In order for anyone to answer your question you will have to provide them with the full information they require. I would suggest you explain precisely how you have your 360 connected to the internet before you go any further, for example:
Do you have a router?
Are you connected by a network cable or using the wireless adapter from Microsoft?
Are other devices connected to your router and do they work fine?
I would suggest assuming you have the router set to DHCP (automatic IP assigning) and are plugging in by cable, you should do a reset on your network settings on the 360 as some settings get stuck and need a kick.
All of the above information is of course subject to this not being a troll and joke account wasting theirs and everyone elses time on here.
