If your hub is sufficiently intelligent, some devices can use
full duplex while others use half duplex. Hubs smart enough
to do this usually also allow some nodes to use 10BaseT while
others use 100BaseT, and they typically have indicator lights
for speed and duplex as well as link and traffic. (Some of
these may be indicated by colour or blinking, of course.)
Hubs that do this often also perform switching (sending
packets only to the nodes for which they are designated).
Basically, we're talking about quality network hardware.
If your hub is just a dumb broadcast repeater with several
ports, then everything connected to it has to speak the
same protocol, naturally.
As far as the original poster's question, I really don't
know what would prevent a LAN segment from using full
duplex if all the hardware supports it. DOES all the
hardware support it? And do all the NICs support the
automagic negotiation? Are your cables all category 5?
Lots of collisions? How many is a lot? How big is
the network, and how much traffic does it see?
You said you can't get 100BaseT full duplex. Can you
get 100BaseT at all?
