After software update of kernel on ubuntu 22.04 TP-Link ac600 archer wifi adaper stopped working

Question

My kernel version now is 5.19.0-32-generic on Ubuntu 22.04.1 LTS.

Adapter was working in 2g and 5g modes perfectly before software update.

I tried some methods as shown here for 20.04 and earlier versions. But no success. I am stuck up.

Can anyone help with tried method?

Did you install any drivers for it? They probably didn't build for the new kernel. — Pilot6, Feb 17 '23 at 14:56
When the driver for new kernel version 5.19 is released, kindly notify. — RPS, Feb 18 '23 at 16:44

To solve my problem i had this commands:

Remove the old and problematic driver:

sudo apt purge rtl8812au-dkms

Install the new one:

git clone https://github.com/morrownr/8821au-20210708.git

cd 8821au-20210708

sudo ./install-driver.sh

I have used with sucess the proposed solution defined at Unable to install USB WiFi device RTL8812AU

Thank you so much, this enabled me to perfectly access the internet on 22.04. Much easier than on 20.04. – C26 Dec 02 '23 at 17:52

I couldn't get it to work with kernel 5.19.0-32-generic either.

I was able to solve it by changing grub to the previous kernel 5.15.0-60-generic.

Step by step: Install Grub Customizer

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Open Grub Customizer Click the General Settings and select "predefined" button, then the option of 5.15.0-60-generic kernel. It is a temporary solution until someone fixes the driver.

Now you can restart your computer.

Followed this procedure and it started working fine. Thanks for this temporary solution. – RPS Feb 18 '23 at 16:45
It is not a good idea to freeze kernel. It is not hard to fix it with 5.19. – Pilot6 Feb 18 '23 at 16:48
This also worked for me. Downgraded the kernel, wifi working again. Thanks for the tips.

@Pilot6 You are right; it is a temporary solution until someone fixes the driver. I'll edit my answer. – jaguarnet7 Feb 21 '23 at 10:18
