I also had the problem of many disconnects after updating my wifi-card.
Diving deeper into it I discovered I deleted all SSIDs and by accident created new main SSID with PSK2+TKIP+AES encryption.
After changing that to PSK2+CCMP everything works again as expected.
@blbeczech82: What I’m curious about - do we have the option to set wpa_strict_rekey=1 somehow as it doesn’t seem to be set by default?
