Hi mixture! Thanks for that, and a happy new year to you, too!
The gigabit network out to the garage roof where the NAS lives is working great, thanks. Chuffed to bits, actually, and even my wife wonders how we managed without it (both an always-on NAS and a gigabit network!)

I've even got a pukka sheathed lightning conductor cable bonding the two buildings as well so hopefully no fried equipment at the other end in the event of a strike to either of them. Just a shame that running a cable down the street wasn't an option on holiday!
Thanks, mad jock, but I would be surprised. No snow on my wall, only the distant wall (low hanging roof to be exact) of the neighbour's distant house.
