Route was different a week ago, but we changed that thinking it was a
possible with no change.  Even with a direct route from modem(access
box)->switch->Games server (both ways) and directly back we still get the
problem.

I don't think this is the problem because the same machine drops that ISP
connection, dials the *other* local ISP, connects to the game server across
the net and doesn't get the delays.

We know where it is in the game and the effect it has on ping times and lag
and as inidicated above there is only one hop to trace over and it's
basically fine.

Is that a typo about "too much bandwidth" or can you expand on that please?
