1 Introduction
1.1 The 11Mbps Wireless LAN USB Dongle
The 11Mbp s Wireless LAN USB Dongle now has a new, higher-powered antenna that provides a
greater range than ever. The increased sensitivity helps filter out interference and notice to keep
your signal clear. Improved error correction in the chipset keeps you operating at higher
transmission rates for longer distances. And since you only need USB ports, you’re free to use
your other ports for additional accessories.
Plug-and-Play device, Windows 98SE/ME/2000/XP will automatically recognize the USB
wireless LAN Dongle and initiate the installation process. Upon successful installation, the USB
wireless LAN Dongle will communicate seamlessly with other wireless home and office
networking products.
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.
1.2 Feature

2 Network Configuration and Planning
2.1 Wireless LAN Basic
The adapter supports legacy Ethernet LAN network configuration options as defined by the IEEE
802.11b standards committee.
The adapter can be configured as:
Ad-Hoc for departmental or SOHO LANs.
Infrastructure for enterprise LANs.
LAN-Interconnection for point-to-point link as campus backbone.
2.2 Network Topology
Fig 2-1 Ad-Hoc Wireless LAN
An Ad-Hoc wireless LAN is a group of computers, each equipped with one WLAN adapter,
connected as an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must
be configured to share the same radio channel.
8
The adapter provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an infrastructure configuration. A group of adapter PC users and an
Access Point compose a Basic Service Set (BSS). Each adapter PC in a BSS can talk to any
computer in the wired LAN infrastructure via the Access Point.
An infrastructure configuration extends the accessibility of a adapter equipped PC to a wired
LAN, and doubles the effective wireless transmission range for 2 adapter PCs. Since the Access
Point is able to forward data within its BSS, the effective transmission range in an infrastructure
LAN is double.
Fig 2-2 Infrastructure Wireless LAN
The use of a unique ID in a BSS is essential. All adapter equipped PCs configured without
Fig 2-3 The effective transmission range
roaming options in independent BSS must be configured with a BSS ID corresponding to the
Access Point used in the BSS. Check your Access Point for its BSS ID or use the Access Point
Browser Utility program to determine the BSS ID
9
The infrastructure wireless LAN configuration is appropriate for enterprise-scale wireless access
to a central database, or as a wireless application for mobile users.
2.3 Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can
Fig 2-4 Roaming in an Extended Service Set (ESS)
be configured as an Extended Service Set (ESS). The continuous network allows users to roam
freely within an ESS. All adapter PCs and Access Point within one ESS must be configured with
the same ESS ID.
Before enabling an ESS with roaming capability, it is recommended to select a feasible radio
channel and optimum Access Point position. Proper Access Point positioning combined with a
clear radio signal will greatly enhance performance.

3 Installing the Drivers and Configuration Utility for Win98SE, ME, 2000
3.1 Running the Auto Driver/Utility Installation
Before installing your card, insert the Auto-Install CD into your CD-ROM driver. Unless you
have deactivated the auto-run feature of Windows, the screen shown in Fig 3-1 should appear
automatically.
If this screen doesn’t appear automatically, you can access the installation by clicking the Start
button and choosing Run. In the drop-down box provided type D:\Setup.exe (where D: is the
letterof your CD-ROM drive). Alternately, double-click My Computer and double-click the
Setup.exe iconin the folder that appears.
Fig 3-1 Auto-run feature of Windows
1. Click “Windows 98SE/ME/2000/XP Driver & Utility - USB” to install driver/utility for your USB
WLAN Dongle. You will see Welcome to the InstallShield Wizard for 802.11 Wireless LAN.
Click“Next >” (Fig 3-2).
2. After clicking “Next >”, components’ version of package will be shown on this screen. (Fig
3-3).
