Hi

My predecessors have setup wireless network using the following:
 
Cisco Aironet 1142 Wireless-N Lightweight Access Point and
Cisco 4400 Wireless LAN Controller  and
Window  2008  as a Radius server.

Please post me some documentation or tutorials as how this works /how to integrate  and configure these. Also how the clients gets authenticated and gets certificate from the Radius server .

Essentially, most configs end up with the ap dynamically receiving an IP address. In the dhcp scope the ip of the controller is given to the ap, or a dns entry can provide that info. The ap then registers with the controller, obtains a config, and all wireless connections get tunneled through the controller. The controller and the server have a simple radius relationship. If the server is handing out certificates, I cannot speak to that as it's beyond my expertise.

Hi

I looked at the certificates in the AD server   through GPMC
-Computer Configuration
-Windows settings
-Security settings
-Wireless network
 on the right pane -right click the properties-preffered networks
Edit - IEEE802.1X - settings - and View Certificate.

and  the certificates are valid and i can see the same valid certificate on the client as well.
and they are valid till 2030 and it looks like self signed. Is there any chance for the certificate to get corrupted?

Is there a way to test/diagonise if the Cisco 4400 WLC  controller is able to establish proper relationship with the Radius Server.

Thanks
