Relocating the position of either the transmitter or amplifier/receiver may increase range and/or signal quality. In addition, changing your wireless router's broadcast channel (see router manual for instructions) can remove interference that you may experience. The maximum wireless range can be affected by walls, building material, and other wireless devices (such as cell phones) operating within the same area. This is true of almost every wireless device. For the highest quality sound, always try to maintain a line-of-sight wireless connection between the DTA-1T transmitter and DTA-1AR amplifier/receiver.
