The new generation routers and phones are also equipped with the 5 Ghz wireless network activated and the devices connect automatically on this frequency. The thermostat cannot be connected to the 5 Ghz wireless network because it only works on the 2.4 Ghz wireless frequency. To configure the router and the 2.4 Ghz wireless network, call a specialist.
