Q1 The Wireless LAN device is operating properly, but I cannot connect to the
network.
This is due to an incorrect configuration, or a configuration error. Check the
following check lists:
A1
If you are using a computer-to-computer network (peer-to-peer) connection,
check that the name of the configured network is correct. The network name used
to connect should be the same in all computers. The network name is case
sensitive, if the name contains letters.
A2
If you are using a network key (encryption key), an AP (Access Point) and a
computer-to-computer network (peer-to-peer), you have to use the same network
key. The network key of the AP is configured in the AP management program.
Ask your network administrator for more detailed information.
A3
Check that the device driver is properly installed. If the driver is not properly
installed, you will find a yellow exclamation mark on the network icon by
clicking Start > Control Panel > Performance and Maintenance > System >
Hardware tab > Device Manager > Network adapters > Wireless LAN adapter. If
there is a yellow exclamation mark, please reinstall the device driver with the
system software CD.
A4
To connect to an access point using network authentication (Shared key):
- In Windows XP, select Network Authentication (Shared mode) in the Wireless
Network Properties window.
- If you use the wireless LAN program (PROSet) in Windows 2000, make sure
that the network authentication mode is configure to Shared in security settings.
For more information on the network authentication configuration procedures,
ask your access point administrator.
Q2 The signal strength is excellent, but I cannot connect to the network.
Even if the signal strength is excellent, the network connection may not operate
properly if the TCP/IP properties are not properly configured, or the network key
(encryption key) is incorrect.
A1
Check that the TCP/IP properties are configured properly. When you connect to
an AP, click the Wireless Network Connection icon on the taskbar and select the
Support tab. If the IP is not allocated properly, the IP address will be displayed
as follows. (e.g. 169.254.xxx.xxx)
If the network does not provide DHCP, you have to specify the correct IP address
by asking your network administrator.
