Another question.

.

.

been having problems finding races on Forza recently.

.

.

Last night it crashed just when a race was meant to start.

then I couldn't get into any, just tried to join then said

"Game session full or no longer available"

Thing is, how do I know if it's a problem with my connection, ie my modem, ethernet cable, just plain slow, whatever.

.

.

or the recent, much talked about connection problems with xbox live?

All I know is the lights on my modem are flashing.
