yes. With iwlwifi-QuZ-a0-hr-b0-48.ucode firmware version there were
issues with WiFi.

There were errors in dmesg like 'Microcode SW error detected' and the
driver would go in a restart loop repeatedly encountering that error
meaning that wifi wasn't connected/not working.

I also had issues tethering my laptop to my android phone hotspot

I downloaded iwlwifi-QuZ-a0-hr-b0-50.ucode from
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git to see if that would work better with the 5.4 kernel but
the issues persisted.

I then upgraded to the 5.8 kernel and these issues persisted with the
iwlwifi-QuZ-a0-hr-b0-50.ucode firmware

I went looking for the iwlwifi-QuZ-a0-hr-b0-56.ucode firmware in the
linux-firmare git repo but couldn't find it in the downloads so I
upgraded my firmware to iwlwifi-QuZ-a0-hr-b0-55.ucode and that seems to
be a lot more stable.

So in short there were instabilities and errors in the firmware that
seems to be fixed with the newer version

On a more general note should we not be shipping the firmware versions
that the kernel is looking for?

Title:
  iwlwifi missing firware for intel ax201

Status in linux-firmware package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 20.04 does not have the correct firmware for the Intel ax201
  wifi 6 wireless card

  This affects both the 5.4 and 5.8 kernels shipped with Ubuntu 20.04

  currently ubuntu has this version of the firmware
  /lib/firmware/iwlwifi-QuZ-a0-hr-b0-48.ucode

  Kernel 5.4 is looking for iwlwifi-QuZ-a0-hr-b0-50.ucode

  Kernel 5.8 is looking for iwlwifi-QuZ-a0-hr-b0-56.ucode

  both kernels load iwlwifi-QuZ-a0-hr-b0-48.ucode as a fall back but
  having the latest firmware is desirable

  
  $ lsb_release -rd
