Hello Everyone, I've had woes with Apple and my network for the last few years and I really don't know why. I randomly get the dreaded "self assigned IP address" and have no idea how to solve it. When I had my g4 powerbook running leopard, i tried all the tricks and nothing ever worked. My only solution has always been to reset the router. I got a new computer, macbook pro preinstalled with lion and again, i'm seeing the same problem. The problem with my solution of resetting the router just isn't plausible all the time because there are other people in my household who are on the computer (using windows 7) and cannot stop their workflow for a few minutes while the router is resetting, and than the issue becomes really problematic for me. From paying attention to it the last 3-4 years, I think the problem only occurs when the windows 7 computer is already connected to the internet and my MBP wasn't..and than I try to connect it. I sincerely appreciate any help at all, as this is just making my laptop to use a real pain. I am using a 13inch Early 2011 MBP running 10.7.1 I'm using a Buffalo Air station wireless G I'm on a WPA protection I'm more than glad to give any other details as I really just want this issue fixed.
