some cables that work flawlessly at 10mbit aren't 100mbit capable...
according to the big man on campus (william green), cables longer than
about 30 feet aren't reliable at over 10mbit if they terminate in
rj45 endings instead of punchdown style wallboxen. i've experienced this
on my homenet---a windows machine with a 100mbit adapater negotiates at
100mbit (because again according to william, the negotiation pulse would
run over barbed wire (!)), but fails to actually function well at that speed.
sometimes it won't even ping, but more usually it can limp along, getting
maybe 1 packet in 4 on a continuous ping thru. which means dhcp takes about
a minute or two to finish happening, and everything netrelated sucks.
do you get even a single packet thru? have you tried the same computer
with shorter cables? are the machines that work closer to the hub than
those that don't? i think with the information you've provided you can
rule out the hub being bad. what happens if you force the other machines to
10mb?
