Why is my XBOX 360 not detecting my internet connection?

[236]

It was perfectly fine. Then I couldn't connect to the Internet. It isn't detecting ANY network at all. Please help?

Check all the cables, try rebooting your router. Else throw your XBox in the trash or send it to get repaired.
a better alternative to throwing it in the trash is selling it on eBay or Craigslist.

If you're using wireless then try going into your console settings and reconnecting your wireless connection.
