I'm trying to connect to the wireless network at my college using OS X 10.6.2, however it's not as straight forward as usual... The network is hidden, although I know to 'Join other network' and type in the SSID of the network and then set the authentication method to WPA-Enterprise. However, this is where I run into a problem..

To connect, I need to 'configure encryption as AES', which I'm not sure how to do on OS X. Furthermore, after signing in with my college ID I am required to 'Use the domain name domain name' and 'configure your browser to use the college proxy servers http://example.example.net on port 123

Any help on this would be greatly appreciated as it's important that I log on to the network for work etc.

Thanks very much for your time.
