I'm suggesting the router CPU being bogged in relation to only your
network performance issues.  I agree that would have no bearing on the
peculiar behavior of tracerte, unless it was discarding the ICMP
packets.

Also I cling to that because of an experience I had with one of my
linksys routers having poor performance in one location but then work
perfectly fine doing the same thing in a completely different
household, not so much because of your problem with the poor
performance.

the high latency is not an issue as well?

It would be interesting to get a Wireshark capture of the traffic to
see what the difference is between the Windoze and OS/2 trace route
versions.
