ESTABLISHING A WI-FI CONNECTIONS TO A HIDDEN
NETWORK
1. When connecting to a hidden network, press the add new
network icon to continue. Enter the network name
(SSID). If security encryption is enabled, then press the
security is none icon. Select either WEP, WPA or WPA2.
2. Using the on-screen keyboard, enter the password
(security key). If the network name or security key
combination is incorrect or incorrectly type, and access to
the specified network failed, a message will alert you to
retry.
3. If connection is successful the screen will return to the
available networks screens. The network successfully
connected will be listed and shown as connected as
exampled in figure 29.
Method 2 — Connection Status Method
1. Press connection status; this screen shows a graphical
view of the current connection status.
2. Select the router icon to choose the desire W-Fi network.
When selecting a:
• unsecured connection a screen will appear with two
options, connect and router info. Press connect to
continue.
• secured connection a screen will appear requesting
the Wi-Fi network password (security key). There are
two options to select from which are connect and
router info. Using the on-screen keyboard, enter the

Troubleshooting Wi-Fi Connection

The following terminology is used in this troubleshooting
section:
•
Router Signal Strength (RSSI). RSSI 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.
•
802.11a, g and n are wireless networking specification
that extends throughput up to 130mbps using the 2.4 GHz
band.
•
Internet Protocol Address (IP address). This is a
numerical label assigned to each device (e.g., computer,
printer, thermostat) participating in a computer network
that uses the Internet Protocol for communication. An IP
address serves two principal functions: host or network
interface identification and location addressing.
Electromagnetic Interference Causing Poor
Locate both 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.

The ideal signal strength range for the iComfort Wi-Fi
thermostat is -1 to -69 RSSI. The signal strength can be
viewed from the thermostat interface. Use steps 1
1. Press NETWORK SETTINGS; this screen shows a
graphical view of buttons representing Wi-Fi options
OPEN and SECURE wireless networks and a button for
adding a network.
