There is a difference in cables that can carry Gigabit Ethernet
(10/100/1000Mbps) as opposed to just Fast Ethernet (10/100Mbps) in
that IIRC Gigabit Ethernet requires an extra twisted pair. Thus you
find that if you use a Fast Ethernet cable to connect two Gigabit
ports, the connection will only be Fast Ethernet.

You sure about that?. I thought its down to the number of pairs used in
the cable, normally Green and Orange but plus the Brown and Blue in Gig
working....


As far as any other hype is concerned, ethernet connections either
work or they don't,

Not quite that simple, length plays a large part in thruput...


though it should be remembered that if a faulty
connection causes a high error rate, then a proportion of the data
sent across it will be corrupted and will have to be resent, and
therefore the net data rate across the connection will be reduced.

A vaguely interesting point is made in the test report however,
referring to cheap ethernet cable not meeting LAN spec. Quite what that
means in practice, I'm not sure.
