Difficult to put both ends in at present. (is that wise -never heard of this test before)

Run is under floorboards. Will have to source another cable

That's the point of changing the cable. If it is supposed to run at 1 Gig subject to supply data rate (i.e. LED is green) but doesn't then it might be faulty. It would quite likely run at 100 meg as you've proved.

It decides the rate based on Autonegotiation described at https://en.wikipedia.org/wiki/Autonegotiation
