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). So the higher the RSSI number (or less negative in some devices), the
stronger the signal.
• Wireless Bands 802.11a, g and n. These are wireless networking standards that
extends bandwidth throughput up to 130 Mbps using the 2.4 GHz band.
• 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
thermostat 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 sufficient. If outside this range,
then either relocate the router closer to the thermostat, add a repeater, or move
the Smart Hub. Adjusting antennas on router and/or Smart Hub may resolve
the issue.

Name

Renaming System

Selecting this option to name your system. There is also an option to unregistered
the system.

Unregistering the System

Using this feature will unregister the system from your consumer portal account if it
has already been registered to your account. This will only remove the system that
is currently being accessed.
NOTE: If you have multiple systems assigned to your account, only the system
you are working from will be removed.
