I haven't seen a posted workaround for this anywhere so here is what I
found to work on both v20.04 and v22.04:
For those loading iwlwifi-QuZ-a0-jf-b0-XX.ucode, use the 55 version as
shown:
/lib/iwlwifi-QuZ-a0-jf-b0-55.ucode
I just moved all newer firmware that are higher than 55 out of the
/lib/firmware directory.
In v20.04, after removing newer firmware, it just auto loads and starts working.
In v22.04, you must reboot after removing the firmware that is higher than 55.
So something changed after v55 that broke the wireless functionality on
the 440 G8 with AX201.
Here is a before and after hardware snapshot:
