We are having a problem with Clean Access, our new Cisco Wireless lan Controller and some ( not All) students that connect in dorms that are still on our old ATM network equipment. They enter their credentials and click login and it appears to hang. They get assigned a Temporary Role. I see the entry in the CA log but they do no show up in the CA reports. They never get a sucessful screen or a tempoary access screen. Some student work just fine. This is only those using wireless. We have the dorms wired and they pass through clean access ok. WE have the same dorms using Cisco 1010 AP and a 4400 WLC , we've upgraded CA from 3.5.7 to 4.0. I've had several CCie's out to campus and they are at a loss. Any one encounter anthing like this?
