Hi, I have a laptop with a MediaTek mt7921 wireless chip, and I'm getting disconnected from the AP every 10 minutes (PREV_AUTH_NOT_VALID). I've tried to disable aspm, without any noticeable improvements. The only relevant information to my problem I found on the mailing list was regarding a problem that could lead to the driver preventing wpa_supplicant from receiving EAPOL frames. I'm currently running a manually built kernel 5.17.0-0.rc3.20220208git555f3d7be91a on Fedora 35 (to toggle the requested CONFIG_MAC80211_ debugging build options). So far, I haven't seen anything suspicious from wpa_supplicant, which simply reacts to the event accordingly (from events NL80211_CMD_DEL_STATION then NL80211_CMD_DISASSOCIATE). -- lspci 03:00.0 Network controller: MEDIATEK Corp.
