Symptoms/Cause
Remedy
Link LEDs on LEX unit
and REX unit are off.
Cause:
There is no wireless
connection between the
LEX unit and the REX
unit because:
a) The units are too far
apart or there are
too many
obstructions
between them.
b) There is too much
Radio Interference.
c) The WiRanger is
not configured
correctly.
d) The WiRanger is
malfunctioning.
Move the LEX unit and REX unit together so that
they are about 1 meter apart (3’) and power both
units. Confirm that they can establish a radio link.
If the WiRanger can establish wireless
communications at short range:
1. The original LEX unit and REX unit placement
is too far apart. Move the units to physically
closer positions that have fewer obstacles in
the way (walls, ceilings, etc).
2. And/or, there is excessive Radio Interference
on the 802.11g Radio Channel.
3. Using standard Wireless Networking software,
confirm if there are any other 802.11g radio
networks operating on or near the same
channel as the WiRanger. (Note you can
determine the current WiRanger Radio
Channel using the procedure on Page 9.)
4. Configure all conflicting 802.11g products so
that they use evenly separated Radio
Channels. Optimal separation is five
channels, so channels 1, 6, and 11 will
provide the least interference between
themselves.
If the WiRanger cannot establish wireless
communications at short range:
1. Confirm that the Radio Antennas are properly
secured to the antenna connectors of the
WiRanger.
2. Confirm the Radio Channels of the LEX unit
and the REX unit as described on Page 9.
3. If the LEX unit and the REX unit are not
configured with the same Radio Channels,
then set both units to the same channel as
described on Page 10.
4. If both units are already configured to the
same Radio Channel, then attempt the Pairing
Procedure described on Page 12.
5. If the above procedures cannot establish
wireless communications, then contact
Technical Support for further assistance (see
page 20).
