9 months old 3rd Gen Nest thermostat disconnected from WiFi and will NOT reconnect

[Timm2ee]

Nest thermostat disconnected from WiFi after 9 months of functioning perfectly and will not reconnect.  I have tried every troubleshooting suggestion reset, factory reset, power reset, router resets. No other nest devices in hose are affected. It simply no longer see's my router.

Hey Timm2ee, 

Thanks for reaching out to the Google Nest Community and for trying those steps already. 

A few questions — what type of Nest thermostat is this? If it worked before on this same network, were there recent changes made on your WiFi network, the actual thermostat or on the account it is set up on? Also, are you getting a specific message or code when attempting to connect it to any network?

Best,

Hey there, 

Checking back in — how's your thermostat now? Still need help with it?
