We moved our bedroom upstairs and the 722 DVR went with. Works fine. Moved the 311 downstairs into the room the 722 came out of. It now has no signal and a switch test says no switch box detected. The 211 in a third room is also working. The switch is a DPP 33 w/separator. All were working properly before we made the change. What is wrong? The whole system has always seemed a bit overdone, considering the "dish garden" in our yard, but they said we needed three dishes to get HD and local channels. I just want it to work. Any ideas?
