To get your system up and running as quickly as possible, a modem connection to Xbox LIVE is your best bet. Like the name suggests, this method connects your Xbox 360 console directly to your modem or gateway. It's perfect if all you want to do online is play games.

If, however, you want to share your Internet connection with your PC while playing on Xbox LIVE, choose an alternate connection type:

• If your Internet service provider (ISP) provided you with a gateway (which combines a modem and a wireless router), you can share your Internet connection using a Gateway Connection.
• If your ISP provided you with a stand-alone modem, you can purchase a router and use a Router Connection to share Internet service between your Xbox 360 system, your PC, and other devices in your home.
• If you have a USB or internal PCI modem, choose a Windows ICS Connection.

Required Hardware for a Modem Connection

One Ethernet cable (supplied with the Xbox 360 video game and entertainment system; not included with the Xbox 360 Core system).

Make a modem connection to Xbox LIVE

1. Turn off your Xbox 360 console and your cable/DSL modem before connecting any cables. Unplug your modem from power to turn it off.
2. Connect one end of the Ethernet cable to the Ethernet port on your modem and the other end to the Ethernet port on the back of your Xbox 360 console.

3. Turn on your modem.
4. Turn on your Xbox 360 console and sign in with your profile.

If you're unable to connect to Xbox LIVE, you can try to diagnose the problem right on your console. Go to My Xbox and open System Settings, then select Network Settings, Test Xbox LIVE Connection.
