So have this issue where nixos sometimes cannot connect to the internet. usually happens after i use windows for uni work. then when i go back to nix my network device wont show up. i tried a few fixes like adding these settings to my config
boot.kernelModules = [ “i8042” “iwlwifi”];
and
hardware.enableAllFirmware = true;
networking.networkmanager.wifi.backend = “wpa_supplicant”;
→ ip link show
