I am using MRV thoughout most of the house and in one location I need another ethernet jack for a Roku. I am already splitting the one ethernet jack in the room through a cool gizmo that splits the pairs of the Cat5 wire, but now I have 4 networked devices in one room and am trying to avoid adding a small switch\hub

I thought I read somewhere that there was a way to get another network connection somehow through the Directv MRV setup--I have an HR21 in the room I want to add the connection too. Is there a way??
