When you run "Test Xbox LIVE connection" what is the exact message that appears onscreen? Cannot connect to xbox live.
I've been playing Xbox live for around five months now with no problems at all. I've disconnected maybe 4 times in total, and I've never had a problem that couldn't be fixed by either restarting the console or troubleshooting, but this just baffles me. I'm connected to the internet, everything in my house can receive internet fine, and my xbox connects, but after 10~15minutes the game will lag, and then xbox live will disconnect. Upon attempted reconnection, it says it cannot resolve the names of the xbox live servers. This renders xbox live almost unusable to me, because it disconnects me in the middle of netflix or a call of duty match, and I lose all progress that I had earned.
An interesting side note is, when you restart the console while it's lagging (pre disconnection) it will connect to the internet for about 10 more minutes, before crashing. I don't know why it can identify the xbox servers, use them, and then just lose them? I've tried EVERY single troubleshooting option besides calling my ISP, which I'm about to do. It seems as though a few other people have been having this problem since around 5/21/11, and I was wondering if anyone had found a solution.
Thanks in advance,
