The hub is a `Micro100' manufactured by NetWorth of Irving, TX.

Here is some output from netstat, after a ping -f (which dropped 14%
of the packets) and an ftp transfer (which didn't finish).

The cable really is CAT5, although our local wiring expert seems
to think it is not of sufficiently high grade for 100BaseTX.
New cable is on the way.

The card+driver work fine (and very fast!) through our 10BaseT
hub, using the same cables.

Thanks for the response,
Dave
