The wifi settings page complained that no wifi adapter can be found. here's some relevant information

lshw -C network

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?

drivers kernel iwlwifi 20.04
