CHAPTER 7: System Troubleshooting
Corrective Action
1. Is the power cord properly connec-
ted to the unit and the power outlet?
2. If the cord is properly connected,
replace the power supply.
1. Verify power to units (Access Point
and Station Adapter/Workstation
Bridge).
2. Verify that all units in the network
have the same ESSID as the Access
Point (ESSID must be identical in all
units in the network).
3. Verify wireless link:
• Set the Access Point and the unit
(Station Adapter or Workgroup Bridge)
side by side.
• Power on each unit and see if a
wireless link is established (even
models LW0055A through LW0058A
without their external antennas should
establish a link if placed side by side
with the Access Point).
• If the units fail to associate, reset
units to factory-default values (see
Section 3.4.5). The units should now
establish a wireless link.
