This is not chicken camera related, but WIFI.I had the same problem...my wifi connection was not strong enough from my house to stay connected to a camera in my coop. I tried a Wyze outdoor camera and it disconnected from the wifi every few hours so it was basically useless. I got a new router and STILL had the same problem with the Wyze.
I recently got the Tapo outdoor 2K QHD camera and it has stayed consistently connected to the wifi since I installed it this weekend! It has two antenna built in so it's able to keep a stronger wifi connection. I've only had it for a few days and it's already stayed connected longer than the Wyze. I think the Wyze's image quality was slightly better but the connection issues made me return it. I also think the Tapo was about half the cost of the Wyze.
My WIFI is from a different service provider than before. Lets just say,,,,, PLENTY OF HORSEPOWER NOW.
On my previous service, the WIFI signal was OK, but not GREAT.

I no longer need it, so it is idle in my drawer.
Wondering if you had one located somewhere between your Router, and exterior wall closest to your coop??,,, if your Wyze camera would have stayed connected?
