My girlfriend has a Macbook running Leopard and using AT&T DSL. She's able to connect to the internet by plugging into the included modem/wireless router via ethernet, but is unable to connect via wireless. It says that she is authenticated, but not connected. I'm able to connect to the internet perfectly fine using my iBook running Tiger. Her network is WEP encrypted and we're typing the password in correctly. I'm not quite sure what's going on here. Any help would be greatly appreciated. Thanks!
