This seems straight forward. 4400 controllers with 1242 access points. The clients are a mix of windows CE devices and "dumb" wireless serial devices. The WLAN is configured as WPA1/WPA2 on the controller and are authenticated via PEAP/RADIUS. Encryption is AES.

The controller/WCS server has this message when a client has trouble, rebooting the client resolves it. "The WEP key configured at the station may be wrong." These messages occur about every few minutes with 85 clients.

Only thing I can think of there is some kind of key rotation problem. Any ideas or why I'm getting messages about WEP?

Thanks in advance.
