My Intel Wifi 6 AX210 card is not detected on my fresh Ubuntu Mate installation.

Here is the dmesg output:

[    3.341328] iwlwifi 0000:92:00.0: enabling device (0000 -> 0002)

[    3.857218] iwlwifi 0000:92:00.0: Failed to run INIT ucode: -110

My kernel version is:

Linux Precision-7560 5.11.0-27-generic #29~20.04.1-Ubuntu SMP Wed Aug 11 15:58:17 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Any idea to correct this? Linux Kernel from 5.10 may support this Wifi card : https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html

Thanks.

For 20.04 (focal fossa)

This is a well-known bug #212371

Let's try the suggested fix:

  1. Open a terminal by pressing Ctrl + Alt + T .

  2. Run the following command:

    sudo mv /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm  /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.bak

  3. Reboot to reload the drivers.

EDIT: It appears that periodic updates to the package linux-firmware will install a new version of the offending file iwlwifi-ty-a0-gf-a0.pnvm and so this process will need to be repeated.

Good Luck!

Alternatively, installing a newer kernel will fix this issue. In the bug report, users have specifically mentioned kernel 5.16 (for 20.04 only). Here are step by step instructions to install it.

  1. Change the working directory to ~/Downloads :

    cd ~/Downloads

  2. Download the kernel's .deb files:

    wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-headers-5.16.0-051600_5.16.0-051600.202201092355_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-headers-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-image-unsigned-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-modules-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb

  3. Install the .deb files:

    sudo dpkg -i *.deb

  4. Satisfy the dependencies.

    sudo apt -f install

That's it!
Good Luck!

  • Thanks for the fix. I have uploaded to 5.13 kernel and it works fine now. – Hexa42 Jan 21 '22 at 08:11
  • Thanks for accepting this answer. – Error404 Jan 21 '22 at 08:14
  • I've tried both solutions, neither work. I'm on Ubuntu 22.04 tried and reversed both the kernel update and the pnvm rename. Oddly if I unplug the USB_INT connection, WiFi works, but no Bluetooth. Plug USB_INT in, Bluetooth works, but not WiFi. – Jim Jan 10 '23 at 07:07
  • @Jim Unfortunately, this answer is specific to Ubuntu 20.04. I wouldn't recommend trying this on newer releases (I'll edit the answer to mention this detail). I'd recommend, you ask a new question Nd add all the necessary details. – Error404 Jan 10 '23 at 07:54
  • @Error404 Yep, I recognize that - however it seemed like this was more of a kernel issue vs distribution version issue; so I thought worth a try. – Jim Jan 10 '23 at 08:19
