 Don’t place books, papers, or other objects on top of the AirPort Time Capsule. These may
interfere with AirPort Time Capsule cooling.
 Place your AirPort Time Capsule at least 25 feet (8 meters) from any microwave oven,
2.4 GHz cordless phone, or other source of interference.
Avoiding Interference
The farther away the interference source, the less likely it is to cause a problem. The following
can interfere with AirPort communication:
 Microwave ovens
 Direct Satellite Service (DSS) radio frequency leakage
 The original coaxial cable that might have come with a satellite dish. Contact the device
manufacturer and get newer cables.
 Certain electrical devices such as power lines, railroad tracks, and power stations
 Cordless telephones that operate in the 2.4GHz or 5GHz range. If you have problems with
your phone or AirPort communication, change the channel your AirPort Time Capsule uses,
or change the channel your phone uses.
 Nearby base stations using adjacent channels. For example, if device A is set to channel 1,
base station B should be set to channel 6 or 11.
If You Can’t Connect to the Internet
 Try connecting to the Internet directly from your computer. If you can’t connect, check to
make sure your network settings are correct. If they appear to be correct and you still can’t
connect, contact your Internet service provider (ISP).
 Make sure you’re connecting to the correct wireless network.
