i also tried to follow the instructions on this page
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release and also downloaded the firmware file from here https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi and copied it over to /lib/firmware

i also tried to boot in insecure mode but doesnt work either.

FYI, my kernel version is 5.4.0-42-generic and I'm running only ubuntu 20.04 on my PC (not dual-booting)

Does anyone know of a solution to this problem?

AX200 (rev1a) I had the same issue. I have dual-boot (win10, ubuntu) and I turned fast boot and secure boot in BIOS, but wi-fi still didn't work. Now I found that after command:

$ sudo dmesg | grep iwl

I saw an error: failed with error -110

And I found conversation, that I need turn off in Fast Boot in Windows too.


It helped me. It was a lot of time..
