CHAPTER 18
WI-FI NETWORK TROUBLESHOOTING GUIDE
Any wireless system consists of two or more Wi-Fi transceivers and a radio propagation path
(Radio Path). Problems encountered can be any of the following.
Wi-Fi
communications are
inexistent or
intermittent
Presence of a low power
jammer
If the low power jammer is close to the
transceiver antenna, move low power jammer
(PC, telephone, etc.) at least 6.5 feet (2 m) away
from transceiver antenna.
Change the Wi-Fi channel on the router. Use a
Wi-Fi surveying or Wi-Fi stumbling tool on a
laptop computer to identify unused Wi-Fi
channels that may provide a better interference-
free radio path.
Move the ECLYPSE Wi-Fi Adapter’s position
where it has a clear line of sight to the router.
Move the wireless router’s position. Try moving
the router to the center of the room where it has a
clear line of site to each wireless device.
Presence of a high
power jammer
Remove high power jammer if possible. If not,
you will have to accept strong range reduction or
add another wireless router closer to the
controller(s).
Use a wired Ethernet connection to the controller.
Defective ECLYPSE Wi-
Fi Adapter
Exchange the wireless dongle with another
ECLYPSE Wi-Fi Adapter. If the dongle is found to
be defective, replace the dongle.
The maximum wireless
operating range has
been exceeded
Add another wireless router closer to the
controller(s).
The controller has a
known technical issue
Upgrade the controller’s firmware. See Firmware
Update on page 84.
The ECLYPSE Wi-Fi
Adapter has been
tested functional and
there is no jammer in
the field to interfere
with the signal.
Radio signal path might
be obstructed
If a new screening or metal separation wall has
been installed since the network was set up, try
moving the receiver to see if the issue is
corrected.
Router may have a
known technical issue
Upgrade the router’s firmware. See the
manufacturer’s Website.
