on my friend's new MBP, iChat will not logon when it's on wireless. It just hangs. Any special thing we hafta change, a setting or something? it happens on my gf's MBP too. very strange! a solution would be much appreciated 🙂
I doubt I can be of any real help, but it might help others who could help, if you could list what version you're running. In the menu bar> iChat> About iChat
Also, try going into iChat> Preferences> Accounts> Server Settings
