I have a HR-20 HD DVR receiver.. It's connected via phone line only besides the coax coming in... I want to connect it to the wireless internet i recently installed to my PC... What device do i need for the Directv... I already have the net router working fine.. I went to best buy, but i wasn't sure about something the guy recommended as he showed me a plug in internet connection that i connect one to PC and one to DVR? Seems like it was another router and redundant solution... I'm thinking there is one stand along device i can plug in via the ethernet connection to the dvr that picks up the wifi or is there?
