    So here's the deal, my macbook pro can't connect to the internet via the airport express or directly to the ethernet all of a sudden. But the POS PC laptop I have connects just fine. I didn't do anything different one day I wake up and it acts like this. It recognizes the signal, connects to airport, gets a good IP, just can't connect to server. I've reset airport, I've deleted system preferences from the library folder, I've reinstalled the network, I've fiddled with every preference available and still nada. I'm at my wits end, and so is apple support apparently because they couldn't figure it out and said to reinstall OSX. It's so maddening b/c the cheapo, practical pc connects just fine and the pricey sexy mac doesn't. It really odd b/c sometimes after fiddling for a while I can load 1 and only 1 webpage and then it goes back to not working. Also I will run network diagnostics and it will say my internet is working even though their are still yellow circles next to internet and server. sometimes I get all green lights and it still doesn't work. I'm at a loss, any suggestions would be very appreciated. Thanks.

    Have you tried other browsers and apps if they would work?
