Ring stick up Cam shutter video good rssi

Have a Stick up cam (mounted in my garage wall) and it’s relatively close to my router. But the video shutters ,freezes randomly. Only support pages I can find talk about having poor WiFi connection. But my Rssi for that device is -56, which is good-excellent. Have tried restarting and erasing the cam and repairing. And ideas on what would cause this? Or do you think it’s a replacement kind of scenario. Will post a example video on what I am talking about later, currently on cellular.
