Base Station won't connect to wifi

I've had my Ring alarm for about a month and have the base station in a room about 20 feet away from my wifi router. The connedtion has been rock solid. The other day, I switched my wifi router to an Xfinity Xfi Gateway and the Base Station connected right away, but around 2am the next morning, I got an alert saying it lost connection and was on cellular backup. The Xfi Gateway says it's still connected, and the wifi signal light on the Base Station is lit up. I have tried to reconnect the Base Station to my new wifi and it sees the SSID just fine but won't connect. I even brought it right next to the Xfi Gateway router and it still wouldn't connect. Other devices around the house all have strong and fast signal. I don't want to keep my base statiton in the same room as my router so I don't want to do an ethernet connection. And it seems that if I try to totally reset the base station I'm going to have to reconnect all my sensors. I really don't want to have to do that. Are there any tips for this situation? If my router is saying the base station is connected, and the wifi light on the base station is lit up, could the base station be bad?
