dmesg | grep wifi

[   34.807020] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)

How to fix this in nixos?

as of late December 2021

https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi

AX211 doesn’t seem to be supported yet, in any linux kernel. :slight_smile: .

while on one device the error is gone and the new/old cart gets recognized (a network wlpxx is shown)

  • there is no wifi connection
    (but wifi works normally on win10)

on the second device the error stats (after a rebuild)

update:
still the same error

  • but kernel (5.15) should now support the card?

Does anyone (nixos-user) successfully uses Wifi via a Wifi 6E standard or more precise an intel card AX211
