I've just found a Cat5e cable with 8 wires (4 pairs) connected, so it looks like Cat5 is 4 wires & Cat5e/6 are 8 wires.
Just to let you know - I plugged in a 5m cat 6 cable and it comes up as 1gb/s whatever I plug the other end into. Cat 5/5e cables do. seem to give 1gb/s provided they are short 1m jobs.
What version of HomeHub do you have?
It may just be showing that it is plugged into the Gigabit capable port (the one labelled GigE) rather than showing that a Gigabit connection has actually been established with a Gigabit capable device.
Cat5/5e supports distances up to 100m. For any decent quality cable following the standards whether 5m or 1m should be of no significance.
Note that the help page seems a bit misleading when talking about Gigabit allowing you to make use of Infinity speeds. That should only apply to those on Infinity 3 or 4 which give broadband connection speeds greater than 100Mbps.

BT home hub 5. All I know is that if I use the supplied 10m cable, the 'home network' shows 100mb/s on that port and if I use a cat6 5m cable (or indeed a 1m cat5/5e patch cable) it shows as 1gb/s. What it is plugged into seems to be immaterial. It might make no difference to actual performance of course...
Yv port just labelled 'Ethernet' but I was wrong earlier about the receiving connection. This is the run down.
BT cable into apple time capsule or yv - 100mb/s
Cat 6 or any other cable I've tried into Apple TC- 1gb/s
Cat6 into yv - 100mb/s
So there are two variables, but basically don't use the BT cable unless it is a direct connection and your broadband speed is not higher than 100mb/s. I use the TC to split the internet between three devices including the yv box, so I will carry on with the cat6.
