The iwlwifi driver defines a min-max range of supported firmware versions. It tries to load the max version and will go down the list until it finds one it can load. Load failures will show up as -2 errors in dmesg.
The driver also reports the max version via modinfo, the min version is not advertised (needs to be looked up in the kernel source). So for 6.8: $ uname -r 6.8.0-41-generic $ modinfo iwlwifi | grep QuZ-a0-hr-b0 firmware: iwlwifi-QuZ-a0-hr-b0-77.ucode Which is what gets loaded per your dmesg. So to me this is working as expected. You can look at previous kernel logs using 'sudo journalctl -k -b <negative number>' trying to find the dmesg that you think is problematic and post it here. -- 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/2078797 Title: Update to 24.04.01 breaks iwlwifi (Intel AX201) Status in linux-firmware package in Ubuntu: Incomplete Bug description: I updated from 22.04 LTS to 22.04.01 LTS when offered the opportunity. All management options for Wi-Fi and BT disappeared, and I couldn't use wireless access anymore. Checking dmesg quickly shown, that no firmware blog (ucode) can be loaded in the expected version. The files .ucode.zst were there, but for not good use. I had to download the file (iwlwifi- QuZ-a0-hr-b0-59.ucode) manually from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/tree/, reload it (sudo modprobe iwlwifi), and restart my OS for wireless to be back on. I wouldn't call this update process swift. The current version of linux-firmware seems to be old (20240318.git3b128b60-0ubuntu2.2). Maybe an update would prevent this problem from occurring to more users?
