I was just watching a netflix movie and all was good. I got off and started to play COD4 I was customizing my weapons and went to find a match picked Team death match and it said connecting and it froze for about three minutes and then came back with not connected to Xbox Live. I then rebooted the console and still no luck. I then went to test Live connection and it said failed to log on to live and told me to reboot my Modem. After that it was good it even fixed a problem of long login in when the console first was started. I then played a match of COD4 and turned off the system to eat supper and went to start the console, it would not turn on with the controller. I had to push the power button on the console. Now everything works fine. Is my system about to go bad or was it a glitch?
