Please make sure that your network name (SSID) is not hidden. If it is hidden you can scroll down the connections list until you find the “Other Network” option. Here you can manually enter the name and password of your WiFi Network. If your SSID is not hidden, your wireless radio might not be reaching Wiser Air. Please try to move the router as close as possible to the thermostat. Also, Wiser Air is only compatible with 2.4GHz wireless networks. If your WiFi is configured as a 5GHz network it will not show up on the network list. Please check your modem/router configuration to determine the status and settings of the network.
