A little heads up for Atheros AR9462 owners.   It seems that the latest kernel renders AR9462 (and maybe some other cards using ath9k module) WiFi close to unusable due to network connection being dropped continuously.   The problem seems to be not Arch-specific; there is an upstream report for this:  https://bugzilla.kernel.org/show_bug.cgi?id=215698   Upgrade with caution; keep old kernel package cached. Rolling back to linux-5.16.3 worked well for me.   Regards, Danila Kiver.
