I currently have a HR20-100 in my living room and an HR20-100 in my bedroom. I would love to get DirecTV's Whole-Home DVR setup, but not sure if I have all the right setup pieces. Neither of the DVR's is anywhere near an Ethernet connection as everything I use for the internet is via wi-fi: a cable modem connected to an Apple Time Capsule in an entirely different room in the house.
Does Whole-Home DVR need Ethernet to work? Also, is now the time to also get the most recent model of DirecTV's DVR's?
