Why is my RTH8500WF WiFi Series WiFi Touchscreen Programmable Thermostat not connecting to WiFi, or losing WiFi connection frequently?
If you are unable to complete the connection process, attempt the following before proceeding:
Turn off mobile data. This allows the thermostat and mobile device to communicate via the same communication method and can help with the registration process.
Attempt to connect and register the thermostat to a mobile hotspot. This allows the registration data to bypass any network security that may be causing the connection failure. Once successfully registered, a WiFi Reset can be performed to move the thermostat to the home WiFi network.
Attempt to use an alternate mobile device – some mobile devices use security features that can disrupt the registration process.
WiFi Network Recommendations:
If you experience inability to connect, failure to register, or frequent WiFi signal loss, verify the following:
*You may need assistance from your Internet Service Provider to verify/ change some settings*
2.4GHz bandwidth Network (Simultaneous 2.4/5GHz networks that experience connectivity failure may require a separate dedicated 2.4GHz network to be calibrated)
Connect directly to the router signal – Not recommended for use with signal booster, satellites, or extenders.
Business Networks (Enterprise networks, guest networks, or networks that require logging in via a web page/portal) are not supported.
Gateways or Network switches can block communication and are not supported.
Recommended WPA2-AES Network Security Protocol
