I am having trouble connecting to the internet through the airport on my g4 powerbook. It was working fine yesterday and then I put my mac to sleep. When I woke it up it wouldn't connect. The status says that it's connected to the router and the router is working fine because my friends ibook's airport is working and my powerbook works with the router when I have it hooked up via ethernet cable. I think it's definitely a problem on my end. I've tried turning the airport on and off to no success. I also tried to ping a website and there were no sucesses out of the ten I sent. Anyone have a clue to what is going on? thanks
