Certain routers can cause the Nest Learning Thermostat to intermittently disconnect from the Internet

The Nest Learning Thermostat needs to be connected to the Internet in order for you to access and control it from your Nest Account. There are some routers that’ll incorrectly disconnect the Nest Thermostat from the Internet after 30 minutes or less of inactivity.

Unfortunately, these routers don’t conform to the TCP/IP specifications around Network Address Translation (NAT) timeouts and are disconnecting the Nest Thermostat too soon.

Often, these issues have already been addressed by the router manufacturer in a firmware update. We recommend that you check the manufacturer's Web site to see if an update is available for your router.

Check here for our list of unsupported routers that may have this problem:
