Wifi not working Ubuntu impish 21.10 Kernel 5.13.0 Samsung Galaxy Book Flex2

community,

i get a Galaxy Book Flex2 (NP930QCA-KA3DE) from work. Windows goes completely to trash :), formated the whole disk and installed Ubuntu imprish.

Wifi don't work as you see in the logs and i can't find any other solution in the internet and posts here. Tried some thinks like install kernel 5.14 from kernel.ubuntu or installing the "hwe-edge kernel" but it doesnt help. Im again on 5.13.0 imprish standard. So i wanted to ask your for help step by step so that we can help other too to bring the machine like this working.

Should i have to install the 5.15 kernel?

Here are my logs and harware posts:

Update #1:

Note: Excerpt/edited from Intel AX201 Wi-Fi 6 is not working on Ubuntu 21.04

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.

• (re)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-9340

• Edit the dkms.conf file in the source code directory /usr/src/backport-iwlwifi-9340

  • sudo -H gedit /usr/src/backport-iwlwifi-9340/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-9340/drivers/net/wireless/intel/iwlwifi/pcie

  • sudo -H gedit /usr/src/backport-iwlwifi-9340/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/9340

  • sudo dkms add backport-iwlwifi/9340

  • sudo dkms build backport-iwlwifi/9340

  • sudo dkms install backport-iwlwifi/9340

• reboot normally

Retest networking.
