Chapter 3 Tips and Troubleshooting16
Avoiding Interference
The farther away the interference source, the less likely it is to cause a problem. The following
can interfere with AirPort communication:
ÂMicrowave ovens
ÂDirect Satellite Service (DSS) radio frequency leakage
ÂThe original coaxial cable that might have come with a satellite dish. Contact the device
manufacturer and get newer cables.
ÂCertain electrical devices such as power lines, railroad tracks, and power stations
ÂCordless 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 Extreme uses, or
change the channel your phone uses.
ÂNearby 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
ÂTry 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).
ÂMake sure you’re connecting to the correct wireless network.
