Ring Battery Doorbell Plus will not stay connected to Wi-Fi

The checks in more detail

If the battery is falling quickly and the signal is poor, the signal is probably the cause of the drain. Charge the pack, then deal with the signal, using Ring's guidance on poor video quality and on adjusting the router. Measure at the door itself, not at the router, because the doorbell is the farthest device in many homes and sits behind a door, a frame and sometimes a storm door.\n\nThe cheapest improvement is to move the router, which is not always possible. Next best is a Ring Chime Pro, a plug-in extender made for Ring devices, put in an outlet within a room or two of the door.

A mesh node or access point inside the porch or hall also works. Ring says the Battery Doorbell Plus joins the 2.4 GHz band, with 5 GHz where supported, so check how your router presents its bands. If the router uses one name for both and the doorbell has trouble, give the 2.4 GHz band its own name just for the set-up or reconnect. After a new router or password, use Change Wi-Fi Network in Device Health so that the doorbell takes the new details without the faceplate coming off. Avoid special characters in a password, which some set-ups handle badly.

Check that the router has free addresses and is not blocking new devices. Cold weather lowers both battery output and radio strength, so a doorbell that struggles in winter and recovers in spring is behaving normally for its batteries, and a charged spare helps. Do not climb a wet ladder to test. If the doorbell works near the router and fails at the door, the signal is the issue; if it fails beside the router, reset it and set it up again. Update the app, and contact Ring support if a good signal still gives poor results.
