I'm trying to learn Linux and having trouble with wifi. I am running Ubuntu 21.04 with 5.11.0-22-generic kernel. I have no options under the network tab in settings for wifi as if my wifi card is not detected. I have searched and tried just about every solution i could find on this forum and nothing seems to work. I have downloaded the appropriate drivers from the Intel website and moved the files into the /lib/firmware directory as it says to do in the README file. Wifi works fine when I boot into Windows. Ubuntu is installed on an external SSD. I'm not quite sure what all information is needed to troubleshoot this issue but I have provided what i have so far. Thanks for the help.

The problem is with the iwlwifi kernel module. It doesn't recognize the latest Intel AX201 modem card. Why? Because iwlwifi isn't coded for the device codes of the Intel AX201!

Let's patch the iwlwifi kernel module so that it works with the Intel AX201.

  • Install Ubuntu 21.04

  • Boot to the 5.11.0-2x kernel from the GRUB "Additional Options" menu

  • Install backport-iwlwifi-dkms

    • sudo apt update

    • sudo apt install backport-iwlwifi-dkms

    • This will fail to fully install on kernels > 5.4.0. This is expected.

    • This software installs source code into /usr/src/backport-iwlwifi-8613

  • Edit the dkms.conf file in the source code directory /usr/src/backport-iwlwifi-8613

    • sudo -H gedit /usr/src/backport-iwlwifi-8613/dkms.conf

    • Edit the file and change OBSOLETE_BY="5.4.0" to #OBSOLETE_BY="5.4.0"

  • Edit the drv.c file in the source code directory /usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pcie

    • sudo -H gedit /usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pcie/drv.c

    • Enable "Display line numbers" in Gedit preferences

    • Add the following line below the other 0xA0F0 ID lines at #447-#448...

      IWL_DEV_INFO(0xA0F0, 0x6074, iwl_ax201_cfg_qu_hr, NULL),

  • rebuild the patched dkms module

    • sudo dkms remove backport-iwlwifi/8613

    • sudo dkms add backport-iwlwifi/8613

    • sudo dkms build backport-iwlwifi/8613

    • sudo dkms install backport-iwlwifi/8613

  • reboot to the 5.11.0-2x kernel via GRUB, and retest the AX201

  • purge the 5.13.4 kernel

    • dpkg -l *5.13.4* # list 4 linux* package names to purge

    • sudo dpkg -P package_name#{1|2|3|4} # do this for each of the four package names

  • sudo update-grub # update GRUB

  • reboot normally

  • file a bug report at https://bugs.launchpad.net/ubuntu against package linux-modules-extra-5.11.0-25-generic running on a Samsung Galaxy Book Flex2 Alpha

Note: Currently installed AX201 firmware can be seen at ls -al /lib/firmware/iwlwifi-Qu-*

Note: If additional newer firmware code is required, see https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-Qu-*

Note: Newer kernels can be found at https://kernel.ubuntu.com/~kernel-ppa/mainline/

  • Thanks !!! @heynnema I'm also samsung galaxy flex2(uses wifi adapter AX-201) user and I got same problem... Your answer saved me When I saw wifi-list I really thrilled and screamed T.T I love you !!!! I would like to comment for the next user. I installed ubuntu 21.04 on 080821, but kernel 5.11.0-16 was built-in. I couldn't find 5.11.0-2x any where, so I used 5.11.1 and it worked.(5.11.16 or 5.13.8 won't work!)

  • @heynnema do you happen to know if this also works for AX-210 or what needs to be changed to get it working? I suspect the addition "IWL_DEV_INFO(0xA0F0, 0x6074, iwl_ax201_cfg_qu_hr, NULL)," might need to be different? Sep 10 at 12:17
