E8 - WiFi Router Not Available.
Troubleshoot WiFi Router:
- Confirm signal strength by placing a mobile device next to the nJoy thermostat. If the wireless signal is non-existent or weak, then the wireless signal will need to be improved to the location of the nJoy thermostat by acquiring better WiFi equipment or a signal repeater. This may also be caused by other equipment or building materials causing signal interference.
- Confirm that the WiFi router is not overloaded, that it is not overheated, and that it is compatible with IEEE 802.11 b/g/n with a 2.4GHz channel open to devices(nJoy thermostat).
- Confirm the ISP (Internet Service Provider) is not experiencing an outage.
- Reboot the Router.
