Unless you have specific reasons for buying a hub, buy a 10/100/1000 switch instead along with some CAT6 cable, or CAT5e if you plan on running them a ways.
Oh, I completely spaced the fact that he said "Hub." Yeah Joe -- you want a switch. Hubs SUUUCK. Stfu, pull up your coinpurse and spend a little money. =P
Sadly, I only have a 10/100 switch for my network. The Cable is CAT-5 (I got a box of 1,000ft for free!), but I ran two runs @ 300+ feet, so it's ok. I'll live without running gig for a while.
