Was on vacation 2 weeks ago. Was able to connect to one of my Hoppers via DA but not the one connected direectly to my router. Now I can't get video from either. When I load DA, I can see a list of "My Recordings" but if I try to watch anything, live or recorded I get a message that the receiver appears to be off line. I've checked the network connections and the show up as OK. Any ideas.
