Thanks Russ and Gianni, I am at work now so can't follow your advice until I get home this evening. The reason I have not run Ethernet direct from the ID41 to the router is that I need a huge length of cable that I don't have (but will try to invest in). Also, from memory (but might be wrong), I think that the Sky Q router only has one Ethernet socket and this is currently being used by a Vodafone suresignal device.
Cheers
Bernie
