Nest thermostat keeps going offline

Community Member

In similar post year, but no real resolution. I’ve had this thermostat for two years, almost 3, only recently has it started to drop Wi-Fi, usually after a day or two. I reset the thermostat network, I reset, my modem, I reconnect, it works for a day, and then it goes off-line again. The original batteries had a voltage of 3.0 something, so I replaced them with new batteries, the voltage is 3.2. It does have a C wire, and this is the first time I’ve had trouble with it in almost 3 years, any  advice?

Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
