Hello. I have recently changed my wifi network name and password and reconnected both of my Nest thermostats to the new network. One of the thermostats keeps disconnecting from the internet and going dark. When it turns back on, it won’t connect back to the internet without a forced reset (hold down 15 secs) then it reconnects just fine —- only to disconnect again in a few hours. It was working just fine before the change in the network name/pw. What’s causing this issue?
