I have my xbox 360 hooked up to my laptop and my IP address says fail. I try looking on my computer for a gateway address for the 360 and I can not find it. It is wried I just was on it about 4 days ago. Thank you for your time.

Answer depends on your configuration:Are you using Internet Connection Sharing, or did you simply bridge your network connections?Is the laptop connected directly to the internet, or does it connect to a router?Very helpful would be if you could post the output of ipconfig /all from a command prompt on that laptop.To do this: Open a command prompt (Start > type cmd into the searchbox > <enter>)Type ipconfig /all <enter>Once it's done processing, right-click anywhere in the command window > select all > <enter>Contents are now copied to the Clipboard; simply paste (via right-click > paste; or, <ctrl>+<V>) into your reply.-Chris[If this post helps to resolve your issue, please click the "Mark as Answer" or "Helpful" button at the top of this message.
