AirPort Extreme Placement Considerations
The following recommendations can help your AirPort Extreme achieve maximum
wireless range and optimal network coverage.
 Place your AirPort Extreme in an open area where there are few obstructions, such as
large pieces of furniture or walls. Try to place it away from metallic surfaces.
 If you place your AirPort Extreme behind furniture, keep at least an inch of space
between the AirPort Extreme and the edge of the furniture.
 Avoid placing your AirPort Extreme in areas surrounded by metal surfaces on
three or more sides.
 If you place your AirPort Extreme in an entertainment center with your stereo
equipment, avoid completely surrounding the AirPort Extreme with audio, video, or
power cables. Place your AirPort Extreme so that the cables are to one side. Maintain
as much space as possible between the AirPort Extreme and the cables.
 Try to place your AirPort Extreme at least 25 feet (7.6 meters) from a microwave oven,
2.4 or 5 gigahertz (GHz) cordless phones, or other sources of interference.
Items That Can Cause Interference with AirPort
The farther away the interference source, the less likely it is to cause a problem. The
following items can cause interference with AirPort communication:
 Microwave ovens
 Direct Satellite Service (DSS) radio frequency leakage
 The original coaxial cable that came with certain types of satellite dishes. Contact the
device manufacturer and obtain newer cables.
