Ubuntu 22.04 is not seeing WIFI on an AX1675 card, but bluetooth is working.

Some folks have suggested adding the AX210 firmware for iwlwifi, but Ubuntu 22.04 has this firmware already installed in /lib/firmware.

sudo dmesg | fgrep -i iwl

reveals:

[   16.024768] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)
[   16.026718] iwlwifi: No config found for PCI dev 51f0/1671, rev=0x370, rfid=0x2010d000
[   16.026727] iwlwifi: probe of 0000:00:14.3 failed with error -22

Any assistance would be greatly appreciated - thank you.

Fixed by installing backport-iwlwifi-dkms per chili555's suggestion.

After installing and rebooting, the:

sudo dmesg | fgrep -i iwl

yields:

With an internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install backport-iwlwifi-dkms

Reboot and show us:

sudo dmesg | grep iwl

    chili555 - installing the backport-iwlwifi-dkms package followed by a reboot did the trick (thank you!). For posterity, I included the results of dmesg | grep iwl in the original post. – Fuzing Jul 18 '22 at 20:46
  • Awesome! Glad it's working. – chili555 Jul 18 '22 at 21:23

    I am also running Ubuntu 22.04 on Alienware x17 r2. My AX1675 WiFi driver was not detected either. Running the first two commands worked for me too.

    Thank you so much!

  • Is anyone else encountering stability issues with this fix? when wifi is enabled getting hard crash with everything becoming unresponsive, disable wifi and everything works fine – Simon Nov 29 '22 at 18:54
