[SOLVED] Can't get usb WiFi adapter to work. (Pop os)

[masak1]

Hello, I've wasted too many hours on this and decided to make a post. Sorry for the images, I'm writing this on a phone! And I'm using Pop os on the last version that was available in the download page (NVIDIA).

I was able to download the driver however the installation had some errors. I installed it through another computer using Winget (terminal).

My WiFi adapter is the TP-Link Archer T2U PLUS
When I ran `lsusb` it had this: [RTL8821AU] next to the name... I this because I installed the driver? I read that the driver supported this type of chipset

How I installed the driver: (removed first to get the error again)

No matter what I did, it just didn't work.

I need some serious help or I don't think I'll be able to use Linux at all

Welcome to the forums, you will be able to a Linux distribution, whether it is Pop or one of the others,
first let me say POP is NOT a full Ubuntu distribution, it is assembled for System76's own computers, and therefore only carries drivers needed by their kit, If it works out of the box first time , it can be a good [but no better than] other distribution's, if it doesn't work well out of the box, then it can be a right pain in the rear to get it going.

To confirm which chipset you need, please run from the terminal inxi -Nn and paste back the full results, you will need internet access to download and install the drivers correctly, either hard-wired to the router or by using your phone teatherd to the computer
you may need to install inxi from the repository.

Before you buy anything check it out at h-node for compatibility with Linux.

As for graphics drivers just try the standard free neuvaux which I use without issue across three old disparate laptops and one CAD workstation

Good Luck

ps should all fail try installing ZorinOS where everything seems to work straight out of the box on default settings – without touching or tweaking a thing

This might help to identify your problems…?

Hello and thanks!

In the post I explained how I downloaded the drivers with another computer but if that is no good, understood.
I am writing this through my computer, Thanks a lot! The phone trick worked after all!

I installed inxi successfully and this is the result I got:

masak1@pop-os:~$ inxi -Nn
Network:
  Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
    driver: r8169
  IF: enp10s0 state: down mac: 24:4b:fe:cf:46:31
  IF-ID-1: enx3668d8b1bd2d state: unknown speed: -1 duplex: half
    mac: 36:68:d8:b1:bd:2d

@Ziggi thanks for looking that up, I am a bit pushed for time today

@masak1 is not showing device 2 [wi-fi card] so this is the latest driver set for that card https://github.com/morrownr/8812au-20210629

 

[masak1]

this is the latest driver set for that card https://github.com/morrownr/8812au-20210629

Okay, done! I have supposedly, successfully installed the driver
I don't really see many changes thought, I ran inxi -Nn again and same result.

 

[masak1]

By the way I forgot to mention that I Device 1 is the one supposed to work. Not sure if that's relevant or not
Oh and my other message is awaiting moderator approval.. I guess? I just said "done what now"

 

[Brickwizard]

your inxi report has disappeared
device 1 is your PCI ethernet card
If you have a wi-fi card internally or a usb wi-fi dongle, it will show as device 2

to show you what I mean, I have plugged a non-working dongle into my desktop and this is my report

Network:
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
driver: r8169
IF: enp2s0 state: up speed: 1000 Mbps duplex:
Device-2: Realtek RTL8188FTV 802.11b/g/n 1T1R 2.4G WLAN Adapter type: USB
driver: r8188eu
IF: wlx00e04c818802 state: down

Oh yeah that post is still invisible and awaiting moderation... weird.
Anyway I just said that it's the exact same as earlier...
Here:

Network:
  Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
    driver: r8169
  IF: enp10s0 state: down mac: 24:4b:fe:cf:46:31
  IF-ID-1: enxee230545e12f state: unknown speed: -1 duplex: half
    mac: ee:23:05:45:e1:2f

I think it's the same as earlier...
By the way I've seen a few posts that all recommend using the driver from aircrack. But then again... I couldn't get it to work

 

[Brickwizard]

The RTL8169 is the correct driver for your Ethernet, it will show as down unless it is hard-wired to the internet, at the moment you are not showing wi-fi card connected,

Okay! I'll use my phone for the time being... I already downloaded the drive you gave me so IDK haha (I think its conflicting with the one i added before.. who knows..)

Anyway take your time! We can solve this later, thanks.

OK then I'm Back [fed and watered]
Had a thought,, Have you installed your Pop Os direct to the hard drive, or have you installed it in a virtual box/machine

okay so after a bit of tweaking here and there. I found that I actually needed the rtl8812au drivers and that they previously did not work because I didn't have wifi.
I ended up using aircrack-ng's.

I didn't know I had to have wifi start the drivers even after cloning the github! Anyway I actually got it working by using the wifi from my phone with usb tethering.

Thanks for your help, also it's on my hard drive.

 

[Brickwizard]

Well done, I hope you don't have any other problems, If you're now happy, please go back to your first post and add "solved to the title
