The wireless enviroment consist of 30 cisco aironet 1210 access points, cisco wlse and cisco acs with ads authentification.
Since the last ios upgrade to version 12.3.8 on the aironet access points i have problems on some access points with the rooming from one ap to another.
On some AP the client authenticate correctly to the access point but can't renew his ip-adress and get data from the network. I thought it was a problem with the ios upgrade so i restore the old config and the old firmware but the problem remained exist.
The client use TKIP as data encryption and LEAP as server based authentification. when the client connects to some of my "problem" access points the server based authentification switch to NONE.
Has anybody an idea what i can do to solve my problem?
