Help for Installing New Intel Wi-Fi 6E AX210

Summary of steps taken as of 11.27.21

Please install a newer and matching WLAN firmare for your Linux Kernel. (e.g. For Kernel 5.4, try newer WLAN firmware: iwlwifi-cc-a0-50.ucode for AX200, it is available from zip file at the Linux firmware git. )

Alternatively, download and install the latest Linux firware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/, which contains the latest WLAN firmware.

2. Then, provide the output of the following commands:

Go to /lib/firmware and remove the iwlwifi-cc-a0-60.ucode:

$ sudo rm -f iwlwifi-cc-a0-60.ucode

$ sudo cp iwlwifi-cc-a0-50.ucode /lib/firmware

$ sudo modprobe iwlwifi

Here shutdown the system, wait for seconds, then reboot.

$ lsmod | grep iwlwifi​

$ lspci

$ modinfo iwlwifi

$ sudo lshw -C network

Note.

While running the 'sudo modprobe iwlwifi', if you receive an error 'modprobe: ERROR: could not insert 'iwlwifi': Operation not permitted ' which may be caused by the UEFI Secure Boot feature; , do the following:

Install mokutil:

$ sudo apt-get install mokutil
Check the status of SecureBoot

$ mokutil --sb-state
In case it is enabled, run the command:

$ sudo mokutil --disable-validation
Reboot, verify things work. And then, enable it again.

$ sudo mokutil --enable-validation
