I can’t access the Internet from a computer on my wireless
network.
The following troubleshooting steps will help you track down and solve the
problem.
O
Make sure that the rest of your network is functioning correctly. Verify that
you can access the Internet from other computers on your network. If other
computers also cannot access the Internet, the problem might be with your
base station, modem, or Internet service provider (ISP).
Another common cause of Internet connection problems is disconnected
cabling. If the rest of your network is having problems, check the cable between
the base station and the broadband modem. Verify that you are using the
correct cable, that the cable is rmly attached, and that all status lights on
the network devices indicate that your connections are receiving power and
functioning properly.
O
Check for range or interference issues. You might be out of range of the
wireless base station or access point. Place the computer with the wireless
adapter in the same room as your base station and try connecting again.
Interference can also cause Internet connection problems. Signals that are
transmitted between the base station and a wireless adapter can be affected
by interference from other wireless devices—including 2.4 gigahertz (GHz)
cordless phones, microwave ovens, and neighboring wireless networks. Move
the other devices further from your wireless networking hardware as needed,
and refrain from using them while you are using the network. To minimize
interference from another wireless network, try changing channels. For more
information about conguring your wireless settings, see the documentation for
your wireless access point.
For more information about range issues, see Chapter 1, “Introduction.”
