Hardware Installation
Warnings: Network cards are sensitive to static electricity. To protect the card, always
touch the metal chassis of your notebook or the ground before handling the card.
1. Turn on your notebook.
2. Find an available Type II or Type III PCMCIA slot in your notebook.
3. With the PC Card’s 68-pin connector facing the PCMCIA slot, label side up, slide the
card completely into the slot as shown below.
Note: The PCMCIA slot allows you to “hot swap” PC Cards any time.
4. Install the appropriate driver into your system. Drivers can be found on the driver CD
that comes with the package. See the following section for instructions.

5
Driver and Utility Installation
The CD labeled “Driver and Utility CD” that comes with the package contains the software
drivers and utilities available for the WLAN Cardbus.
Note: You may find that the instructions here do not exactly match your version of
Windows. This is because these steps and screen shots were created from
Windows XP. Windows 98SE, Windows Millennium Edition, and Windows 2000
are similar, but not identical, to Windows XP.
1. Place the installation CD into the CD-ROM drive. The program will auto-run.
2. Windows XP will automatically install the driver.
3. Insert the adapter into your computer when you see the following message.

4. Once the utility has been installed into your system, the Found New Hardware
Wizard window will appears.
5. Select Yes, this time only and click Next.
6. Choose the Install the software automatically option, and click Next.

Utility Configuration
11
Power Save — Enable or disable the power saving feature.
Operating Mode — The adapter supports 802.11b, 802.11g and 802.11g turbo
mode. Check the type of network that you want to use for your wireless connection.
Note: 802.11g turbo mode is capable of Packet Bursting, Fast Frames, Compression,
and Dynamic Turbo. It delivers the maximum operation speed of up to 108 Mbps.
The WLAN Cardbus is backwards compatible with non-Turbo (legacy) devices.
Dynamic Turbo mode is only enabled when all devices on the wireless network are
SuperG with Dynamic Turbo enabled.
Security Tab
Go to the security tab to set the security features for your adapter.
Click on this security button to turn on/turn off the security
function.
Turn on the security function, and set detail parameters for your adapter.
To prevent unauthorized access, this adapter supports WEP (Wired Equivalent
Privacy), and WPA (Wi-Fi Protected Access).

EZ Connect™ g 108Mbps WLAN Cardbus
12
WEP
WEP (Wired Equivalent Privacy) implemented in the Wireless PC Card is based on
the RC4 encryption algorithm. The security keys provided to ensure data
confidentiality are four 10-bit keys for the 64-bit WEP setting and one 26-bit key for
the 128-bit WEP setting. WEP security protects your wireless LAN against
eavesdropping and unauthorized access by intruders.
Security Type — WEP (Wired Equivalent Privacy) is supported by the adapter to
prevent unauthorized access.
Key Type — Choose the Key Type (ASCII or Hex) from the drop-down list.
ASCII: 13 regular text characters. Hex: 26 digits (0~9, A~F) hexadecimal characters.
Authentication Mode — Choose Open or Shared.
Default Key — Choose the Key Number that has the encryption string you prefer. If
you are using a key generated from a passphrase, you must use the same
passphrase and key on each station.
Use Passphrase — Check this box to auto-generate security keys for WEP
encryption. Please note that you must use the same passphrase on all the stations in
your network.
WPA-PSK Encryption Type
WPA (Wi-Fi Protected Access) is a stronger wireless security solution than WEP. It
uses a combination of authentication and broadcast/session keys.
