The logs clearly indicate that the authentication is failing. Which RADIUS server are you using? And what type of EAP authentication are you using? Has the user database been created on the Radius server? For instructions on configuring WPA on the AP read the document available at http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_example09186a00801c40b6.shtml

I have the same problem as the person above, but this doesn't seem to be a RADIUS server issue. The client will associate and authenticate when using Windows to configure the card, but using the Intel PROSet utility, it fails. Just looking for suggestions on what else to debug on the AP side. We are migrating to WPA2/PEAP with our prefered method being clients use Windows to configure the connection, but I know there are going to be those that "have" to use the utility.

If you're using Intel clients, update the drivers and the utility to the latest versions. Older versions are very unstable.
