@Alexandre. I will do, thanks again

Alexandre Thank you very much Tried again with that sequence, ie Ethernet, then power then reboot It worked! (on second attempt) brilliant, thanks, perhaps I was being too impatient with it before.

Coming at this with no networking experience Have set up my Deco wifi network and really happy with it Now trying to add my NAS, it's an older model WD MyWorldBook which I've completely reset to...
