Instructions
1. Purchase either an Xbox 360 wireless adapter or an Ethernet cable if the Xbox 360 console is close enough to your wireless router to be connected via cable (see Resources below). Connect the male end of the wireless adapter into the female port located on the back of the console or plug one end of the Ethernet cable into the Ethernet port on the console.
2. Turn on the laptop and click the "Start" button. Click "Control Panel" and wait for a new window to appear. Double click the "Network And Sharing Center" icon.
3. Check the top-right side of the screen and find the name of your wireless network. Write down the name and then power on the Xbox 360 console. Scroll through the main menu options. Press the "X" button on the controller when you reach "Settings."
4. Choose "System Settings" and then choose "Network Settings." Scroll down to the text field and type in the network name you wrote down earlier. Press the "A" button on the controller to save the change.
5. Return to your laptop and navigate back to the Network and Sharing Center area. Click "View Computers and Devices" and then click on the icon for your laptop. Wait for your laptop to detect the Xbox 360 console and then click "Yes" when a window appears, asking if you want to connect to it.
Tips & Warnings
If your laptop is using an older version of the Microsoft Windows operating system, the "Network and Sharing Center" icon may instead just say "Network Center." Any music files you have saved in the "Music" folder of the Windows Media Player application will automatically stream from your laptop to the Xbox 360 console.
