Ring doorbell is disconnected from network. Last reported signal strength is good. Last reported voltage is good. Reboot router a couple of times. Tried to go through setup and that failed as well. It will not join the ring network. Tried this three times. I also turned the breaker on and off to reboot the doorbell. Also, the doorbell is about 20 feet from my wifi router. I did take one of my cams to the location of the doorbell and ran a speedtest. got about 180mbps down and almost 20mbps up. The doorbell has been working flawlessly for about 3 weeks up until a few hours ago.
