I have a MacBook and I'm being really nooby right now. I usually use it at school to take notes so I get wireless internet connection on campus. But my stupid question is, how can I get the internet connection from the modem I have for my home computer to work for my laptop? I am not trying to share the internet connection between the two computers. I have already tried plugging in the modem cable into my laptop's ethernet jack and it still has not worked.
