11. Troubleshooting
If you encounter any problems during the installation, or to confirm that the driver is installed
properly, please read the following troubleshooting section.
In Windows 98:
To check that the Wireless LAN PC Card is installed properly, please do the following:
1
From the “Start” menu, click “Settings”, then click “Control Panel”, and then
double click “Network”. Choose the “Configuration” tab.
If you find the “Wireless LAN PC Card”, it means the card is detected properly. If you see the
yellow question-mark “?” means the resources are conflicting.
2
Right click on “My Computer” and select “Properties”. Select the “Device Manager” and click on the “Network adapters”.
You will find the “Wireless LAN PC Card” if it is installed successfully. If you see the yellow
sign, the resources are conflicting. Please check the following. (For details, refer to the documentation that comes with your computer.)
(1) Check to see if your computer supports 3.3V card.
(2) Check to see if your computer has a free IRQ. If not, make an IRQ free by assigning the
same IRQ to some devices. For example COM1, COM2 can be assigned the same IRQ
values.
(3) Check that you have inserted the right card and have installed the proper driver.
In Windows 2000:
1
Click the Windows 2000 Diagnostics.
See if there is any conflict in the resource allocation or the I/O address, IRQ allocations. If you
find that the IRQ or I/O addresses are already assigned to some other devices, you must
change that value. I/O address needs 40h byte length.
2
Go to the “Control Panel” then double click “PC Card”.
You will see “Wireless LAN PC Card”. Double clicking on that will show you the card information, driver name and the driver file. You must confirm the name of the driver and the driver file

A type of wireless transmission.
Mode used for exchanging data between devices that have wireless LAN PC cards installed,
without going via an access point.
Channel
Wireless LAN devices that comply with IEEE802.11b transmit using a specified wireless channel
from wireless channels 1 to 14. (This device has 11 channels (1 to 11) that can be used. The
channels that can be used vary with the country or region.)
It may be possible to use the same channel on a different network, however, the transmission
speed may be reduced.
It is recommended to use a different channel.
DHCP (Dynamic Host Configuration Protocol)
When building a TCP/IP network, it is necessary to assign IP addresses to devices on the network.
This protocol assigns IP address automatically.
DHCP client function
This function allows for automatically receiving IP addresses from DHCP servers connected to the
same network.
This function is found in most computers. If the computer is connected to the DHCP server on the
network, it is also possible to automatically get an IP address for the computer.
DHCP server
This server allows automatically assigning IP addresses, subnet masks, and gateway addresses to
devices connected on the network. By using this function, a computer connected to the DHCP
server via a wireless connection can also automatically receive an IP address.
Gateway
