My wifi also just randomly stopped working a few weeks ago. Contacted
nest and Google, but obviously I'm past the 2 year warranty and waiting
for Google to get back to me with the holidays going on. I'd be
surprised if they replace mine out of warran...
Mine is a nest learning 3rd gen. Lost wifi but will work manually,
however it will continue heating/cooling past set temp and the battery
doesn't want to stay charged anymore.
