Any thoughts? Wireless users are experiencing random disconnects.

Sounds like the supplicant is not acking the EAPOL frame.  You would need to do a wireless sniff in the area, to make sure the frame is seen in the air from the AP, and from the cleint.

Side note, we have had some reported issues with clients that do not care for the BSSID if it starts with somethign other than 00:

In looking at the radius configuration again I notice that we have two servers defined. I looked through the logs and didn't see anything alarming, until I checked the secondary radius server. I was just told that the second radius server has been shutdown without notice.

I will remove that from the WLAN config later tonight.

Obvious question, but will ask it anyway, will this cause these errors?
