Other Problems

If you are unable to fix problems with the 802.11b and 11g AP Card using 
the suggestions in this chapter, you may want to try resetting the AP to 
factory default settings.

On the 520wl Access Point hold the RESET button down for 5 
seconds.

Turn the power off and back on again to reboot the Access Point.

In some cases you may need to reboot your computer or clients as 
well.

Check the documentation that came with the client wireless cards 
for other troubleshooting procedures for those cards.

If you are still having problems with the 802.11b and 11g AP Card and you 
have not been able to fix them with the Troubleshooting suggestions from 
this booklet, please refer to the more detailed instructions in the Trouble-
shooting chapter of the 

HP 520wl User Guide
