If it only happens when your internet goes out (and not other times) I wouldn’t expect beamforming to be the issue, but it is possible. If it is strictly when your internet goes down then I’d suspect it is just something in your setup where the cams get confused, they’re connected to wifi but can’t see the internet, and after a while give up trying to communicate with Wyze. In that case, bouncing your wifi (all of it) should take care of it as that will wake them up and force them to reconnect.
