My camera won’t connect for more than a couple minutes.

I have two cameras and one works just fine, but the other constantly disconnects. I haven’t been able to watch my baby for almost two weeks now. We have tried everything. Unplugging, repairing, unplugging and repairing after deleting and redone loading the app. Nothing is working. We have had issues with this camera for almost as long as we’ve had it but it has always been able to reconnect with some combination of the aforementioned until recently. Very frustrated and kind thinking this camera wasn’t worth the money.
