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 your base
station or AirPort Express uses.
• Adjacent base stations using nearby channels. For example, if base station A is set to
channel 1, base station B should be set to channel 4 or higher.
