I brought my macbook over to my friend's house the other day, and when I brought it back to my dorm I am not able to connect to the internet anymore. When I open up the Network, this is the message that is available: "Airport is connected to the network NIUWireless. Airport has a self-assigned IP Address and may not be able to connect to the internet." Any suggestions? I have tried turning off airport and just connecting via ethernet but even that will not work. All help appreciated, thank you.
