I am new to directv and just got it installed yesterday. I have a Model HR-44-500 receiver. The installer connected the dish to my existing coax cable in the house. then another smaller genie in the bedroom attached to the coax. I have a friend at the office who has the same model receiver but has a wireless bridge wvbro-25. The wireless bridge then talks to genie mini in the bedrooms. His house is the about the same size as mine also. My friend says the TV's get the signal via his home wifi. He has been a long time directv subscriber and this wireless option is part of an upgrade he got say 2 years ago. I don't follow why they would use that wireless option wouldn't a wired be better for signal quality less chance of it being stepped on also. Unless the state of his existing wiring in the home is sub par. I am just trying to understand why his set up would be different then what I have.
