WAX630 in standalone mode keeps de-authing clients and stops broadcasting SSID occasionally

All day every day since a few days ago I am getting notifications of appliances and other devices going offline. I find the SSID is no longer broadcasting, or if it is broadcasting, connecting to it fails with no specific error. I have to reboot the AP to get things back online, but doing this 10+ times a day is not feasible. Need some help here. Anyone else experiencing something similar? This is having a serious effect as my security system cameras are connected over wifi and not hardwired, so I am losing periods of time in my recordings. If this goes bonkers late at night, I won't have any idea who broke in.
