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 Bands 802.11a, g and n. These are wireless networking standards
that extends bandwidth throughput up to 130mbps using the 2.4GHz 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 (especially those operating on 2.4GHz
frequency). Some examples of other devices that may 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 any connectivity issues.

Renaming System

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