Hi

Are you saying that your Xbox 360S says "To connect to a wireless network connect a wireless adapter"? If so try this:-

Here you find more info about setting it up:

I'm sorry that you're having trouble with your Xbox 360 wireless adapter. A flashing green light indicates that the adapter is attempting to connect to a wireless network. When you try to connect to your wireless network, does the console prompt you to connect
an Xbox 360 Wireless Networking Adapter, or does it recognize the adapter but display no wireless networks in the list?

You might need to change your wireless router settings. Here are some things you should know:

Xbox 360 S console: The Xbox 360 S console’s built-in Wi-Fi uses the 2.4 gigahertz (GHz) frequency band. If your router is broadcasting using another frequency, your Xbox 360 S console cannot connect to your wireless network. Check your router documentation
to find out how to set your router to broadcast at 2.4 GHz. If you want to connect using the 5 GHz frequency band, you will need to add the black Xbox 360 Wireless N Networking Adapter to your Xbox 360 S console.

Xbox 360 S console and black adapter: The Xbox 360 S console and the black Xbox 360 Wireless N Networking Adapter cannot use the 802.11n wireless protocol in combination with WEP or WPA TKIP encryption. If your router requires WEP or WPA encryption, your
console will try to connect to your wireless network using a slower wireless protocol such as 802.11b, 802.11g, or 802.11a.

Use WPA2 if possible: The best wireless encryption to use with your Xbox 360 console is WPA2 with AES encryption.

Wireless N router and a gray adapter: If you have an 802.11n or N type router and a gray Xbox 360 Wireless G Networking Adapter, configure your N type router to use a mixed mode; broadcast using a combination of wireless standard N and either B, G, or A.
