I have an SD DVR in a room that is too far away from the room where my Wireless router is to run a cable to. I want to get my DVR to connect to the internet (mainly so I can program the DVR when I'm away from home). How do I get the DVR connected to the router without cables? Everything I read says something about connecting a cable to the router and to the DVR, but that doesn't sound like wireless to me. Am I missing something?
