I'm trying to share my macbook's internet connection received via airport to an xbox via the ethernet. Here are the instructions: http://www.joystiq.com/2006/07/17/how-to-share-your-macs-internet-connection-with-your-xbox/ The problem I'm having though is turning internet sharing on. I go to system preferences and select internet sharing from airport and then place a tick in the Ethernet option, yet it still comes up that its turned off with a red light next to it. I have entered my password etc. Any ideas?
