CONNECTING YOUR WLAN USB ADAPTER TO PC
Quick Start Guide
 Connect your WLAN USB dongle to
your PC.
 Install driver.

Wireless LAN network defined by IEEE 802.11b/g standard committee
could be configured as :
 Ad Hoc wireless LAN, or
 Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards, this
group of PCs is called a BSS (Basic Service Set). PCs in this group can use
their wireless LAN cards to communicate with each other, but can not
connect to the Internet.
Ad Hoc WirelessNetwork Infrastructure Wireless Network
The most obvious difference between Infrastructure wireless network
and Ad Hoc wireless network is that the PCs in Infrastructure wireless
network can access the resource in the Internet through Access Point.
Depending on your requirement, you can easily set up your PC’s
network to be a “Ad Hoc” or “Infrastructure” wireless network. Generally
speaking, if in your network, there is an Access Point in it, we recommend
you to set your network as an “Infrastructure”, so it can connect to
the Internet.

To use the WLAN Mini USB Adapter with a computing device, the WLAN
Mini USB Adapter must be equipped with an USB 1.1 or 2.0 Interface. All
drivers and supporting software for the WLAN Mini USB Adapter must be
installed and configured first.
Ask your system administrator for the following information, which you
may need to provide during driver installation :
 Your Wireless Client Name.
 Your Wireless SSID.
 Your computer’s unique client name and workgroup name.
 For your network account, your user name and password.
 Your IP address, gateway address, and subnet mask if you’re not
using a DHCP server.
Any computer on a network is identified by a unique network address.
There are two methods to assign a network address to a computer on a
TCP/IP network :
 Static IP addressing.
 Dynamic IP addressing (DHCP).
In network with static IP addressing, the network administrator manually
assigns an IP address to each computer. Once a static IP address is
assigned, a computer uses the same IP address every time it reboots and
logs on to the network. You may manually change the IP address in the
Network Properties dialog box. Network using static IP address is easy to
set up and do not require additional network management software.
In network with dynamic IP addressing, a DHCP server in the network
dynamically assigns IP addresses to all clients every time they log on to
the network. Network using dynamic IP address requires setting up and
running a DHCP Server.

installation program after you insert the disk into your CD drive.
Step 1 :
Insert the installation & driver
DC into your CD-ROM.
Step 2 :
Click Next to continue.
Step 3 :
Click Next to install at the
designated
folder. Or, click “Browse”
to select different folder.

Step 4 :
Start copying files until it
finishes the installation.
Step 5 :
Click Finish to complete
installation.
Step 6 :
After finished install driver and utility on your system, plug the USB
adapter into the USB port of your PC. Windows XP/2000 will automatically
detect the USB Adapter.

WLAN USB Adapter uses its own management software. All functions
controlled by users are provided by this application. When you insert the
WLAN USB Adapter into the USB port of your PC, a new icon should
appear in the Windows System Tray automatically.
If the icon is in red, it means that WLAN USB Adapter configuration is
invalid or incomplete. Double click on that icon and the configuration
window will pop up as shown below. It shows the SSID of available
network. Once a network is chosen, the signal strength and link quality
are displayed.
The Link Quality and Signal Strength bar chart is only active when the
node is in Infrastructure Mode. The bar graph displays the quality and
strength of the link between the node and its Access Point. Link Quality
is a measurement of receiving and transmitting performances over the
radio.
Tx/Rx Frame displays the instantaneous wireless Transmit and Receive
throughput in bytes per second. These values are updated every two
seconds.
The Configuration Tool contains
several fields where operating
parameters of the driver can be
viewed or changed. Changes to
any of the parameters in this
panel can be applied to the driver
without a need to restart the
computer.
Current Network Information
displays the current network

configuration. If you want to
change network configuration, click “More Setting”.

5.1 GENERAL CONNECTION SETTING
In this panel, you can modify the
general network connection setting,
enable/disable the WEP, load/
modify profile and other setting.
Through this control panel, you will
be able to access the corporate
wireless LAN or hot spots such as
hotel, airport, and conference hall.
Click “Change” to start input of
settings. The settings include :
 SSID.
 Network Type.
 Transmit Rate.
 Encryption.
 Authentication Mode.
When settings are input, click
“Apply” to confirm changes of
them.

5.2 WEP ENCRYPTION KEY SETTING
You may want an additional measure
of security on your wireless
network, which can be achieved by
using WEP (Wired Equivalent
Privacy) encryption. WEP encrypts
each frame transmitted from the
radio using one of the Keys entered
in this panel.
When an encrypted frame is received
it will only be accepted if it
decrypts correctly. This will only
happen if the receiver has the same
WEP Key used by the transmitter.
The default state in Encryption Setting is WEP disabled. Check “Enable
WEP” to enable the encryption.
For more WEP key setting, Click
“WEP Encryption Key Setting”.
Three authentication modes are
available: Open System, Shared Key
and Auto. The Open System uses
default key to authenticate the
station and Access Point. Once both
parties are authenticated, the
station is allowed to send and receive
data from the network.
However, the data are not encrypted.
In Shared Key system, the station and Access Point are authenticated
each other. The data frame is also encrypted by the WEP key.
In Auto Mode, the Access Point takes control of network security setting
and station will follow the setting required from AP.

Click the “close box” at the upper right hand corner to return to Configuration
Tool. 9
5.3 WPA ENCRYPTION SETTING
WPA (Wi-Fi Protected Access) is a
security technology for wireless
networks. WPA improves on the
authentication and encryption features
of WEP (Wired Equivalent
Privacy).
To improve data encryption, WPA
utilizes its Temporal Key Integrity
Protocol (TKIP). TKIP provides
important
data encryption enhancements
including a per-packet key
mixing function, a message integrity
check (MIC, named Michael), an
extended initialization vector (IV)
with sequencing rules, and a rekeying
mechanism.
WPA Pre-Shared Key (WPA-PSK) is a
simplified but still powerful form of
WPA most suitable for home Wi-Fi
networking. To use WPA-PSK, a
person sets a static key or
“passphrase” as with WEP. But,
using TKIP, WPA-PSK automatically
changes the keys at a preset time
interval, making it much more
difficult for hackers to find and
exploit them.
The pre-shared key is consisting of
alpha-numeric characters including
punctuation and spaces between 8
and 63 characters long.Wireless
clients are only required to enter
the pre-shared key.If the pre-shared keys match, secure wireless

communications can begin to take place.
For more WPA setting, Click “WPA Encryption Setting”

5.4 PROFILE
Each profile represents specific settings of the USB adapter. You can set
the settings for each profile. Next time when you want to change the
USB adapter settings, you can just select the profile you want to use.

5.5 ADVANCED SETTING
Click “Advanced Setting” to select power consumption setting that has 3
different modes. In this panel, you can select different user interface
and country roaming.
It also allows you to set the threshold of fragmentation and RTS/CTS.
