Are the coax cables for tv/broadband interchangeable? I have some old telewest coax points in the house so was looking at going the self install route. Problem is that the broadband coax is in a cupboard in the middle of nowhere so I'd like to plug the router into the coax that comes in behind the TV (broadband only, not having tv). If this is possible I can self install next week otherwise I'm going to have to wait for an engineer visit.
Yes. Power levels may vary though.
