• Verify that you have the correct network settings.
Incorrect network settings will inhibit networked computers
from communicating properly. For example, a computer may try
to detect a network by using the wrong name or by using a
different communication protocol than all of the other
computers on the network. You can view and modify network
settings in the Broadband Network Utility.
My wireless network connection works occasionally.
• Verify that your computer is within the recommended range of
the base station and that there is no interference from other
wireless devices.
Signals that are transmitted between the base station and a
wireless adapter or PC Card are affected by interference from
other wireless devices—including 2.4 GHz cordless phones,
microwave ovens, and neighboring wireless networks. Move the
other devices as needed, and refrain from using them while you
are using the network. Alternatively, you can move the network.
To minimize interference from another wireless network, try
changing channels. For more information about changing your
network channel, see Chapter 6.
• Verify that other devices on your network that may be running
NAT and/or DHCP servers have NAT and DHCP servers
disabled.
Devices such as your modem may have NAT and/or Dynamic
Host Configuration Protocol (DHCP) servers running at the same
time as the base station. If this is the case, the devices will
interfere with each other and cause intermittent failures. For
instructions for disabling NAT and DHCP servers on the other
device, see the documentation for the other device.
My computer is within the recommended range of the base
station; however, it can’t detect the network.
• Verify that physical barriers and other forms of interference are
limited.
Physical barriers between the computer and the base station,
and interference from microwave ovens and other wireless
devices—including 2.4 GHz cordless phones and neighboring
wireless networks—affect the signals that are transmitted
between the base station and a wireless adapter or PC Card. If
this occurs, move your network components closer to the base
station.
