I’ve had similar problems but in my case, I have timers which power cycle the cable modem and another the main router at 4am separated by a minute . The Vue1 I have and the newer Vue2 as well don’t play nice after that. I eliminated both power cycle devices and the VUE will stay online. Otherwise doing a wifi setup on the VUE, bluetooth connects, it sees the wifi network I have with solid signal but never gets through to the emporia server. I plan to put things back a piece at a time and lengthen the off time to make sure the cable modem comes up cleanly first, before a power cycle of the router. (Can only power cycle the VUE at the breaker and usually that did not solve the problem anyways.
