I just had dish installed and the only problem i've run across so far is that the remote in one room is controlling the the other 811 receiver which is located in a completely different room. They are nowhere near each other and the rooms are not close to each other. Any way to set these things up to use different frequencies so one remote doesn't control the other receiver and vice versa? I already tried removing the small antenna hookup on the back but then the receiver doesn't respond to remote commands at all.
