I have a few cams and a few access points with the same SSID (not a mesh network). My experience is that the Wyze cam will attempt to connect to the AP with the strongest wifi signal, even if it has impaired WAN connectivity, so a camera can go down even if it is in range of a good AP. (Arguably, the AP should take itself offline if there is no backhaul, but that’s not generally the case.) It seems like a cam should cycle through the APs with the desired SSID until it can connect.
Maybe it already does this and I’m observing a different problem?
