Hi everyone, I just got a MacBook for college, and I've only had it a few days. I used AirPort to connect to the internet, and it had been working. But then all of a sudden I was connected but it said..."AirPort has a self-assigned IP address and may not be able to connect to the internet." I am connected to my home computer, but I can't get on the internet. I've tried fixing a few things and everything seems to be fine. Why is it doing this? It did it last night and today it's doing it as well. I haven't set up my own internet yet, so maybe that's the problem-I've just been using other networks. But it was working fine yesterday, so I don't get it. Any help would be appreciated!
