1. Introduction
Thank you for purchasing your Wireless Local Area Net (WLAN) USB
Dnogle. You are about to install a networking system that is not only fast
and powerful, but also easy to set up and simple to maintain. In a short time
you and those in your network will be able to share a local printer and files,
access the Internet, and roam about the office wire-free.
Using radio frequency (RF) technology, WLANs transmit and receive
data over the air, minimizing the need for wired connections. Thus, WLANs
combine data connectivity with user mobility, and, through simplified
configuration, enable movable LANs.
This wireless networking solution has been designed for both large and
small businesses, and it is scalable so that you can easily add more users
and new network features as your business grows.
This manual will assist you in the installing WLAN USB Dongle.

2. Wireless LAN basics
Wireless LAN network defined by IEEE 802.11b standard committee could be
configured as:
• Ad Hoc wireless LAN or
• Infrastructure wireless LAN
Ad Hoc network is a group of notebooks with WLAN PC cards or USB dongles
called a BSS (Basic Service Set). These notebooks use their WLAN PC cards or USB
dongles to communicate with each other, and notebooks can not connect to the
Internet.
Figure 2-1 Ad Hoc wireless network
The most obvious differentiation between Infrastructure wireless network and
Ad Hoc wireless network is that the notebooks in Infrastructure wireless network can
make use of the resource in the Internet through Access Point.

Figure 2-2 Infrastructure wireless network
To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure”
wireless network depends completely on your requirement. Generally, if your network
environment has an Access Point, we recommend that you set it as “Infrastructure”
to connect to theInternet.

3. Windows Installation
The following section will assist you to install Wireless LAN USB successfully. You will
first install software (driver) and then connect the Wireless LAN USB, and finally set
the network properties to accommodate resource sharing and select the type of
wireless network that you wish to install. The Wireless LAN can easily be installed and
used, without bothering to connect cables for keeping your computer to use network
resources, as in case of wired LAN.
Before You Start
Here are some steps you will perform in establishing your wireless network
connection:
•Install the Access Point at first. AP is needed in case of infrastructure
network mode.
•Install the software using the Installation CD ROM
•Install the Wireless LAN USB Dongle
•Install the network protocol(s) required to communicate on your network.
Most likely you will need the TCP/IP protocol.

3.1 Installation and Configuration Procedures
Under Windows 98 SE
Please follow the following steps one by one in order to install the WLAN USB
Dongle successfully.
Step 1. Power on your computer and allow Windows 98 SE to load fully. Be sure
that there is no USB dongle is connected to computer yet. Insert the given
documentation CD and then double click the MY Computer icon on your
desktop. In my computer window, double click the CD Drive icon. Choose
WLAN USB Dongle folder and double click setup to execute Setup.exe. It
opens the InstallShield Wizard dialog box as shown next page.

Click Next to continue.
Step 2. Software License Agreement, click Yes to accept.

10
Step 3. Select Adapter Type. Please select Application & USB Drivers then click
Next.
Step 4. Click Next to search for alreadyinstalled components.

11
Step 5. Search for already installed components
Step 6. Choose Destination Location. Click Next

12
Step 7. Setup will add program icons to the Program Folder listed below. You may
type a new folder name, or select one from the existing folders list. Click
Next to continue.
Step 8. Select operating mode. Ad hoc mode provides communication between
wireless clients. Infrastructure mode provides communication between
wired and wireless clients (Requires an access point). Select
Infrastructure then click Next.

13
Step 9. ESSID is the name of a logical network group that your computer is about to
join. (It can be changed again at run time by the configuration utility).
.
Step 10. Click Next to start copying files.

3.2 Configuration Utility
WLAN USB dongle uses its own management software. All functions controlled by
user are provided by this application. When you plug WLAN USB dongle into the USB
port, a new icon-should appear in your icon tray
automatically wait a while. If the icon is in red, it means that WLAN USB Dongle
configuration is invalid or incomplete.
Double click on that icon the screen is shown below.
User can navigatethrough “cards”, by clicking or tapping them with a stylus.
In the following we explain the use and meanings of the various card.
Monitor
The field shows the association to available Access Point with Operating
Mode, Channel, Tx Rate Power Management mode and MAC Address of
WLAN USB Dongle. When the state is “Associated” means normal flow of
operation in infrastructure mode. The PC is connected to Access Point.
BSSID is chose in the form of hex digits.

“Change” / “Submit” button
This button becomes active only when one of the fields has been modified.
Pressing “Change” button applies the changed values to the driver. Than
pressing “Submit” button saves them to the registry.
Network Mode
This field allows you to select from a list of supported Network “Modes”. The
modes displayed will have two values: “Ad Hoc” and “Infrastructure”.
Ad Hoc -This is the 802.11b peer-to-peer mode of operation. All
communication is done from Client to Client without the use
of an Access Point. 802.11 Ad Hoc networking uses the
same SSID for establishing the wireless connection.
Infrastructure -This mode of operation requires the presence of an
802.11b Access Point. All communication is done via the
Access Point, which relays packets to other wireless Clients
in the BSS as well as to modes on a wired network such as
Ethernet.
Channel
There are 14 channels available. The channels differ from country to country.
Select the channel to be used.
SSID
SSID is the group name that will be shared by every member of your wireless
network. You will be able to connect with an Access Point, which has the
same SSID.
Tx Rate
The transmission rate at which the data packets are transmitted by client of
AP. You can set this to 1Mbps, 2Mbps, 5.5Mbps, 11Mbps or Fully Automatic.
Signal Strength / Link Quality
The Link Quality and Signal Strength bar graph 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. A label summarizes the
quality of the Link over the bar graph.

17
Statistics
To check the packets status, uses can press the “Statistics” tab and get
related statistical figures of data and management packets.

18
Site Survey
Click on the site survey tab, all access point within detectable range will be
found and their related information will be displayed.

19
Encryption
An encryption function can avoid unintended users who are not at the same
wireless LAN user group to access or get information. The “Encryption”
options allow you to enable 64-bit or 128-bit WEP (wired equivalent privacy)
encryption. If an encryption function is not needed, you can just simply tick
on the “Disable” box to disable it. By choosing this option you must define the
encryption key values of your choice. There are four 5 Hex digit encryption
keys available if you select 64 bit WEP or there are four 13 Hex digit
encryption keys available if you select 128 bit WEP.
WEP Key to use is a mechanism to enable the encryption function. After
enabling the WEP users need to select the authentication type, open system
key or shared key.
Open System with this setting any station in the WLAN can associate with
this device to receive and transmitted data.
Shared Key with this setting only stations using a share key encryption
identified by this device are allowed to associate with it.

20
Advanced
In advanced tab, you can change configuration setting such as Preamble
Type, Fragmentation Threshold, and RTS/CTS Threshold. Before selecting
Short Preamble, make sure that the other stations and AP’s are also
supporting this feature.
Preamble Type (Short/Long)
Preamble is the first subfield of PPDU, which is the appropriate frame format
for transmission to PHY (Physical layer). There are two options, Short
Preamble and Long Preamble. The Short Preamble option improves
throughput performance.
Fragmentation Threshold
The size at which packets will be fragmented. Choose a setting within a
range of 256 to 2346 bytes.
RTS/CTS Threshold
Minimum packet size requires an RTS/CTS. For packets smaller than this
threshold, and RTS/CTS is not sent and the packet is transmitted directly to
the WLAN. This is the option for the RTS/ CTS Threshold activation.
