Genie2 - New receivers out of range

I have a Genie2 and recently got two Genie wireless receivers to put on the other end of the house upstairs. One can plug in with a solid yellow light so I think that is okay but in the other room I get it blinking red so believe it is out of range. Rooms are right next to each other. I have considered moving my Genie2 to the other side of my downstairs TV (where it is now) in case the angle might help (case something is blocking it). If I move the Genie2 about 10 feet can I just move it or should I disconnect from power? If that does not help, does Directv provide anything that can be used to boost the signal to other parts of the house?
