Long story, I'm hoping someone can help me out here. I recently had whole home dvr service installed. I have an HR24 dvr and (3) HD receivers. I only have the dvr and (1) hd receiver hooked up. I am trying to get my internet connection established. I have the correct swm-2 splitter that feeds the (2) receivers. When I connect a known good ethernet cable into the back of the dvr and go through the network setup, it will not connect. I did a search and thought I needed a deca it inject the internet signal. After talking with the co. that did the install, they said that it was built into the receiver and as long as I had a swm head on the dish, it should hook right up. Is this correct of do I need the kit with whole home dvr service?
