Right now I am using a Wi-Fi connection from my router to the Hopper downstairs. But I am thinking of using a MoCA setup instead. Would that be much faster? Upstairs, there is a coax cable sitting next to the router and the other end of the coax sitting next to the Joey. They aren't physically connected yet. What interfaces do I need buy to connect them to the router and Joey and which connections? Thanks for any help.
