1 Introduction
Thank you for purchasing Wireless Local Area Network (WLAN) PC Card.
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-freely.
Using radio frequency (RF) technology, WLAN devices 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.

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 wireless LAN PC cards, called a
BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to
communicate with each other directly.
STA 2
STA 1
STA 3
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.

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, it’s recommend that you set it as “Infrastructure”
mode to connect to the Internet.

3 Installation
This section describes the procedures for installing the Wireless LAN PC Card under
Windows 98SE, ME, 2000, XP and WinCE operating systems.
Before You Start
Before installation, please check your system in advance and ensure it meets the
minimum requirements as described below.
- Processor: Intel Celeron / Pentium II /Pentium III / Pentium IV; AMD Duron / Athlon
- Operating System: Microsoft Windows 98SE / ME / 2000 / XP, Linux
- System memory: 32MB at least
- Hard Drive Free Space: 5MB
Note:To prevent potential problems during installation, please use the auto-run
installation tool on the CD to finish the driver installation before you plug the
WLAN PC Card into the computer.
To use the WLAN PC Card with a computing device, the device must be equipped with
an internal or external PC Card Type II or Type III slot. All drivers and supporting
software for the WLAN PC Card must be installed and configured.
Ask your system administrator for the following information, which you may need
during driver installation:
•
•
•
•
Your Wireless LAN 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.
Every computer on a network is identified by a unique network address. There are two
methods to assign network addresses to computers on a TCP/IP network:
•
•
Static IP addressing
Dynamic IP addressing (DHCP)
In networks 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. Networks
6
WLAN PC Card User’s Guide
using static IP addresses are easy to set up and do not require additional network
management software.
In networks 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 addresses require setting up and running a DHCP Server.

bytes per second. These values are updated every two seconds.
Link Quality / Signal Strength
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, which can take on one of the following
values:
“Not Applicable”
“Poor”
“Fair”
“Good”
“Excellent”
The driver will start looking for a better Access Point if the Link Quality
becomes “Poor”. Link Quality is a measurement of receiving and transmitting
errors over the radio.
Configuration Tab
The Configuration Tab 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.

This field allows you to select from a list of supported Network Types. The
types displayed have two values: “Access Point” and “Peer-to-Peer”.
Access Point The infrastructure 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 nodes on a wired network such as Ethernet.
Peer-to-Peer This is the 802.11b Ad Hoc mode of operation. All
communication is done from Client to Client without the
use of an Access Point. 802.11 Ad Hoc network uses
the same SSID for establishing the wireless connection.

7 Glossary
IEEE 802.11 Standard
The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a
standard for the industry.
Access Point
An internetworking device that seamlessly connects wired and wireless networks
together.
Ad Hoc
An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN. Ad Hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO operation.
BSSID
A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must
be configured with the same BSSID.
DHCP
Dynamic Host Configuration Protocol - a method in which IP addresses are assigned
by server dynamically to clients on the network. DHCP is used for Dynamic IP
Addressing and requires a dedicated DHCP server on the network.
Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency
spectrum. The other method is frequency hopping. Direct sequence spreads the data
over one frequency range (channel) while frequency hopping jumps from one narrow
frequency band to another many times per second.
ESSID
An Infrastructure configuration could also support roaming capability for mobile
workers. More than one BSS can be configured as an Extended Service Set (ESS).
Users within an ESS could roam freely between BSSs while served as a continuous
connection to the network wireless stations and Access Points within an ESS must be
configured with the same ESSID and the same radio channel.
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users
must be wired to the network at all times to gain access.
63

Gateway
A gateway is a hardware and software device that connects two dissimilar systems,
such as a LAN and a mainframe. In Internet terminology, a gateway is another name
for a router. Generally a gateway is used as a funnel for all traffic to the Internet.
IEEE
Institute of Electrical and Electronics Engineers
Infrastructure
An integrated wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database,
or wireless application for mobile workers.
ISM Band
The FCC and their counterparts outside of the U.S. have set aside bandwidth for
unlicensed use in the so-called ISM (Industrial, Scientific and Medical) band.
Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide.
This presents a truly revolutionary opportunity to place convenient high-speed
wireless capabilities in the hands of users around the globe.
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network adapter
card connected by cable/air, that share applications, data, and peripherals. All
connections are made via cable or wireless media, but a LAN does not use telephone
services. It typically spans a single building or campus.
Network
A network is a system of computers that is connected. Data, files, and messages can
be transmitted over this network. Networks may be local or wide area networks.
PCMCIA
Personal Computer Memory Card International Association. Also a PCMCIA card is
also referred to PC Card.
Protocol
A protocol is a standardized set of rules that specify how a conversation is to take
place, including the format, timing, sequencing and/ or error checking.
64
WLAN PC Card User’s Guide
Roaming
In an infrastructure network, this is when a wireless PC moves out of range of the
previously connected access point and connects to a newly connected access point.
Throughout the network environment where access point are deployed, PCs can
always be connected regardless of where they are located or roam.
SSID
A Network ID unique to a network. Only clients and Access Points that share the same
SSID are able to communicate with each other. This string is case-sensitive.
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol is the network management protocol of TCP/IP.
In SNMP, agents-which can be hardware as well as software-monitor the activity in the
various devices on the network and report to the network console workstation. Control
information about each device is maintained in a structure known as a management
information block.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks with Static
IP address, 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, unless it is manually
changed.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research Projects Agency
(ARPA). It is widely used in corporate Internet works, because of its superior design
for WANs. TCP governs how packet is sequenced for transmission the network. The
term “TCP/IP” is often used generically to refer to the entire suite of related protocols.
Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone services and / or
fiber optic cabling. WANs may span a city, a state, a country, or even the world.
Wireless LAN (WLAN)
A wireless LAN does not use cable to transmit signals, but rather uses radio or
infrared to transmit packets through the air. Radio Frequency (RF) and infrared are the
65
WLAN PC Card User’s Guide
commonly used types of wireless transmission. Most wireless LANs use spread
spectrum technology. It offers limited bandwidth, usually under 11Mbps, and users
share the bandwidth with other devices in the spectrum; however, users can operate a
spread spectrum device without licensing from the Federal Communications
Commission (FCC)
