Gen 2 doorbell continually going offline

I've had this doorbell since January. The power is hardwired (using the Ring power supply). It now barely stays online. It's connected to a wifi extender that's (at most) 4 feet away from it, but regularly goes offline, leaving the doorbell itself working and sounding, but not alerting anyone. It the current state, it's less than useless. There's no pattern to the times it goes offline, it just appears to do it when it feels like it. Any suggestions would be welcome, as otherwise it's coming out
