rtl8812au Wifi driver not working under linux 5.3.0-26

[Vibhav Bharti]

rtl8812au Wifi driver does not seem to work under linux kernel '5.3.0-26-generic' with my Xubuntu 18.04. I have used 'rtl8812au-dkms' driver from the repo and that has failed. I also compiled with dkms and directly with make and they also fail to work.

I reverted back to '5.0.0-37-generic' and it works okay.

Status changed to 'Confirmed' because the bug affects multiple users.

This work for me: https://askubuntu.com/questions/1149117/tp-link-ac600-archer-t2u-nano-driver-for-ubuntu-18-04/1191835#1191835

I think I did try that before. That is where I found aircrack-ng one as well. It didn't work on that kernel for me. So I just reverted to my older one, which was plug 'n' play with my NETGEAR A6100.

I have the same problem.

Still not working under 5.4.0-31 (groovy gorilla alpha) either.

If I remove the rtl8812au-dkms package and build the driver from /usr/src/8812au-4.2.3, that older version works fine. The problem is, that older version needs to be rmmod/modprobed every day or two or certain apps start hanging at specific network operations (logging into EVE Online, for one).

I tested with the 5.6.4.2 driver from the aircrack repo (https://github.com/aircrack-ng/rtl8812au), and that one works with my USB dongle. [yay!]

I did have to re-enter the WPA2 key in network manager in order to reconnect to my wireless, which was odd - but this is the first version newer than 4.2.3 that actually activated the dongle and enabled the USB light on my particular device.
