i had followed the link to configure radius server for wifi authentication. now the problem i m facing in this regard is when ever i tried to connect the client to the radius server. I got prompt for user-name and password at client end. As i enter the details it sends Access-Request to the server. Server on receiving this sends back access-challenge request to client and after that there is a loop of access-request and access-challenge packets between client and server. When i see the status at client site it says that it is trying to authenticate .i had to manually cancel the authentication process. The problem is that client didn't receive access-accept or access-reject in my case. kindly help me in this regard.
