Requirements:

• Ethernet Cable(I used a different one, not crossover)
• A computer with an another connection(wifi, extra Ethernet port)

Steps:

• 1.First you have to manually assign the ip address for the card connected to the xbox.So go to Show all connections and right click the card. Then click properties. Select the properties and scroll down to tcip/ip.Then click properties. Enter an ip address that is similar to the other network that will soon be bridged. EX. if the connection to the internet to PC is =192.168.1.115,then Connection from xbox to pc=192.168.1.112.subnet should be 255.255.255.0.And the network address would be 192.168.1.1.
• 2.Connect both connections.Open up Network connection and highlight the two connections.And right click and choose bridge connections.
  3.Test your connection to see if it works.
