I am new to Linux-Ubuntu and I am currently dual booting with windows. I had no issues with wifi initially but lately my system could not detect the wifi adapter.
I tried a couple of solutions from
Unable to get wifi adapter working - clean 19.04 install - network unclaimed
Intel AX200 wifi card not found on ubuntu 20.04
some suggested following the instructions here
dmesg | grep iwl showed
[ 3.377570] Loading modules backported from iwlwifi
[ 3.377571] iwlwifi-stack-public:master:8613:3ae69204
[ 3.559520] iwlwifi 0000:3f:00.0: enabling device (0000 -> 0002)
[ 3.917475] iwlwifi: probe of 0000:3f:00.0 failed with error -110
I am not sure if there is suppose to be any response when running sudo modprobe iwlwifi but there were none
nothing seems to be working. (disabling fastboot/ secureboot makes no difference)
I would really appreciate it if anyone can help guide me through this.
edit:
couple of days ago I updated my Wifi driver from windows and the wifi adapter was found on linux and it was working again. However, due to the recent update of ubuntu, the wifi adapter is not found again.
lspci -vnn | grep Network
so that a real expert can advise you further.
