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? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1902424 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 Description: Ubuntu 20.04.1 LTS Release: 20.04 $ apt-cache policy linux-firmware linux-firmware: Installed: 1.187.3 Candidate: 1.187.3 Version table: *** 1.187.3 500 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main i386 Packages 100 /var/lib/dpkg/status 1.187 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal/main i386 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1902424/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
