Cisco AP1200 - no client association

Hi.. hoping someone can assist..

We have a few Cisco AP1200's that doesn't seem to be accepting any
connection from the clients.


Here's what I've discovered so far..
- event logs doesn't show any info or errors
- I can't see the AP in netstumbler
- running Radio Carrier Busy Test, it's showing 100% for all freq.


I've tried to reset the ap to factory default - still using VXWorks but

the default Tsunami SSID or anyting is not showing up in netstumbler.


I've upgraded to the latest version of IOS - same results - no results
-> no clients connect, no error or any info on event log (except once
in awhile there is a radio down/reset/up). Only difference is Carrier
busy is not 100% - all freq is in the 60-70% busy.


Eventhough carrier busy is high %, net stumbler is picking up only 1-2
APs using channels 1 or 11. I tried manually setting channel to 6 but
still no clients are connecting or netstumbler is not seeing the AP.


Any help would be greatly appreciated!


Thank you..
