Lets se what this shows

dmesg | grep iwl

I think I have to restore my laptop, cuz it is freezing now without any operations.

Try

cd backports-5.14.13-1
sudo make uninstall

Reboot and we will see if the backports caused it

Hi,

I did not uninstall that because I can't boot. However, I tried to restore the system (which is backuped before I installed backports-5.14.13-1)

Anyway, I think it's good news that at least backports-5.14.13-1 will make the system detected the Killer wifi card.

I wonder if we needed to delete the /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm file for it to work

Hi,

Do you mean that I should try to install backports-5.14.13-1 while remove the /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm?

I wonder if it is the driver for the graphics that is causing the issue, what is the result for

dpkg -l | grep -i nvidia

We might need the driver version from a newer Ubuntu version for it to work

Hi, thank for your help.

Probably, I just wait for Ubuntu hwe update to cover this WIFI card. I tried some kernels, they are not compatible.
