Interference is caused by electromagnetic fields or radio frequency interference. For wired cables, make sure wires are not routed next to motors or fluorescent lights that can cause interference.

Check to make sure that the cable is not kinked or worn. Cables should be routed through walls or ceilings, not strung across the floor.
