Been using Live perfectly for the last six months or so until now... Can connect to live to probs, but after about five minutes into a game, or just on the dashboard, the DSL light on my router flashes and the xbox disconnects.

BTbroadband, using a Voyager 200 router...

Coincedence or not, I don't know. But my PGR2 profile has become corruputed and won't load. Created a new one and it's fine (gotta buy all those cars and do all the tests again!! ) Wonder if anything else got corrupted?

Any ideas before I call microsoft/bt?

 

This what MS recommend . . .

Router & MTU Fixes--"Xbox Live is not responding" error message

The first step is to make sure your computer, modem, router and Xbox are connected correctly.

Go to the dashboard and run the troubleshooter from the Network Settings menu (select Connect and hit the A button).
You will see 4 green circles, indicating that everything is connected successfully (4th test shows "Connected to Xbox Live").
After the 4 tests complete, to see the diagnostic screen select the Y button.
If the diagnostic screen shows zero upload speed, zero download speed and 100% packet loss, your router might require additional configuration.
The next step is to find out is your router is listed on the Xbox Live Routers and Modems web page in either the "Use These Routers with Xbox Live" or "Use These Routers with Workarounds" sections. If your router is listed in one of the sections, click the links and follow the instructions to configure your router correctly.



Finally, you might also have to configure the MTU (Maximum Transmission Unit) setting of your router. On the administrative page of your router (or another admin tool) change the MTU size to 1365 or higher. You can find instructions for accessing the administrative pages for some routers by clicking here.

 

Been there, tried that. The only thing I couldn't find was MTU settings for the router. I've performed a factory reset and upgraded the firmware on the router, and still have the same problems. Thanks anyway...
