So I just moved into a new apartment. I've got an ethernet cable plugged into my AirPort Extreme, and I'm using my MacBook Pro to connect, and it works good for a while, then it just stops. I've also got an iBook, which is connected wirelessly, and it doesn't have the problem. I've got Leopard, and the iBook has Tiger, but I don't think that would change how it connects. Has anyone ever had this problem before?
