When my system was installed the installer said the hopper needed to be as close as possible to my router which is in the basement so I let him it there and the Joeys in the Living Room and Bed Room. The I discovered when trying to use PIP and some other features, they are only available on the Hopper. I decided to move the Hopper upstairs so I ran a network cable to the Living room so there would be no issue with wireless fade and traded the Hopper and Joey's positions. The Hopper would not get a signal from the satellite using the cable that the Joey was connected into so I put them back where they were. Is there some reason this would happen?
