So I've been having some connectivity issues with the wireless network at my school with my snow leopard macbook. I can connect to the actual network but when I do it says that "airport has a self assigned ip address and cannot connect to the internet." I've googled around for this and it seems many have ahd the problem but nearly everything dates back to around 2004 in the ibook days and there never seems to be any kind of specific fix for it. Obviously I cannot reset the schools router and I never have this problem at home, only at school. Anyone have any fix for this or where to start?
