OK, this is solved now so thought I would post back to the list in
case future users search the archives for the same problem and for
anyone who is interested ;)

Thanks Tony, you answer was partially it. I hadn't correctly enabled
WOL on the NIC card:

Also the other problem was I was using a dual Gigabit NIC, in
particular I was using the 2nd port, but it turns out WOL only works
on the first port! Just in case anyone finds them self's in a similar

Many thanks,
James ;)
