Well most if not all of the hubs I have ever set up/used have been full duplex IF the connecting host is set up that way.

not answering your question but its almost pointless running a hub these days. multiport switches that massively out perform hubs are "cheap as chips".

take your hub.. and put it in the bin closet. Buy a switch.

It would depend on the chipset used to do the media interface but as a generaly rule that vast majority of all hubs were full duplex. As has been pointed out. It depends on the cards driving the hubs from the client side and if they are forced half duplex or not.

Now do as you have been told and throw the hub in the trash and get your self a switch off of Ebay or the likes and lets never have this talk of hubs again. OK?

Please set you hub on fire. Do it for me.

Hubs are a share media, that is, when someone is sending on the wire, on any port, the others can not send. If they do you have a collision. Collisions are bad M'kay. This causes resends. Which makes things like NFS which uses UDP packets suck brick.

Switch are effectively point to point connections, the media is not shared, 2 PC's can send data at the same time, to different ports.

most if not all switches use full duplex, because the connections to the switch are all point to point and there is no need to worry about collisions that another PC might sending on the same wire we can use this.

The switch is a really large traffic agent and makes sure that packets do not collide and only one party is always sending on the same wire. They other use Store and Forward (e.g. buffer the packet(s) and send them out the destination port). Another method which is used less is Cut-Through which just reads the destination and passes the data on, which can/could cause malformed packets under load.

Don't use a hub, save yourself the grief and buy a 8 port 100Mbps switch for 25$
