that you’re looking at right now.

It would really mean the world to me and it’ll help make more videos

and grow this community.

So we’ll be able to do more videos, longer videos, better videos,

or just I’ll be able to keep making videos in general so please do do me a

kindness and and subscribe you know sometimes I’m sleeping in the middle of

the night and I just wake up because I know somebody subscribed or followed it

just wakes me up and I get filled with joy that’s exactly what happens every

single time so you could do it as a nice favor to me or you could you control me

if you want to just wake me up in the middle of the night just subscribe and

then I’ll just wake up I promise that’s what will happen also if you look at the

look at the middle of the screen right now you should see a qr code which you can scan in order

to go to the website which i think is also named somewhere at the bottom of this video and it’ll

take you to my main website where you can just kind of like see all the videos i published and

the services and tutorials and things that i offer and all that good stuff and uh

if you have a suggestion for uh clarifications or errata or just future videos that you want to see

want to say hey what’s up what’s going on you know just send me a comment whatever i also wake up for

those in the middle of the night i get i wake up in a cold sweat and i’m like it would really it

really mean the world to me i would really appreciate it so again thank you so much for

watching this video and um enjoy the cool music as as i fade into the darkness which is coming for us

Thank you.

Hey there, let’s talk about using your Raspberry Pi as a Wi-Fi repeater, Wi-Fi extender, just

to help make the Wi-Fi signals a lot better in your home.

So for starters, I just want to make a disclaimer. It’s actually a lot cheaper and easier to just go

to the store and buy a Wi-Fi repeater. But if you’re like me, and you like to do everything

and fun why bother driving down to the store when you can stay inside all day long and do it yourself

so uh uh i’m using an old raspberry pi that i found in a drawer this is like a raspberry pi

4 it’s not really that old um after i do this video i’m going to do the same thing with the

raspberry pi 3 which i think should probably also work um and i was about to throw this pi 4 away

and then i realized i could turn it into a repeater so it actually did save me money in the

let me just talk about your your prerequisites real fast what you

actually need you obviously need a Pi you know in like the power and all that

stuff you need an SD card so that you can write an operating system to the Pi

hopefully if you’re watching this video you already know that but the the major

thing that you actually need that you probably don’t have yet is you need an

extra radio you need an extra Wi-Fi adapter for your Pi because the Pi by

radio antenna, you know, Wi-Fi adapter, Wi-Fi card. But you need two because one is going to

connect to your existing router, your existing Wi-Fi access point. And then the second one is

going to become its own access point so other clients can connect to it. Let me kind of show

you a plan of what I’m talking about here. I made a crappy diagram. I hope you like it. I’m not very

good at these things. But if you kind of look on the screen right now, you can see that this is

This is the situation before you add some sort of a Wi-Fi repeater or the Pi repeater.

So this was what was happening to me.

Spoiler, I already did this.

So I kind of remember how to get this working pretty quick.

So I have like a wireless router here and it’s also the regular router

and it’s connected to the modem and stuff.

And the devices that are close to the router get lots of fast, good connection.

But the devices that are kind of far away, like way over here in the back,

here in the back maybe like a server a printer another laptop a phone whatever they lose

connection they they have slow speeds they’re spotty they’re frustrating right i think probably

most of you deal with this um so the the wireless repeater or the pi that we’re going to do right

now is going to solve the problem at least hopefully or mostly i don’t know so i’m going

to show you a diagram of what it’ll be like when we’re finished we’re actually going to create a

a second network. Notice how on the first slide, oh, I already lost it. Let me do it.

Notice how on the first slide, we just had one network here. For my personal network,

this is just 192.168.1.something. And then that slash 24 means the last number is able to change.

We usually call this a subnet. Honestly, this is not smart to have a standard subnet in your

home network, but I’m kind of lazy. Maybe I should change that soon. You should know in advance,

in advance this is part of your preparation and research you should know what is the ip address

of your router your existing router you should know the existing subnet that you’re running on

if you don’t this is going to be extremely hard for you to do most people though if you just get

a router and install it it’s either going to be a one right here or a zero right here very rarely

will i see people with like a 10 0.0 dot something and if they do somebody else in their family or

or business set it up for them already so we start off with only one subnet one network all

only one subnet one network all the devices can talk to each other without

all the LAN devices can talk to each other without routing when we’re done

we’ll end up having two networks so just notice real fast again this is the

initial network you know this is the thing that we had before 192.168.1.

something and then these close devices they’re still going to connect to the

router notice how you know this green line right here it’s not or sorry this

well no it doesn’t I’m totally lying oh no no I am not lying I lied about lying

basically the router is connected still to the original devices that were fast

on the router so there’s no reason to move devices that didn’t have a problem

but notice here instead of having one long blue line going all the way to the

devices in the back this this this blue like connection squiggly you know image

the internal radio of the Raspberry Pi.

And then the Raspberry Pi will have a second antenna

that’s going to be, you know, one of these things.

I’ll show you how to install this and all that stuff in another video.

I’ll talk about it.

That second radio is going to connect and be an access point

to all the other devices that are far away.

And if we’re lucky, what will happen is the signal won’t get too bad

by the time it hits the Pi.

It’ll probably be like, you know, hopefully okay.

okay, kind of fast, not too spotty, at least, you know, not as spotty and bad as it was going all

the way to the devices in the back. And then because this is digital, the Pi is going to

actually repeat the signal out on the second antenna from, from scratch. Like it’s going to

give a fresh signal. It’s going to be the same data, but it’ll be, you know, renewed, repowered.

So if you think about it, that’s kind of like having the wireless router a lot closer to the

lucky then the devices in the back will have a much easier time connecting so and and getting

speed and being reliable and all that stuff the only thing that we really need to deal with though

is in order to do this we have to create a second subnet so at the very end of this video we’ll

talk about routing and we’ll just we’ll just do a couple of commands to make sure that um

the devices in the regular part of your lan network can actually reach and connect to and

end. We’ll add a static route to make sure that these two subnets can talk because by default,

they wouldn’t be able to talk to each other. If you don’t really need them to talk, like let’s say,

I don’t know, maybe these devices in the back, maybe they’re just like your phone or

a computer that you only surf on or something like that. Then you don’t really need a route

if you’re not going to connect to one of those devices in the back as a server or something.

So, but you know, that’s what I like to do. So we’re going to do that also.

the first step, let’s see. I think the first step, oh, before we get the pie started,

we need to talk about your plan. So what is your plan? We’re going to, what happened there?

I lost, there we go. Okay. We’re going to plan what IP addresses the pie will have when we’re

totally done. You have to do this in advance, right? So we already talked about, you have to

might not be the same as mine and then we have to identify or not identify we have to choose what

the repeater subnet is going to be you don’t have more than one subnet if you don’t even know what

I’m talking about you could probably just choose any number you want for me I chose 192.168.5.0

keep in mind you probably want to have the first two numbers the same unless you’re in some sort

of a special setup you know there are numbers that you can use that are not that but this is

change that third number from a one to a five indicating there’s like a now now a dot five

something subnet uh remember that this slash 24 means that only the last number can change

for communication to work without routing so that means i don’t really want to interfere with my

existing subnet if i did you would probably mysteriously continually lose connection

while you’re trying to set this up and then later when it’s working so just

take it from me it’s more trouble than it’s worth so just come up with a new subnet

just come up with a new subnet if you’re thinking about doing bridge networking you can’t really do

that with a wireless radio that is connected in client mode I already tried that it didn’t work

so I mean for me I just had to make another subnet so write down whatever you decide as your

as your other subnet walk around and make sure that it doesn’t exist look in your router this

is the IP for my router at least right now and you should determine what your router IP is and then

And then you have to come up with three IP addresses for the new Raspberry Pi setup.

So the first IP address is going to be, what are we going to assign to the Ethernet port?

I said originally, this is just going to be, you know, a Wi-Fi repeater.

So we’re not really going to use Ethernet, except at the beginning, when we’re setting everything up,

it’s going to be much more convenient to be able to connect to the Pi.

Me, when I was practicing this yesterday, I kept screwing up the wireless settings.

And if I had not set up the Ethernet port in advance, I would have been locked out of the Pi.

I would have been locked out of the Pi. I would have had to like restart it and then hope for the best or maybe rewrite the whole card.

So, you know, once you get the Ethernet port working and you know, you can connect to it,

it makes things a little bit easier if you should screw up the wireless.

So then come up with an IP address for the built-in radio, the one that’s going to connect as a client to your existing network.

For me, I chose 147 and then obviously for the Ethernet 123.

Then you have to come up with an IP address for the second radio on your Pi.

you know, the antenna that’s going to become an access point, it should be on the new subnet.

So whatever you choose up here, you know, 5.0 slash 24, that means 5.something is valid.

I just chose 5.1 because it’s kind of a common thing that the gateway that is sort of like

handling traffic for other machines, which is what the antenna is going to do, is it ends in a 1.

So I’m just going to choose, you know, 5.1 because that’s kind of a standard gateway thing.

address is ready, I’m going to start installing the Pi. So the first thing that you want to do

to get ready to install the Pi, 12 minutes, that’s not too bad. I tend to talk a lot.

I got to chill, you know, I got to chill.

Is you probably want to go to the Raspberry Pi website. So I’m going to go raspberrypi.com.

What is this new stuff? I got to set up Firefox. Raspberry Pi, the foundation has got like an

and a com I think org is like more for community stuff so go to raspberrypi.com

click on software and let’s see so you could use the imager if you want to I’m

not going to show you how in this video I like to do everything manually what

we’re gonna do is download an image of the Raspberry Pi operating system and

then burn that to the SD card for the Raspberry Pi so again you know if you

if you don’t want to do it this way you can do it whatever way you know how you

the OS basically. If you’re interested leave a comment I am thinking about

making future videos where I explain how to do this from Windows but I’m in

Linux right now so I’m just gonna use Linux to do it. I’m on the Raspberry Pi

4 which supports the 64-bit operating system you should use that if your Pi

supports it. On my Pi 3 I’m only 70% sure that it supports the 64-bit

operating system I haven’t like fully explored it yet although it did run I

run. I don’t know if anything was broken, but I’m just going to click on the 64-bit operating

system. So you click that. Then you have, you know, choices like not flavors, but like levels

of stuff that comes pre-installed. So the 64-bit, double check that. Raspberry Pi OS, double check

that. Yeah. With a desktop, we don’t need a desktop for our repeater. Desktop with recommended

software, we don’t need that. We need the light version. That’s the leanest, meanest version.

that is the easiest and fastest to download install so click that download

button and what will happen is you’ll end up with an XZ let me copy that link

real fast you’ll end up with an XZ extension when you download it notice

how it says you know arm 64 light image XZ that just means the image is zipped

up so that’s that it’s faster to download if you had something that was

had something that was like that ended in a gzip extension then on the command line you would say

g unzip and then you would do you know the file name dot gzip or whatever it was since we’re using

uh xz i think it’s uh un xz as far as i recall let me open up a terminal real fast and i’m going to

go into my downloads and then another disclaimer i’m not really going to show you the basics of

about that in other videos um definitely uh command line basics i think maybe soon i’m going

to post um an ssh tutorial so if you’re like on windows and you want to be able to connect or do

command line stuff just basically see my other videos by the time you find this one uh you’ll

probably there’ll probably be a lot others that are up so i’m going to go into downloads here

and go into my iso folder i just like to keep things organized so

Yeah, that’s what I originally did.

So that’s the command to unzip an XZ zipped image file.

So now I just have regular dot image.

I don’t need to unzip it is what I’m saying.

So I would have done, if you don’t have XZ,

you can do apt search XZ on your computer.

It’s in here somewhere.

Yeah, I think it’s a XZ utils that’ll allow you to unzip.

So anyway, the next thing that I really need to do now

that I have the image is I need to burn it to an SD card.

it to an SD card and then I need to modify it for first boot which I think I will do in in another

video that I’ll link here or or mention here so again what am I doing I have like an SD card

it’s like a really you know small micro SD card for the Raspberry Pi and then I have a little

SD card reader and writer so I’m just gonna this is the first time I’ve used this one I have a

really cheap one behind me that sucks and I’m hoping this will be faster so I’m just gonna

stick it in and then so now the card is on USB so then I’m just gonna go plug

this in and oh hang on before you plug it in I almost forgot you don’t have to

do this but it’s kind of a good idea it makes it more convenient I’m gonna use a

program called parted to see what like disks and partitions and drives and

things I have available in the system so sudo parted if you don’t have that

it’s sudo apt install parted. I’m gonna say print devices and notice how it just

shows only one disk. This is a virtual disk because I’m actually in a VM right

now. So now that I know what disks are currently in the machine it’ll be easier

to see what disk just got added. So I’m gonna like push this in here. I saw a

spark! No that was a light. I’m gonna wait a second and then I’m just gonna very

machine to give that usb device to the machine that you’re looking at right now so you don’t

have to worry about doing this um genesis logic reader and writer the cheapest thing i could

possibly find i don’t know it seems okay though it was a it was a choice on the shopping website

that i went to okay so i mean this this proves that it worked i get annoying pop-ups uh because

basically i have like another operating system already on that card so if you get these pop-ups

you had something on the card before you probably want to unmount the card before you continue so

we know now that the card is uh showing up as dev sdb got to remember that and uh before i continue

i’m gonna unmount so you want to go mount this is linux again by the way and i’m gonna oops well

mount and pattern match it by sdb and those are the two mounts that i have so i’m gonna just

rid of that because if you try to modify a card that is currently mounted or a

partition or a drive or something that’s currently mounted you’ll probably end up

corrupting a bunch of data so you don’t want to do that mount pattern matching

against SDV so now it’s unmounted I don’t know if this is 100% safe at this

point but this is what I do so hopefully it’s okay just print the devices again

to make sure it didn’t disappear if it did disappear you probably have to like

unplug it and replug it or maybe reboot the computer because you use the wrong

because you use the wrong command or you click the eject button or something.

So now I’m going to write that image directly to the cart.

So I’m going to say sudo dd.

So this is the program that I use for writing images to disks and cards

and copying files and stuff like that.

It’s really cool and fast and versatile,

but be very careful because you could actually destroy your entire computer with this command.

So what am I talking about?

talking about so you have to specify the in file and that’s pretty easy uh if you get it wrong it

doesn’t really matter so i’m specifying the in file as that image that i just downloaded

then i’m going to specify the out file and this is where it gets super dangerous

you have to double and triple check that you’re typing the correct device and you’re typing the

device correctly so i’m literally going to look at it like five times i go out file dev sdb

devsdb has the right size that’s a 64 gigabyte sd card there’s nothing else except for my okay

you got to be paranoid because i i’ve done this one time in my life i used the wrong out file

and i basically watched my computer destroy itself in front of my face

and a little tear went down my cheek slowly anyway so then the other thing that i usually

like to put on here is conv fsync i don’t know if this is required for sd cards but it’s usually a

It’ll basically force syncing of the file.

Because like, for example, if you have a USB thumb drive

and you use DD to write data to the file,

the thumb drive sometimes lies to you

and tells you that data is written

even though it hasn’t been written

because the thumb drive is trying to appear

faster than it really is.

So if you just kind of notice that the command is finished

and you pull out the thumb drive,

you might have corrupted data

because it didn’t actually finish writing.

So I use conv fsync to try to avoid that.

And then I’m going to do status equals progress.

progress. So I can just kind of see what’s going on. Okay, so let’s see, double check FSDB and then

it’s all plugged in. Everything’s good. Okay, wish me luck. Then again, this is why I’m in a virtual

machine. If this gets destroyed, I don’t really care as much. Okay, it’s going incredibly slowly.

Just as slow as my old slow card reader. That sucks. Maybe the problem is my hypervisor then,

from this host machine to my virtual machine.

Okay, anyway, so I’m going to cut the video for a second here.

And hopefully you’ve gotten this far with me

and you’re ready to go to the next step.

Just maybe pause the video while yours is riding to the Pi.

And I’ll turn off my video now.

I’ll come back as soon as it’s finished.

And then we’ll continue.

We’ll do first boot on the Raspberry Pi.

Be right back.

Hey, everybody.

Hey everybody! Thanks for watching this video again from the bottom of my heart. I really

appreciate it. I do hope you did learn something and have some fun. If you could do me a please,

a small little favor, could you please subscribe and follow this channel or these videos

or whatever it is you do on the current social media website that you’re looking at right now.

It would really mean the world to me and it’ll help make more videos and grow this community.

So we’ll be able to do more videos, longer videos, better videos, or just I’ll be able to keep making

keep making videos in general so please do do me a kindness and uh and subscribe you know sometimes

i’m sleeping in the middle of the night and i just wake up because i know somebody subscribed or

followed it just wakes me up and i get filled with joy that’s exactly what happens every single time

so you could do it as a nice favor to me or you could you control me if you want to just wake me

up in the middle of the night just subscribe and then i’ll i’ll just wake up i promise that’s what

will happen also uh if you look at the middle of the screen right now you should see a qr code which

you should see a QR code, which you can scan in order to go to the website,

which I think is also named somewhere at the bottom of this video.

And it’ll take you to my main website where you can just kind of like see

all the videos I published and the services and tutorials and things that I offer

and all that good stuff.

And if you have a suggestion for clarifications or errata or just future videos that you want to see,

please leave a comment.

Or if you just want to say, hey, what’s up?

What’s going on?

You know, just send me a comment.

going on you know just send me a comment whatever i also wake up for those in the middle of the

night i get i wake up in a cold sweat and i’m like it would really it really mean the world to me i

would really appreciate it so again thank you so much for watching this video and um enjoy the cool
