The error message isn't really telling much to the user (hint hint) but I suspect this is by design: "iwlwifi: remove support for fw older than -17 and -22 FW versions older than -17 for 3160 and 7260 and older than -22 for newer NICs are not supported anymore. Don't load these versions and remove code that handles them." https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4b87e5af638b6056bd6c20b0954d09a5a58633be Adding luca. -- Kalle Valo
