Wireless LAN Related

Q1 The Wireless LAN device is operating properly, but I cannot connect to the Internet
or to another computer.
This is due to an incorrect configuration, or a configuration error. Check the follow-
ing check lists:
A1 If you are using a computer-to-computer (Ad Hoc) network connection, check that the name
of the configured network (SSID) is correct. The network name (SSID) is case sensitive.
A2 If you are using a network key (encryption key), you have to use the same network keys for
an AP (Access Point) or a computer-to-computer network (Ad Hoc). The network key of the
AP is configured in the AP management program. Ask your network administrator or AP man-
ager 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 > Perfor-
mance 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 Media.
A4 Referring to A2 of Q3, Check that the network bridge configuration is correct.
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.
Even if the network provides DHCP, the server may not allocate an IP address to the client
properly, and the client station cannot connect to the network.
A2 Referring to A2 of Q1, check that the network key is correct.
A3 Referring to Q4, check that AP is operating properly.
Q3 I cannot connect to the AP.
Check the Computer Settings
A1 Verify whether the wireless LAN function of the computer is on by doing the following. If the
wireless LAN function is off, turn it on.
- For Windows XP, verify that the wireless network connection has been set to "Enable" in Start
> Control Panel > Network Connections.
- Check if the wireless LAN is turned on.
A2 Verify whether the same network key (encryption key) has been entered in both the AP and
the computer.
The network key is an encryption key for encrypting data transmitted between the AP and the
computer. It is recommended setting the network key manually.
