YHCGBTNHKM MY FREAKEN XBOX 360 WONT CONNECT TO XBOX LIVE WHEN I HAVE THE INTERNET CONNECTED.

Make sure that your xbox account is connected to a Xbox live membership. If so go sign out, and then sign back in and it should Work.

Depends if you have an Xbox Elite or an older Xbox 360?
If you have an Xbox Elite then there will be an in- built wireless, For older xbox 360's you will have to go and buy an Xbox wireless adapter.
If you go to settings, network settings, and select connect to xbox live via wireless then you will be prompted to input your security details for your Wireless and you should then be connected via wireless to xbox live.

Check your internet connection settings.
