Hoping someone can help. Master BR has HD box not dvr...works fine...second HD box in living room non dvr...both tv's get nice reception. Hooked up internet in 3rd room (guestroom)....lose hd capabiity in Master....Move router to living room all is well. Moved an HD box to a tv in guest just to see what would happen. .Same thing...Master loses hd signal!
Not living there full time so difficult to call for service. Previous to HD...all outlets plus internet were received properly in all rooms. Call to Xfinity says it is due to signal loss having three hookups....ABSURD! Help from anyone is appreciated.
