Troubleshooting Wi-Fi Connection
The following terminology is used in this troubleshooting section:
• Received Signal Strength Indication (RSSI). This is an indication of the signal
strength of the Wi-Fi router being received by the scanning device (i.e., smart
phone). Therefore, the higher the RSSI number (or less negative in some
devices), the stronger the signal.
• Wireless networks supported by this system are:
» 802.11b is 2.4Ghz band (max 11 Mbit/s)
» 802.11g is 2.4Ghz band (max 54 Mbit/s)
» 802.11n is 2.4Ghz band (max 130 Mbit/s)
• Internet Protocol Address (IP address). This is an address assigned by your
home router for each network device (e.g., computer, printer, thermostat).
Electromagnetic Interference Causing Poor Connectivity: Locate the Smart
Hub and router away from other devices that could possibility interfere with wireless
communications. Some examples of other devices that could interfere are:
• Microwave ovens
• Wireless cameras
• Portable phones and bases
• Baby monitors
• Wireless speakers
• Bluetooth devices
• Garage door openers
• Neighbor’s wireless devices
To eliminate a possible source of interference, temporally disable any devices and
see if Wi-Fi performance has improved.
Received Signal Strength Indication (RSSI)
The ideal signal strength range for the thermostat is -1 to -69 RSSI. The signal
strength can be viewed from the thermostat interface.
1. Press NETWORK SETTINGS; this screen shows a graphical view of buttons
representing OPEN and SECURE wireless networks, along with button for
adding a network.
2. Select the access point that has already been established and connected.
When selecting the info icon, a screen will appear which will display an option
to forget the network and IP address assigned to the thermostat by your router,
sub-net mask, router, DNS and RSSI. If the RSSI signal strength is anywhere
between -9 to -69, then the signal strength is sufcient. If outside this range,
then either relocate the router closer to the thermostat, add a repeater, or move
the Smart Hub. Adjusting antenna on router and/or Smart Hub may resolve the
issue.
