C On your computer, turning Wi-Fi off and then
back on will force the system to rescan for
available networks. Do you see the network your
thermostat is trying to connect to?
6. Power cycle the thermostat.
7. Keep cordless phones, microwaves and other
electrical equipment at least 3.5 feet (1m) away from
access point.
A Try moving your router closer to the device if
possible. If connection is improved, then there is
probably some interference. Must have signal
stronger than -70db (also, see Router Signal
Strength on page 3); anything less will have
signal losses or not connect at all.
B Adjust the direction of the router toward the
thermostat. Adjust the routers antenna. A signal
repeater may be needed.
8. Try changing channels on the access point and test
it out with one of your internet devices (i.e. laptop,
desktop). The IP address to the server from the stat
will be close to the same IP address from the
computer to the server (www.mycomfortsync.com).
COMPUTER CONNECTIONS:
A On Access Point, Login to configuration (usually
web based interface) > go to Wireless Settings
and select a different channel > Save settings.
B Devices cannot change Wi-Fi channel. It is set
only at the router.

C On the thermostat, disable, then re-enable the
Wi-Fi connection.
9. Antenna in thermostat is fixed and cannot be moved.
Location of your access point with respect to the
thermostat is very important.
10. Baby monitors, garage door openers and wireless
video cameras may create signal interference.
11. Check your encryption key (Password).
12. Double check and re-enter your WEP/WPA
encryption keys / pass-phrases (usually found on
the router). If set to WEP security, change to WPA
if allowed.
13. In your thermostat's wireless settings, verify that
your encryption key (password) is correct. There can
not be spaces at the end of the SSID or Password.
14. It is important to note that number of walls that the
signal must pass thru to reach the thermostat can be
an issue. (e.g. 4 indoor walls, or 1 outdoor wall + 2
indoor walls could mean a weak signal at the
thermostat).
15. The addition of a signal repeater or extender maybe
an option. (Desktop or wall outlet plug-in devices are
available online or at your local electronics stores in
price range $70 - $150).
16. If multiple routers are in the home make sure each
router has a different name.
