If you want to connect your XBOX to your ISP's Wi-Fi network, there is a simple way to do it. As shown in this video, the first step is to configure your laptop/PC to allow internet connection sharing. The XBOX already has an Ethernet cable bundled with it and so connecting it to your PC is easy. The next step is to properly configure the NAT settings on your PC. These may later affect certain XBOX live features. Finally, test your XBOX live connection using the inbuilt test on your gaming console. A point to remember is that this method only applies to the Windows Vista operating systems. The exact procedure may not apply to other Windows based operating systems.
