I do now - thanks ;-]

Can't easily tell. Suffice to say the main 16 port hub was given to me at
least 5
years ago and I doubt it's 100Mbps.

Indeed. I've just tried a copy from client to linkstation and am getting
4MBps - not 900KBps and the reason is doubtless that they're going through
only the router - no other switches / hubs anywhere. I see Novatech are
doing an Edimax 16 port switch for £25 so I'll probably go for that.

Hubs work at one speed, switches work at the most appropriate speed - that's
the
difference isn't it?
