Hello there im having a problem here with my Macbook Pro 13". i just completely emptied my hard drive and re-installed the Macos. When i was visiting my girl friend, and was trying to re-connect to her Wi-fi, it connected, but it said "self-assigned ip" and "no internet-acces". i then downloaded the updates through my Iphones shared internet connection. Thereafter i installed Windows 7 Ultimate through boot camp(Because off the game in-compatibility with games and macs). I tried to connect to the internet here, it connected without troubles. I am now using the windows boot camp to write this post. Btw. my Iphone is connected to her Wi-fi, her pc is too. my mac can connect to my Wi-fi at home, so as far as i see it must be the Router here. I was connected to her network before the re-installation of the OS without problems I have also checked if my Firewall was blocking me out, but found that it was disabled. I have googled my problem, but could not find a working fix. please ask if you need more information, and guide me how to get this information.
