Ok so the other day the comcast guy came and gave us a new router because our old belkin broke. Well the guy fixed all of our internet on our computers. So on my xbox it says the connection is fine. i tested it many times. so i go back to sign in and and it says i am signed into mesanger then it says so many friends are online. well the little xbox with the circle going around it stays on the market place, xobox live, and game screen. Then the circle goes away and signs me off. So i try again then it says my DNS failed the test. so i try the test again then it says my IP failed. So i try 1 more time and it says i have perfect connection. so i try to sign in and it does the same thing over and over again
. It's making me really really mad. I havent been able to play for a month now. PLease can anybody help me?
