Hi Carl,
first of all: This question might be better placed in the Forum "Wireless - Mobility -> General".
Ok, now for me.
Your Environment:
1. You have a WLC (2000, 4400 or what)
2. What kind of AP
3. The Aironet cards are PCI CB21
The setup of the APs or WLC:
- Open authentication
- PSK
- EAP
Your event ID occurs e.g. when the NIC does have a network link but no network access.
Lets assume you have a WPA-PSK setup. If your PSK password is set to a wrong value in Windows you will get this message.
In wired environments i have seen this failure when a switchport failed or the NIC had a problem.
Did the APs ever run with the WLC before or is all of the hardware new?
Have a check on the Switchports and cables from the APs to the WLC! Try a show interfaces on the switches.
Maybe there is something wrong!
On the WLC (4402 in my case) have a look on "Monitor -> Ports" and then follow the "View Stats" link.
Also have a look in "Management -> Tech Support -> AP Log"
Hope that gives you the right hint!
Best regards,
Frank
