Soho goes into connection fits a few times a day

Hi, I got a new soho mk3 to replace my Go2 in my RV. Seems to work well, when it’s connected. But multiple times per day, I’ll get 10-20 notifications that alternate disconnected and connected. I’m using WiFi as WAN on 5GHz. I’ve tried 2 different AC791Ls and it does the same thing on both. Sometimes there is an alert mixed in with the connects/disconnects that says WPA response timeout.
Any thoughts?
Thanks!
Phil

Please disable 5GHz on Wifi AP to confirm this will help. Please find the screenshot below for better understanding.
