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.
STA 2
STA 1
STA 3
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.
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 the Internet.

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 Wi ndows 98 SE to load fully. Be sure that
there is no USB dongle is connected to computer yet. Insert the given
Installation CD and then double click the MY Computer icon on your deskto p.
In my computer window, double click the CD Drive icon. In CD Drive, double
click Software , in the software folder, double click to execute Setup.exe, then
Click Next to continue.

Step 4. Click Next to search for already installed components.
Step 3. Select Adapter Type. Please select Application & USB Drivers then click
Next.
Step 5. Search for already installed components
11
Step 6. Choose Destination Location. Click Next
12
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.
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 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).

3.2 Configuration Utility
16
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 navigate through “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.
Network Mode
This field allows you to select from a list of supported Network “Modes”. The
modes displayed will have two values: “Infrastructure” and “802.11 Ad Hoc”
Infrastructure -This mo de 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.
802.11 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.
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.
“Change ” button
This button becomes active only when one of the fields has been modified.
Pressing this button applies the changed values to the driver and saves them
to the registry for the next time the PC boots up
Signal Strength / Link Quality
The Link Quality bar graph is only active when the node is in Infrastructure
Mode. The bar graph displays the quality of the link between the node and its
Access Point. A label summarizes the quality of the Link over the bar graph.

Statistics
18
To check the packets status, uses can press the “Statistics” tab and get
related statistical figures of data and management packets.
Site Survey
Click on the site survey tab, all access point within detectable range will be
found and their related information will be displayed.

Encryption
An encryption function can avoid unintended users who are not at the same
wireless LAN user group to access or get information. WEP 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.
Advanced
In advanced tab, you can cha nge 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.
