Xbox wired connection when there is no ethernet cable plugged in (Solved)

I have tried that a few times b4

Hi,

Sounds like a hardware fault I'm afraid, is it still under warranty with your place of purchase or Microsoft?

It is a physical problem, I've seen it before

Hey there John!

As a "quick step" solution try reset Xbox network settings back to the defaults.

Note Before you reset the Xbox 360 console’s network settings, make sure that you write down the current settings in case you have to restore them later.

• Turn off your Xbox 360 console.
• Wireless connection only: Unplug the Xbox 360 Wireless Networking Adapter from the USB port (if applicable).
  
• Turn on your console.
• Press the Guide button on your controller, go to
  Settings, and then select
  System Settings.
• Select Network Settings.
• Select Wired Network or the name of your wireless network, if you are prompted to do so.
  
• Select Configure Network.
• On the Additional Settings tab, select
  Restore to Factory Defaults.

Try reset your old router.

Post back and let us know how it goes.

Problem solved. Unplugged the ethernet switch and re-checked all my wired connections again. When I plugged the Xbox back in, it worked.
