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)

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!
