Ok, so I bought a Penryn MBP not too long ago and haven't had a single problem with it. I've used ethernet cables and airport to connect to the internet and haven't had an issue. Until now. I moved into a new apartment 3 weeks ago and haven't been able to connect to the internet at all, ethernet or airport. In both cases it does the whole self-assigned IP address thing. My roommates Linux computer connects just fine. I've even went as far as to copy all of his TCP/IP settings and it's still not working for me. Does anybody know what it could be??? I had the ISP send somebody out here and they couldn't figure it out...then again they probably didn't do anything that I didn't do myself. Would maybe reinstalling the OS do anything for me? I can't figure this out.
