After upgrading my kernel from 5.13 the WiFi had stopped connecting and is no longer recognized by iwconfig. Moreover, dmesg contains long error output:

Similar issue is discussed here: Bug #1966793 “Wi-Fi 6 AX201 not working on 5.15.0-23-generic #23...” : Bugs : linux-firmware package : Ubuntu

Temporary workaround is to downgrade the kernel to 5.13.

I had same issue (“Failed to run INIT ucode: -110”) on ubuntu 22.04. Solve by installing backport-iwlwifi-dkms and rebooting. Afterwards it worked again. Maybe give that a try?

My kernel was 5.15

Awesome, thank you so much! Will definitely check it out.

Korvin · September 14, 2022, 10:06am

I can confirm that it works, indeed. Again, thank you very much for the hint! Now writing from 5.15 via WiFi.
