On the Xbox Home Screen, Navigate to Settings, go to System, Select Network Settings, Click on your Network setup. Now go to Configure network, Scroll right and click on Reset Network Settings to Factory defaults.
If the above solution doesn't work. You could try port forwarding, if your router allows for it. Xbox Live for the Xbox 360 requires the following ports to be opened: (For instructions, based on the make and model of your network device,
visit the link at the bottom of this post),
Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)
I your router doesn't support port forwarding or your issue is still isn't resolved, you could enable DMZ. (Refer to the link at the bottom of this link for instructions, based on the make and model of your network device)
If port forwarding or DMZ is enabled, it is best to turn UPNP off, if your Network device allows for it.
(Again, instructions can be found on the link at the bottom of this post based on the make and model of your network device).
Make sure you reboot your network equipment after editing the settings on the device.
You could also consider visiting the following link as this may also have useful fixes,
As a last resort, if you still are experiencing issues, you could reset your network device (eg. router, gateway). Most network equipment have a reset button physically on the back of the device. You can set the device back up with the CD
that came with it. If you don't have access to the CD, don't worry, you can get instructions on how to manually set it back up from the product's support webpage. You could also refer to the link at the bottom of this post for reference.
