In the near future, perhaps a few weeks, the CS Wireless network will be replaced by the campus run Moobilenet.
When you no longer find the CS Wireless network is available, you should see that "moobilenetx" is available. This will ask for your campus ID and Kerberos password.
Note the x in the moobilenetx, using that one, instead of mooblienet, will mean you have to enter your password fewer times.
Also available, for you and your guests, is Eduroam. Find more about Eduroam
