Essential Cameras keep dropping off line daily or so after reset

[w7]

I have three essential spotlight cameras in outdoor locations that have worked fine for a year or so. Over the last couple of weeks one or two are dropping offline and needing to be reset, then a day or so later one or more of the three drop out again, repeatedly. Batteries are all above 50%. Not changes to any locations or the modem/router. Signal strength from gateway table looks okay.  I need some advice as I am tired of climbing up to reset these.

Start by bringing one closer to your router or hub. Also check for interference from any wireless device, probably near the router or hub, or something from your neighbors, such as a strong WiFi signal.
