Hi, I bought my macbook in January 2008. I have had no problems up until recently. All of a sudden my airport started signing me out of my wireless network. I would sign back in, and there would be no problem. Then it started saying in the status bar in Safari..."connecting". I would have a full wireless signal, but no progress on the internet page would be completed. Most recently it has shown full wireless connection, and absolutely nothing can be pulled up on the internet. I can't use iChat, or connect to the iTunes store. It says that I should be able to get online, but I can't. Even after restarting AirPort and my computer...nothing works. I brought it into the apple store, and apparently nothing is wrong with it. What's going on?
