At first my USB-WLAN cards based on RTL8812AU used to plug and play under Ubuntu. Later it didn’t until yesterday. I installed Mate on a new computer from the newest LTS-ISO, plugged in the RTL8812AU and it worked. I would be glad but it was not my laptop.

How can I update my own laptop so that it can also work with RTL8812AU without reinstalling the system?
Funny thing is that on a yesterdays laptop in system settings, under extra drivers there is an open sourced driver but it is not selected on a list. Instead the ~~device not in use is selected but the card work.

On my machine it is all the same if I select not in use or that extra driver, card doesn’t work. Is there anything I can reinstall but not the whole OS? I’m sitting on 24.03.3 LTS updated from ISO I installed one year ago.

You should just be able to reinstall or update the driver package (rtl8812au-dkms) from the repositories or GitHub.

Thank You but it doesn’t help. From a freshly installed 24.04.3 it just works, without githubs and any additional action. I can’t force my 24.04 installed as 24.04.01 to use this chip.

Try this.

sudo apt install git
git clone https://github.com/morrownr/8821au-20210708.git
sudo dkms add ./8821au-20210708
sudo dkms install rtl8821au/5.12.5.2
