Hi,
I hope you meant 802.1x and not 802.11x :-)
The AP configuration shows it is already on 802.1x authentication. Only config change I can suggest here is to change the encryption to AES rather than TKIP. TKIP is preferred for wpa and not sure wpa2.
If your radius server is configured properly then with the existing configuration you should be able to achieve Enterprise 802.1x authentication
Hope that helps
