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
 DSS (Direct Satellite Service) 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 gigahertz (GHz) range. If you have
problems with your phone or AirPort communication, change the channel of
your base station.
 Other AirPort and wireless networks
 Adjacent base stations using nearby channels. If base station A is set to channel 1,
base station B should be set to channel 6 or 11. For best results, use channels 1, 6,
or 11 when operating your base station in the 2.4 GHz range.
 Moving objects that temporarily place metal between your computer and the
base station
