Iwlwifi: Your Wifi Is Working
Sometimes, specially when you are using Arch, after using pacman -Syu
, and updating linux-firmware
, you will find that there is no wifi present after rebooting. Donot panic, there is a bug in firmware for iwlwifi which block your system to load latest firmware for iwlwifi. Just issue command journalctl -p 3 -xb
, this will let you know that firmware file is not loading (I dont recall the exact error message).
sudo mv /usr/lib/firmware/faulty.ucode.xz /usr/lib/firmware/faulty.ucode.xz.back
Thats is all. your wifi will be up in no time!
