I have been having trouble with getting online lately with my macbook via ethernet. I am plugged straight into the wall at my apartment, so there are no router issues (that I know of). When I try to get online, my ip comes up as 196.168.... and I cannot connect to the internet. However, when I boot up into bootcamp (vista), I am able to immediately get online through the same connection, and my ip appears to be different (10.1...). Any suggestions? I plan on going home this weekend (dont have my osx disc at school) and trying to reinstall the os to see if that fixes it.
