Tips and Troubleshooting
 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 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 AirPort Extreme and the cables.
 Try to place your AirPort Extreme at least 25 feet 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.
 Certain electrical devices such as power lines, electrical railroad tracks, and power
stations
 Cordless telephones that operate in the 2.4 or 5 GHz range. If you have problems
with your phone or AirPort communication, change the channel your base station or
AirPort Extreme uses, or change the channel your phone uses.
 Nearby base stations using adjacent channels. For example, if base station A is set to
channel 1, base station B should be set to channel 6 or 11.
