Who knows why ISPs do anything? In fact my ISP (Zen Internet) is pretty
responsive and their support crew sound like human beings rather than
droids. That said, it's clear that the thin white cable supplied with
the router is simply not adequate for Gigabit Ethernet. Once I sussed
the problem, it was obvious that this was the case and I should have
realised it earlier. My old NAS is connected with a proper CAT-6 cable
and it was going full speed.

I'll be mailing Zen to let them know they should inform their customers
of this.
