I'm at my wits end with this problem. I've tried searching this forum and the Internet, but can't seem to able to figure this out. The problem is, when, after everything (xbox, router, computer) has been turned off for the night I can connect to Live and download stuff. But after a few minutes (~5-10) I can't anymore. I don't change any settings, connect/disconnect any cables or devices, but my Live connection just dies. This same connection has worked before, I just plugged my Xbox in and away I went. I was at another house for about three months (nothing should have changed here where I am now), but now I have this problem. Any help, anyone?
What Country/State/Province do you live in? Finland
Modem brand & model number: Zyxel P-660H-D1
Network Connection Type: Wired
Things you have tried:
Is UPnP Enabled? Yes
Is NAT Type Open? I have forwarded (or so I think, ask for more info) the following ports: 53, 80, 88, 1863, 3074
Any Error Codes you encounter: None
What type of internet do you have? DSL
Who is your ISP(Internet Service Provider)? The phone company
After you run "Test Xbox LIVE connection" and click on "More info", what is the exact message shown on screen? ATM I don't get any errors, it just comes back to the "Available networks" screen and doesn't say anything. Neither the wireless or wired networks has the little ok-sign on the top right corner.
I have switched the ethernet-cables and ports around and my computer connects to the Internet just fine. I have been thinking that could my ethernet port on the Xbox have been damaged? But if so, why can I connect to Live for a short while and then my connection just fades away and could there be anything I can do to revive the port?
