I have the same issue on receiving the WiFi signal with my ring battery operated camera. But it seems to come and go. I downloaded WiFi Signal Strength Meter for Android from the Play store. It works really well. I am right at the edge of my WiFi signal. It takes about a 50 % signal to maintain the connect but I still have times when it does't work. Oh, my coop is completely enclosed in 1/2 inch hardware cloth also.
