Great point. That's bitten me in the a** before. Make absolutely certain that you have a cable with all 4 pairs wired in. 100Mbit ethernet only used two pairs, Gigabit uses all four. If you connect a gigabit port with a two pair cable the best you can do is 100Mbit/s. Also, unless you are going some major distance Cat5e cable is sufficient. In fact cat 5 cable will do 1Gb/s over short distances. When I got burned by this it turned out that the cable I got with my 3Com <something-or-other> only terminated pairs 1 and 2. As I said before, that's sufficient for Fast-Ethernet but not for Gigabit-Ethernet. -- Chris
