Kernel 5.11.0-22 crashed my WiFi dongle

[gittist]

I just installed the above Kernel and no WiFi. I went back to 5.8 and it's working again.

When I first installed this WiFi Dongle I had to do the following to make it work:

sudo apt install git dkms
git clone https://github.com/cilynx/rtl88x2bu.git
sudo dkms add ./rtl88x2bu
sudo dkms install rtl88x2bu/5.6.1


This is the antenna: https://www.newegg.com/p/0XM-01AV-00017 ... N04B7V9793

Maybe I need to change the commands but honestly I have no idea what to do.

Any help would be appreciated.

Usually you need to repeat the build process with each new kernel.

You might have to uninstall that and download the updated version as there are limits as to what even dkms can do.

Luckily I haven't had to do that in the past.. I think what you mean is doing the SUDO commands I listed earlier. Can I do that and then upgrade to the new Kernel? If I update to the new Kernel first I have no internet to then do the build. Is that something I could put on a thumb drive?

Sorry to be so dumb.

P.S. After reading (although I may have misunderstood what I read) that DKMS is supposed to be updated along with a new Kernel, I reinstalled Kernel 5.11.0-22 and got the same results, no WiFi.

I ran "dkms status" in the command box and the latest version of dkms installed is "rtl88x2bu, 5.6.1, 5.8.0-59-generic, x86_64: installed"

Maybe I should just revert back to an earlier Kernel and wait for the systems to catch up?

If you wish, You can install same driver from PPA repository with following commands. The driver in the PPA repository also has kernel 5.12 patch.

Code: Select all

sudo add-apt-repository ppa:kelebek333/kablosuz
sudo apt-get update
sudo apt install rtl8822bu-dkms

This seems to have worked . So far I still have WiFi. Now when I run the dkms status command i get:

rtl8822bu, 5.6.1.6~ppa, 5.11.0-22-generic, x86_64: installed
rtl8822bu, 5.6.1.6~ppa, 5.8.0-59-generic, x86_64: installed (WARNING! Diff between built and installed module!)

How do I take care of the warning?

Its not important. You can try following commands for rebuilding module if You want.

Code: Select all

sudo dkms remove rtl8822bu/5.6.1.6~ppa -k 5.8.0-59-generic

Code: Select all

sudo rm -f /lib/modules/5.8.0-59-generic/updates/88x2bu.ko /lib/modules/5.8.0-59-generic/kernel/drivers/net/88x2bu.ko

Code: Select all

sudo depmod -a 5.8.0-59-generic

Code: Select all

sudo dkms install rtl8822bu/5.6.1.6~ppa -k 5.8.0-59-generic
