I would like to know what to buy to extend the Bluetooth range from my amplifier downstairs to my iPad upstairs. The amplifier sends the music through the speakers in the ceilings of my house which I control from my iPad using Spotify. Right now, I have to leave my iPad halfway down the stairs or it loses connection.
Thanks.
