Xbox live to pc

Hello, I am writing because I can not connect my xbox 360 to my pc which is connected to the modem through a netgear DG834G key wifi (netgear wg111v3), I connected my xbox360 to my PC with the cable provided with the console thus far no problem. Connection Sharing, I read it falait networks create a bridge between the LAN and wireless networks but I'm doing a bridge I can not connect to internet and I can not even go to live. I come here to have some kind of detailed tutorial to help me thank you very much!
I am under windows XP.

You can also use the Xbox to connect to computers on your home network. If you have a Media Center PC and you connect your Xbox to your network, you can bring your recorded TV, videos, and music to your Xbox. That means you can watch TV on your Xbox, even if you don't have a cable connection in the room. If you have an original Xbox, you'll need the Media Center Extender for Xbox. Xbox 360 includes everything you need to connect to Media Center or to any Windows XP computer.

Microsoft Windows Internet Connection Sharing (ICS) uses your PC to share one Internet connection with multiple devices, including your Xbox 360 video game and entertainment system.

Use Windows ICS to set up your PC as a host through which your Xbox 360 system can access the Internet. ICS essentially lets you use your PC like a router, which is definitely convenient—but it requires that you turn on your PC when you want to play games on Xbox LIVE.

Xbox LIVE access through Windows ICS works with the Windows Vista, Windows XP, Windows Me, Windows 2000 Professional, and Windows 98SE operating systems.

You need to use a Windows ICS connection (rather than a router or gateway connection) to access Xbox LIVE in either of these scenarios instead of a traditional Ethernet connection to a stand-alone router, gateway, or modem.

1. You're using a USB connection to a stand-alone modem for your cable or DSL high-speed Internet access.
2. You're using your PC's internal modem for your cable or DSL high-speed Internet access.

Please see the page appropriate to your connection.

If you will not be using one of these connections to access Xbox LIVE, choose a router connection , a gateway connection , or a direct modem connection .
