VI
Note and Caution in this manual are highlighted with graphics as below to indicate important
information.
Note
Contains related information text that corresponds to a topic.
Caution
Represents essential steps, actions, or messages that should not be ignored.
This User’s Manual contains information on how to install and configure your Wireless LAN
Card. From now on, we will guide you through the correct configuration steps to get your
device up and run.
7
Chapter 1 Introduction
This Wireless LAN Card enables your computer to access the Internet, share resources, such
as files or printers without being bound to the network wires. This card is fully compatible
with IEEE 802.11 standards, which means it can interoperate with devices from other vendors
that also follow this standard.
The 802.11b/g Wireless LAN Card can transmit data up to 54 Mbps. The 802.11b/g products
are backward compatible with 802.11b devices. Since the 802.11b standard has been widely
adopted in many devices and hotspots, you will still be able to be connected wherever you go.
802.11b/g Wireless LAN Card User's Manual
8
Wireless LAN Basics
This section contains some wireless network basics to help you better understand how the
product work together to create a wireless network.
Local Area Network (LAN)
Simply put, a LAN is a network that exists in a relatively limited area. A network is two or
more computers connected together sharing files and peripheral devices such as printers.
The Wireless LAN Card allows you to interact with other computers without having to run
cables normally associated with networks. This lets you move your computer around while
staying connected to your network.
There are two ways to use the Wireless LAN Card. One way is to connect directly to one or
more Wireless LAN Card equipped computers, forming an Ad-Hoc (Peer-to-Peer) wireless
network. The second way is to connect to an Access Point that gives you access to an existing
wired LAN, forming an Infrastructure wireless network.
Chapter 1 Introduction
9
Ad-Hoc Mode
Ad-Hoc mode offers peer-to-peer connections between workstations, allowing communication
between computers within range that have compatible wireless adapters installed. This mode
is typically used in a relatively small network. A typical Ad-Hoc network may look like
Figure 1-1 where all the wireless stations use the same Service Set Identity (SSID), channel,
WEP settings (if enabled).
Figure 1-1 Ad-Hoc Mode
802.11b/g Wireless LAN Card User's Manual
10
Interoperability between Wireless Stations
When set to use Ad-Hoc mode, your Wireless LAN Card can connect to another
standard-compatible Ad-Hoc peer. The interoperability between wireless stations is
summarized as follows:
! When operating in 802.11g mode, your target peer can be 802.11b or 802.11g compatible
wireless stations.
! An 802.11b/g device cannot communicate with 802.11a devices.
Infrastructure Mode
An Infrastructure network uses an Access Point or several Access Points as a gateway, linking
the wireless network to a wired LAN. As a result, portable workstations or desktops on your
wireless network have access to all of the features of your wired LAN including e-mail,
Internet access, network printers and files server.
To successfully associate with an Access Point, the wireless station must be set to use
Infrastructure mode and use the same Service Set Identity (SSID) and security settings (if
enabled) with the AP. It does not need to configure a channel since it will automatically
receive the channel assignment from the AP.
Chapter 1 Introduction
11
Note the following compatibility if your Wireless LAN Card is set to use Infrastructure mode:
! Your 802.11b/g card cannot connect to an 802.11a Access Point since 802.11a devices
are not compatible with 802.11b/g devices.
! Operating in 802.11b/g mode, you can connect to 802.11b or 802.11g compatible Access
Point.
Figure 1-2 Infrastructure Mode
802.11b/g Wireless LAN Card User's Manual
12
Roaming
Multiple Access Points can be installed to extend the wireless service coverage area for
seamless wireless access. Within an extended service area, all Access Points and wireless
clients must have the same Service Set Identity (SSID). Roaming among different Access
Points is controlled automatically to maintain the wireless connectivity at all times.
Figure 1-3 Roaming Across Multiple Access Points
Chapter 1 Introduction
13
802.11b and 802.11g
802.11b and 802.11g networks have their own features. Getting familiar with some of theses
features will help you better understand your device.
802.11b: This most widely adopted wireless standard operates in the 2.4GHz band. It supports
data rates of 1, 2, 5.5, and 11 Mbps. This standard employs Direct Sequence Spread Spectrum
(DSSS) technologies.
802.11g: This standard is a new emerged wireless networking standard. It provides data
transfer of up to 54 Mbps, up to 5 times faster than 802.11b.Since 802.11g operates on the
same frequency of 2.4 GHz as 802.11b, it is backwards compatible with existing 802.11b
devices. The benefit is that you can preserve the existing 802.11b infrastructure while
migrating to the new screaming fast 802.11g standard.
15
Chapter 2 Installing the Wireless LAN Card
This chapter describes the installation process for the driver and software for the Wireless
LAN Card. Proper driver installation is to allow the device to operate on your host computer
while the utility software, Wireless LAN Monitor Utility, is to help you configure and
monitor your Wireless LAN Card.
After completing the steps listed above, if you need to set up the TCP/IP protocol for the
Wireless LAN Card to communicate with your network, refer to “Appendix C Setting Up
TCP/IP” for details.

Glossary
802.11 802.11 refers to a family of specifications developed by the IEEE for wireless LAN
technology. 802.11 specifies an over-the-air interface between a wireless client and a
base station or between two wireless clients.
Access Point An internetworking device that seamlessly connects wired and wireless networks.
Access Points combined with a distributed system support the creation of multiple radio
cells that enable roaming throughout a facility.
Ad-Hoc
(Peer-to-Peer) An 802.11 networking framework in which devices or stations communicate directly
with each other, without the use of an Access Point (AP). Ad-hoc mode is useful for
establishing a network where wireless infrastructure does not exist or where wired
network services are not required. Ad-hoc mode is also referred to as peer-to-peer mode
or an Independent Basic Service Set (IBSS).
Bit A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single
binary, either 0 or 1.
Bluetooth Bluetooth is a computing and telecommunications industry specification that describes
how mobile phones, computers, and personal digital assistants (PDAs) can easily
interconnect with each other and with home and business phones and computers using a
802.11b/g Wireless LAN Card User's Manual
84
short-range wireless connection.
BSS Basic Service Set. In a network where an AP is connected to wired network and is
associates with a set of wireless stations, it is referred to as a BSS.
ESS Extended Service Set. An Extended Service Set (ESS) is a set of two or more BSSs that
form a single network. It’s basically a roaming wireless network.
Default Gateway The address used to forward all traffic that is not addressed to a station within a local
subnet.
Encryption The translation of data into a secret code. Encryption is the most effective way to
achieve data security. To read an encrypted file, you must have access to a secret key or
password that enables you to decrypt it.
Ethernet The most widely used medium access method, which is defined by the IEEE 802.3
standard. Ethernet is normally a shared media LAN; i.e., all the devices on the network
segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD
to run over 10BaseT cables.
Gateway A network component that interconnects networks with different, incompatible
communications protocols.
IEEE Abbreviation of Institute of Electrical and Electronics Engineers, pronounced I-triple-E.
Founded in 1884 as the AIEE, the IEEE was formed in 1963 when AIEE merged with
IRE. IEEE is an organization composed of engineers, scientists, and students. The IEEE
is best known for developing standards for the computer and electronics industry.
Infrastructure An 802.11 networking framework in which devices communicate with each other by
first going through an Access Point (AP). In Infrastructure mode, wireless devices can
Glossary
85
communicate with each other or can communicate with a wired network.
IP Internet Protocol. The standard protocol within TCP/IP that defines the basic unit of
information passed across an Internet connection by breaking down data messages into
packets, routing and transporting the packets over network connections, then
reassembling the packets at their destination. IP corresponds to the network layer in the
ISO/OSI model.
IP Address An IP Address is a 32-bit number that identifies each sender or receiver of information
sent across the Internet. An IP address has two parts: the identifier of a particular
network on the Internet and an identifier of the particular device (which can be a server
or a workstation) within that network.
LAN Local Area Network. A communication network that serves users within a defined
geographical area. The benefits include the sharing of Internet access, files, and
equipment, such as printers and storage devices. Special network cabling (such as
10BaseT) is often used to connect the PCs together.
MAC Address The MAC (Media Access Control) Address is a 12 digit Hexadecimal number that
uniquely identify your network adapter on the network.
Media The materials used to connect network devices, such as twisted-pair wire, coaxial cables,
or fiber optic cables. Some networks do not use physical connecting media;
communications are achieved via radio waves instead.
Mbps Stands for millions of bits per second or megabits per second and is a measurement for
data transmission.
Protocol The rules and encoding specifications for sending data.
802.11b/g Wireless LAN Card User's Manual
86
RF Radio Frequency, any frequency within the electromagnetic spectrum associated with
radio wave propagation. When an RF current is supplied to an antenna, an
electromagnetic field is created that then is able to propagate through space.
Roaming In an Infrastructure mode wireless network, roaming refers to the ability to move from
one AP coverage area to another without interruption in service or loss in connectivity.
SSID Service Set Identifier, up to 32-character unique identifier attached to the header of
packets sent over a WLAN that acts as a password when a mobile device tries to connect
to the BSS. The SSID differentiates one WLAN from another; so all access points and
all devices attempting to connect to a specific WLAN must use the same SSID. A device
will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is
also referred to as a Network Name because essentially it is a name that identifies a
wireless network.
Subnet Mask A value that defines whether your computer communicates only within your LAN or
communicates outside of your LAN, where it is routed out to the rest of the Internet. A
Subnet Mask that has the same first three components (for example, 255.255.255.0) is
the routing pattern for a Class C address.
TCP Transmission Control Protocol. The standard transport level protocol that provides the
full duplex, stream service on which many applications’ protocols depend. TCP allows a
process on one machine to send a stream of data to a process on another. Software
implementing TCP usually resides in the operating system and uses the IP to transmit
information across the network.
Topology The geometric arrangement of devices on a network. For example, devices can be
arranged in a ring, bus or star.
Glossary
87
WEP Wired Equivalent Privacy, a security protocol for wireless local area networks defined in
the 802.11b standard. WEP is designed to provide the same level of security as that of a
wired LAN. LANs are more secure than WLANs because LANs are somewhat
physically protected by their structure, having some or all part of the network inside a
building protected from unauthorized access. WLANs, which are over radio waves, do
not have the same physical structure and therefore are more vulnerable to tampering.
WEP aims to provide security by encrypting data over radio waves so that it is protected
as it is transmitted from one end point to another.
WLAN Wireless Local Area Network. A group of computers and devices that communicates
with each other wirelessly.
