Troubleshooting
This chapter provides solutions to common problems that usually occur
during the installation and operation of the D-Link DWL-A520 Wireless
Network Adapter. Read the following descriptions if you are having problems.
If you cannot find an answer here, please contact an D-Link field application
engineer for assistance.
1. My computer does not recognize the D-Link CardBus reference
card.
Make sure the CardBus card is properly inserted into a 32-bit CardBus
slot. If Windows does not detect the hardware upon insertion of the card,
the system could have a previous D-Link NDIS driver installed. Remove
the old driver and try again.
2. The D-Link DWL-A520 Wireless Network Adapter does not work
properly after the driver is installed.
Re-insert the CardBus card into the slot. A beep should be heard if the
adapter is properly inserted. Go to Device Manager and make sure the
D-Link DWL-A520 Wireless Network Adapter exists under the network
adapters device node. If you see the yellow exclamation mark then there
are conflicting resources. In this case, make sure the computer system
has a free IRQ and make sure you have installed the proper driver.
Uninstall the driver, restart the system, and repeat the driver installation
steps if necessary.
3. Stations cannot associate in ad hoc mode.
Make sure the same service set identifier is specified for all stations that
need to join the same ad hoc network. Set up one station to establish a
BSS and wait briefly before setting up other stations. This prevents
several stations from trying to establish a BSS at the same time, which
can result in multiple singular BSSs being established, rather than a
single BSS with multiple stations associated to it.
