We want to allow sixth form students access to Public Wireless Network.

We have a secure Aruba public access network - internet only via a captive portal username and passphrase required. (duplicate logons also prevented) AUP also at point of logon.

Do you give wireless passphrase out to students - most have windows vista or 7 which just displays it anyway?

How frequently do you change this passphrase?

How do you do it?
