HARDWARE INSTALLATION
LED Indicator
Power (PWR)
The PWR indicator lights green while the Wireless CardBus Card is connecting to
the CardBus or PCMCIA slot, otherwise, it is off.
ACT (Activity)
The ACT indicator blinks green when the Wireless CardBus Card is connected to a
network successfully and transmitting data. Otherwise the indicator is off whiles the
Wireless LAN is stand by.
Check the installation
The LEDs of the Wireless CardBus Card are clearly visible and the status of the
network link can be seen instantly:
1. Once the device is plugged to the station’s CardBus slot, the PWR LED of the
Wireless CardBus Card will light up indicating a normal status.
2. When the device plugged to the station’s CardBus slot and the driver was
installed, the ACT and PWR LED will start alternate blinking, it means that the
device is starting to scan the wireless devices near the Wireless CardBus Card.
3. While the Wireless CardBus Card linked up and transmitting data to the Access
Point or to other Wireless LAN station, the ACT LED will start blinking.

4
SOFTWARE INSTALLATION
This section will lead you to install the driver and utility of the Wireless CardBus
Card.
Windows 2000/XP Utility and Driver Installation
1. Insert the Wireless CardBus Card Driver & Utility CD-ROM into computer’s
CD-ROM Drive and it will automatically run a setup menu and install the driver
and the utility.
2. Click Install Utility button to install the wireless adapter driver and utility.
3. The Install Shield Wizard screen will appear. Click “Next” to continue.
4. The installation program will help you to setup the Wireless CardBus utility.
Be noted that the Windows XP have its own Wireless Utility; you can either
use the utility of Windows XP or the provided utility.
5. When the Wireless CardBus Card was installed, you will see the icon on the
Windows task bar.
When the icon in the toolbar represents in full green color then the signal
strength has an excellent performance with the AP, if it represents in yellow
color then the signal strength has a fair performance with the AP, and if the icon
represents no color, then the signal strength has a worst performance with the
wireless station.

Wireless Utility Setting
I. Link Information
The default page is as below after launching the Utility program.
Status: Shows the BSSID associated, which can be used to identify the wireless
network.
SSID: Shows current SSID, which must be the same for the wireless client and AP
in order for communication to be established.
Frequency: Shows the current frequency used for wireless network.
Wireless Mode: Shows the current wireless mode used for wireless communication.
Encryption: Shows the current encryption mode used for wireless network.
TxRate: Shows the current data rate used for transmitting.
Channel: Shows the current channel for communication.
Link Quality: Shows the link quality of the 108Mbps wireless LAN PC card with
the Access Point when operating under Infrastructure mode.
Signal Strength: Shows the wireless signal strength of the connection between the
108Mbps wireless LAN PC card with the Access Point.
Data Rate: Shows the statistics of data transfer, and the calculation is based on the
number of packets transmitted and received.

6
II. Configuration
This is the page where changes the basic settings of the PC card with the minimum
amount of effort to implement a secure wireless network environment.
SSID: Service Set Identifier, which is a unique name shared among all clients and
nodes in a wireless network. The SSID must be identical for each clients and nodes
in the wireless network.
Wireless Mode: There are two types available for selection
●Infrastructure – to establish wireless communication with LAN and other wireless
clients through the use the Access Points.
●Ad-Hoc – to establish point-to-point wireless communication directly with other
wireless client devices such as wireless network PCI Card.
AdHoc Band: There are two bands available for selection- 11B and 11G
Channel: The value of channel that AP will operate in. User can select the channel
range of 1 to 11 for North America (FCC) domain and 1 to 13 for European (ETSI)
domain.
Tx Rate: Select the data rate for data transmission.
Power Mode: There are 3 modes to choose.
●Continuous Access Mode (default) – the PC card is constantly operating with full
power and it consumes the most power.
●Maximum Power Save – the PC card consumes the least power and only operates
when there is wireless network activity.
●Power Save – the PC card consumes the moderate level of power.
7
Preamble: Select Long or Short Preamble type. Preamble is a sequence of bits
transmitted at 1Mbps that allows the PHY circuitry to reach steady-state
demodulation and synchronization of bit clock and frame start. Two different
preambles and headers are defined: the mandatory supported Long Preamble and
header, which interoperate with the 1 Mbit/s and 2 Mbit/s DSSS specification (as
described in IEEE Std 802.11), and an optional Short Preamble and header (as
described in IEEE Std 802.11b). At the receiver, the Preamble and header are
processed to aid in demodulation and delivery of the PSDU. The Short Preamble
and header may be used to minimize overhead and, thus, maximize the network
data throughput. However, the Short Preamble is supported only from the IEEE
802.11b (High- Rate) standard and not from the original IEEE 802.11. That means
that stations using Short-Preamble cannot communicate with stations implementing
the original version of the protocol. Click “Apply” for the changes to take effect.
Support Band: There are three functions for users select, including 11B, 11G and
eXtended Range. The default setting is 11B, 11G and eXtended Range enable,
which is interoperable with both 11B and 11G devices, and provide more than
500m connection ability.
Note: user must select one of 11B or 11G at least, otherwise the wireless
connection will not function.
III. Advanced
This is the page to configure Security settings of 108Mbps wireless LAN PC card.
Encryption: 4 options are available: Disable, Enable, WPA/WPA2 and WPA-
PSK/WPA2-PSK. Select Shared Key or Auto for WEP data encryption feature.

8
Shared Key – the sender and receiver shares the common key for data
communication, and the key is used for extended length of time.
Auto – depend on the communication to establish, and automatically use the proper
authentication mode.
The following will only be activated to allow for configuration when Encryption is
enabled.
Network Key: choose the encryption way, either in HEX or ASCII formats, and
enter the password in the blank space.
Key Length: select 64 or 128 bits as the length of the keys
Default Key: select one of the 4 keys to use.
Key Format: ASCII or HEX
If WPA/WPA2 is selected, configuration is enabled. Please click the
“configuration”. The below window is pop up. Then, please select the certificate
that user wants to use and enter the server name and login name
If WPA-PSK/WPA2-PSK is selected, click the configuration button. The popping
window is as the below. Please enter the key.

IV. Site Survey
This page allows user to enable the Site Survey function to scan for the available
wireless network (wireless clients and Access Points) and establish wireless
communications with one.
Available Network – displays the wireless networks (wireless clients and Access
Points) that are in signal range.
Select any one of them to establish communications by simply mouse double-click
or click on the “Connect” button.
Click “Refresh” button to start scanning for available network again.
