This evening I have been trying to connect. I have already triwd all the basic troubleshooting steps and the same thing happens over and over. My Xbox 360 connects, but as soon as I try any activity (game, chat, etc.) the system freezes for about a minute. It will then come up and say Disconnected and take me to the diagnostics area. At that point I get a variation of messages. Sometimes it says network down, other times no internet, and a few times no Live. About half the time I get a message saying everything is OK and I can re-connect until I try to send a message or go to a game then I'm out again. Any suggestions are appreciated. By the way tomorrow I have an ISP service tech coming because of this issue as well as other connectivity issues lately.
