I have recently installed Mac OS X Lion on my computer. Everything is working pretty much good, just crash once a day. BUT! I have a serious problem. The internet icon is gone. Trough the setup, I came to the page where it ask me "How Do You Want To Connect?" I couldn't choose ethernet (thats what I want) or any other. Just Mobile Modem and "This computer is not going to get on the internet".

Any ideas!?!?

I need answer ASAP! Please!
