I remember experiencing something similar a long time ago, with an old
Linux box as the router, I think.  Unfortunately, I've forgotten the details.

Is wireless a part of the equation anywhere?  Could there be a frequency
interference that didn't happen with the other router?

If you leave something like top running in the window, does it eventually
die?  If it doesn't die, then it might be a timeout issue.  If it does
die, then it would seem more fundamental.

Can you start a long ssh transfer in one direction and see if the time
it takes to to die is consistent?

	cat /dev/zero | ssh host "cat > /dev/null"
