4. SYSTEM TROUBLESHOOTING
The following troubleshooting guide provides answers to some of the more
common problems that may occur when installing and using the D-Link Air Premier
DWL-1800. If problems not mentioned in this guide should arise, checking the
Ethernet and WLAN counters may help (see Section 3.2.1.3.4). If the problem
persists, please feel free to contact your local distributor or the D-Link Technical
Support Department.
4.1 Troubleshooting Guide
Problem and
Indication
No power to unit.
Power LED is off.
Failure to establish
wireless link.
WIRELESS LINK
LED is off and unit
resets every few
minutes.
Possible Cause
Power cord is not properly
connected.
1. Power supply to units
may be faulty
2. The DWL-1800R units
may not have the same
ESSID as the
DWL-1800B.
Corrective Action
Verify power cord is properly connected to
the DWL-1800 unit and to the power outlet.
1. Verify power to units.
2. Verify that all units in the network have
the same ESSID (ESSID must be identical
in all units in the WLAN; the ESSID is case
sensitive). Check that the units are on the
same channel.
3. Verify wireless link
Set DWL-1800B and
DWL-1800R units side by side.
Power on each unit and see if a
wireless link is established (even
"D" models without their external
antennas should establish a link if
placed side by side).
If the units fail to associate, reset
units to factory default values (see
Section 3.4). The units should
now establish a wireless link.
