I just got an upgrade to the Whole Home DVR setup with MRV. Here's my set up: Bedroom: HR20-700 Living Room: HR23-700 Basement: HR24-200, XBOX 360, Playstation 3, Blu Ray, Wii My cable modem is not close to any of the receivers and I currently have a Belkin N+ wireless router connected to it. Both the HR20 and HR23 have the little white DECA boxes connected with an ethernet going from the DECA box to the ethernet port on the back of each respective receiver. The HR 24 has a black (I assume DECA) box with an ethernet cord coming from the box, but not connected to the receiver. What exactly do I need in each location to connect each receiver to the internet, as well as connecting my XBOX, PS3, Blu Ray, and Wii for gaming?
