Having the same issue with my indoor wired camera. It was working fine and now all of a sudden I noticed the camera has been offline for a while. My outdoor battery cameras are conected to the wifi fine. I've disconnected, reset, unplugged, tried to set up device again. You name it, I've tried it. Still not working. It says there's an issue with my wifi when I try to connect, but the speed appears fine and all other cameras are connected to the wifi fine.
