Ring Doorbell Pro abruptly goes offline - HARD

Have had a Video Doorbell Pro in fine working order, hardwired on a constant-live circuit, connected to a wifi signal (-66 RSSI, is typical), fully functional for well over a year. Goes offline HARD all of a sudden. Won't reconnect to network, no changes made to network and power has been stable. Health status showed as "good", 48 hours ago, but still shows "good" today, even though it is offline. Had to reconnect to the network using the side button on the inside. My concern: reliability. How can I trust Ring devices when they just seem to go braindead for no clear reason, entirely at random. Since I did a reconnect, it is working fine once again, but the fact that it just dropped out entirely gives me serious concerns.
