Why isn't my thermostat connecting to my WiFi router even though it is very close to the thermostat?

Please check a few steps first, in order to make sure that your router can be "seen" by your thermostat:

1. Your router is powered and broadcasting the WiFi signal in the 2.4GHz range.
2. Your thermostat is not in a place with poor signal from the router. For example, most homes have “dead spots” where WiFi signals are unreliable.
3. Your thermostat "sees" and connects to the home network, not a guest network. If you must connect to your guest network, you will need to unblock port 443 in the guest network firewall.

For more information on your WiFi settings, please see your user manual, after selecting your model from the list below:

9000 family and VisionPro	Lyric T family
6000 family	8000 family

If the thermostat still cannot connect your WiFi network, please reset your WiFi Connection, by following the instructions in this video.
