Question

I've got an xbox 360 and i tried to connect to xbox live,and it says the IP adress is confirmed,but when it gets to the DNS it says failed,I've got a Speedtouch modem and a dynamode router,and i've tried resetting it,but it still says dns failed.

Does anyone know what i could do to to make it work,and i've tried typing the dns maually but it still fails.

Answer 1

Are you sure you didn't get yourself banned from xbox live? Also the dns might not be working because it does not match what it should be. I assume this worked before something happened right?

Answer 2

Unplug everything that connects to the internet (e.g. the modem, the xbox) and make sure they both turn off. Wait for 5 minutes. Then plug them both back in and see if it connects.
