Xbox 360 S console not detecting wireless network

Hi, if you go to settings/ system settings/ network on the Xbox

Select your network in the list there, then select Configure network and then select Additional settings.

You'll see the Restore to factory defaults option, select that and then power the Xbox off and on again and try the connection again.

What often happens is when you've used the Xbox on another network it tends to keep the old settings and this should clear those out.

Check your routers™s wireless settings

You might need to change your wireless router settings. Here are some things you should know:•Xbox 360 S console: The Xbox 360 S consoles™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.

Hi Hali B, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem. Follow the instructions below for a solution.

If the console cannot detect your wireless network, first check if the console detects any wireless networks:
Press the Xbox  button to open the guide.
Select Profile & system > Settings > General > Network settings.
Select Set up wireless network.

A detected wireless network is displayed in What is yours?
If your console detects other wireless networks but not yours, see:
Troubleshoot a wireless network connection

If the console does not detect any wireless networks, continue with the troubleshooting steps below.

Try restarting the console first:
Press and hold the Xbox button  in the center of the controller to open the power center.
Select Restart console.
Select Restart.

When your console restarts, return to the Network Settings screen and select Set up wireless network to see which wireless networks your console detects:
If your wireless network is displayed in What's yours?, select the network to continue with connection setup.

If your console now detects other wireless networks but not yours, see:
Troubleshoot a wireless network connection
If your console still cannot detect any wireless networks, continue with the troubleshooting steps below.

To determine if the problem may be with the wireless network, check if other wireless devices (computers, phones, televisions, or other game consoles) can detect your wireless network.

If no other device can detect your wireless network, the problem lies with your network hardware. Consultation:
Troubleshoot a wireless network connection
If other devices detect your wireless network, but your Xbox console cannot, there may be a problem with the internal network adapter, and your console may need to be repaired.

Select Profile & system > Settings > General > Network settings.
