HI ALL

I HAVE JUST PURCHASED X 2 RE200 AC750 RANGE EXTENDERS. I HAVE SET THEM BOTH UP IDENTICALLY AND THEY LINK TO MY BROADBAND AND THE TETHER APP RECOGNISES THEM. I LIVE IN A BUNGALOW AND ONE JUST WASNT ENOUGH TO BOOST THROUGH THE WALLS INTO THE BEDROOM. I SET THEM BOTH UP EXACTLY THE SAME AND STILL THE SINGLE ONE IN THE BEDROOM HAS A RED LIGHT SO THE RANGE FROM THE ROUTER IS TO FAR. I THOUGHT THEY WERE SUPPOSED TO BOUNCE OFF EACH OTHER TO ENABLE THE RANEG TO GO FURTHER SO HENCE I WAS EXPECTING MY BEDROOM ONE TO WORK PERFECT. I HAVE BUFFERING WHILST TRYING TO WATCH MY FIRESTICK OR CHROMECAST SO WAS DISAPPOINTED. NOT SURE IF I HAVE SET THEM UP CORRECT THE 2ND RANGE EXTENDER IN THE BEDROOM STAYS ON RED SO IT IS TO FAR FROM THE ROUTER. THE OTHER ONE IN MY HALLWAY WORKS PERFECT. ANY SUGGESTIONS AND HELP WOULD BE MUCH APPRECIATED.
