Choose a direct connection if you want the easiest way to set up and play and you don't want to
share your Internet connection with your PC (or other device).
To set up a direct connection:
1. Connect one end of an Ethernet cable to the Ethernet port on your high-speed modem and the
other end to the Ethernet port on the back of your console.
2. Follow the on-screen instructions. You may need to enter information provided by your ISP in the
System area of the Xbox Dashboard.
Router Connection
Choose a router connection if you want to share your Internet connection with your PC (or other
device), your high-speed modem supports an Ethernet connection, and you want to be able to play
on Xbox Live whether your PC is on or off.
To set up a router connection:
1. Connect one end of an Ethernet cable to the Ethernet port on your high-speed modem and the
other end to the WAN or Uplink port on your router.
2. Connect one end of an Ethernet cable to an Ethernet LAN port on your router and the other end to
the Ethernet port on your PC (or other device).
3. Connect one end of an Ethernet cable to an Ethernet LAN port on your router and the other end to
the Ethernet port on the back of your console.
NOTE
Some modems and devices may require a network hub instead of a router.
