A Road Map for ‘How to Get There From Here’
The introduction and adoption of any new technology can be a difficult process.
Wireless technology has removed one of the barriers to networking: running
wires. It allows more people to try networking while at the same time exposes
them to the inherent complexity of networking. General networking concepts, set
up, and maintenance can be difficult to understand. In addition, wireless
technology adds issues, such as range, interference, signal quality, and security to
the picture.
To help overcome potential barriers to successfully using wireless networks, the
table below identifies how to accomplish such things as connecting to a wireless
network, assuring appropriate security measures are taken, browsing the Internet
through your wireless connection, exchanging files with other computers and
using printers in the combined wireless and wired network.

Introduction
MA401.book Page 1 Tuesday, October 8, 2002 4:08 PM
Chapter 2
Installing the
MA401 802.11b Wireless PC Card
This chapter describes how to set up your MA401 802.11b Wireless PC Card for
wireless connectivity on your Wireless Local Area Network (WLAN).
Note: Computers can connect over 802.11b wireless networks at a
range of several hundred feet indoors. With this distance, and
because walls do not always block wireless signals, others outside your
immediate area could access your network. Therefore, it is important to
take appropriate steps to secure your network from unauthorized access.
The MA401 802.11b Wireless PC Card provides highly effective
security features which are covered in “Enabling Basic Wireless
Security Features“ on page 3-1. Netgear strongly recommends you
deploy the security features appropriate to your needs.
What You Will Need Before You Begin
You need to verify your computer meets the minimum system requirements and
identify the wireless network configuration settings of the WLAN where you will
connect before you can configure your wireless pc card and connect.
Installing the MA401 802.11b Wireless PC Card
2-1
MA401.book Page 2 Tuesday, October 8, 2002 4:08 PM
Reference Guide for the Model MA401 802.11b Wireless PC Card
Verify System Requirements
Before installing the MA401 802.11b Wireless PC Card, please make sure
that these minimum requirements have been met:
•
•
•
•
You must have a Pentium Class notebook computer with an available
PCMCIA or Cardbus slot.
A CD-ROM drive.
5 Mbytes of free hard disk space.
Some versions of Windows may ask for the original Windows operating
system installation files to complete the installation of the MA401 driver
software.
Observe Location and Range Guidelines
Computers can connect over 802.11b wireless networks indoors at a maximum
range of approximately 500 feet. However, the operating distance or range of your
wireless connection can vary significantly based on the physical location of the
computer with the MA401 802.11b Wireless PC Card. For best results, avoid
potential sources of interference, such as:
•
•
•
Large metal surfaces
Microwaves
2.5 GHz Cordless phones
In general, 802.11b wireless devices can communicate through walls. However, if
the walls are constructed with concrete, or have metal, or metal mesh, the 802.11b
wireless network effective range will decrease if such materials are between the
devices.

MA401.book Page 3 Tuesday, October 8, 2002 4:08 PM
Reference Guide for the Model MA401 802.11b Wireless PC Card
Two Basic Operating Modes
The MA401 PC Card, like all 802.11b adapters, can operate in the following two
basic modes:
•
Infrastructure Mode: An 802.11 networking framework in which devices
and computers communicate with each other by first going through an Access
Point (AP).
For example, this mode is used when computers in a house connect to an
Access Point that is attached to a router which lets multiple computers share a
single Cable or DSL broadband Internet connection.
•
Ad-Hoc Mode: An 802.11 networking framework in which devices or
computers communicate directly with each other, without the use of an
access point (AP).
For example, Ad-Hoc Mode is used when two Windows computers are
configured with file and print sharing enabled and you want to
exchange files directly between them.
Both of these configuration options are available with the MA401 PC Card.
MA401 Default Wireless Configuration Settings
If this is a new wireless network installation, use the factory default settings to set
up the network and verify wireless connectivity. If this is an addition to an
existing wireless network, you will need to identify the wireless configuration and
security parameters already defined.
Note: All NETGEAR, Inc. 802.11b wireless access products use the same factory
settings as the MA401 and will work without any configuration changes.
Your MA401 802.11b Wireless PC Card factory default basic settings are:
•
•
SSID: Wireless
Note: In order for the MA401 PC Card to communicate with a wireless access
point or wireless adapter, all devices must be configured with the same SSID.
Mode (Infrastructure or Ad Hoc): Infrastructure

Chapter 3
Protecting Your Wireless Connection
The absence of a physical connection between nodes makes wireless links
vulnerable to information theft. This chapter describes how to use the basic
security features of the MA401 802.11b Wireless PC Card to protect your
connection.
Enabling Basic Wireless Security Features
There are several ways you can strengthen the security of your wireless
connection.
•
Enable Wired Equivalent Privacy (WEP) encryption of the wireless data
communications.
•
Change the factory default SSID setting of the MA401 802.11b Wireless PC
Card.
In addition to the MA401 wireless security features, you should also configure
appropriate LAN network security features such as requiring a user name and
password to access the shared resources in your network.
Netgear strongly recommends that, at a minimum, you configure your wireless
network to use an SSID other than the default setting.The procedures below
identify how to change the SSID and WEP encryption settings of your MA401
802.11b Wireless PC Card.

Identifying the Wireless Network Name (SSID) and
WEP Security Settings
1.
For a new wireless network, print this form, fill in the configuration
parameters and put it in a safe place for possible future reference.
For an existing wireless network, print this form and fill in the configuration
parameters. The person who set up or is responsible for the network will be
able to provide this information.
•
Wireless Network Name (SSID): The Service Set Identification (SSID)
identifies the wireless local area network. Wireless is the default MA401
SSID. However, you may customize it by using up to 32 alphanumeric
characters. Netgear recommends that you write your customized SSID on
the line below.
Note: The SSID in the wireless Access Point is the SSID you configure in
the wireless pc card. For the access point and wireless nodes to
communicate with each other, all must be configured with the same SSID.
Wireless network name (SSID): ______________________________
•
WEP Security Encryption key: The default WEP encryption key number
is 1, and the default key size is 64 bits.
Note: The key number as well as the key value used by both the Wireless
Access Point and wireless nodes must be the same. If they are different,
you will not be able to connect.
WEP Encryption Key Size, circle one: 64 or 128 bits
WEP Encryption Passphrase, if used: ____________________________
A Passphrase is used to automatically generate the WEP hexadecimal
numbers for the key. If the wireless network Access Point uses a
Passphrase, you can also use that here. Otherwise, you will have to
manually enter the hexadecimal numbers.
WEP Hexadecimal Numbers: ______________________________
The WEP Hexadecimal Numbers are needed if a Passphrase is not used in
the wireless network Access Point but rather if the key is manually
entered.

802.11b Wireless Networking Basics
This chapter provides an overview of IP networks, routing, and wireless
networking.
Related Publications
As you read this document, you may be directed to various RFC documents for
further information. An RFC is a Request For Comment (RFC) published by the
Internet Engineering Task Force (IETF), an open organization that defines the
architecture and operation of the Internet. The RFC documents outline and define
the standard protocols and procedures for the Internet. The documents are listed
on the World Wide Web at www.ietf.org and are mirrored and indexed at many
other sites worldwide.
Wireless Networking
The MA401 Wireless PC Card conforms to the Institute of Electrical and
Electronics Engineers (IEEE) 802.11b standard for wireless LANs (WLANs). On
an 802.11b wireless link, data is encoded using direct-sequence spread-spectrum
(DSSS) technology and is transmitted in the unlicensed radio spectrum at 2.5GHz.
The maximum data rate for the wireless link is 11 Mbps, but it will automatically
back down from 11 Mbps to 5.5, 2, and 1 Mbps when the radio signal is weak or
when interference is detected.
The 802.11b standard is also called Wireless Ethernet or Wi-Fi by the Wireless
Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry
standard group promoting interoperability among 802.11b devices.
Wireless Network Configuration
The 802.11b standard offers two methods for configuring a wireless network - ad
hoc and infrastructure.
802.11b Wireless Networking Basics
B-1
MA401.book Page 2 Tuesday, October 8, 2002 4:08 PM
Reference Guide for the Model MA401 802.11b Wireless PC Card
Ad-hoc Mode (Peer-to-Peer Workgroup)
In an ad hoc network, computers are brought together as needed; thus, there is no
structure or fixed points to the network - each node can generally communicate
with any other node. There is no Access Point involved in this configuration. This
mode enables you to quickly set up a small wireless workgroup and allows
workgroup members to exchange data or share printers as supported by Microsoft
Networking in the various Windows operating systems. Some vendors also refer
to ad hoc networking as Peer-to-Peer group networking.
In this configuration, network packets are directly sent and received by the
intended transmitting and receiving stations. As long as the stations are within
range of one another, this is the easiest and least expensive way to set up a
wireless network.
Infrastructure Mode
With a wireless Access Point, you can operate the wireless LAN in the
infrastructure mode. This mode provides wireless connectivity to multiple
wireless network devices within a fixed range or area of coverage, interacting
with wireless nodes via an antenna.
In the infrastructure mode, the wireless access point converts airwave data into
wired Ethernet data, acting as a bridge between the wired LAN and wireless
clients. Connecting multiple Access Points via a wired Ethernet backbone can
further extend the wireless network coverage. As a mobile computing device
moves out of the range of one access point, it moves into the range of another. As
a result, wireless clients can freely roam from one Access Point domain to another
and still maintain seamless network connection.
Extended Service Set Identification (ESSID)
The Extended Service Set Identification (ESSID) is one of two types of Service
Set Identification (SSID). In an ad-hoc wireless network with no access points, the
Basic Service Set Identification (BSSID) is used. In an infrastructure wireless
network that includes an access point, the Extended Service Set Identification
(ESSID) is used, but may still be referred to as SSID.

802.11b Wireless Networking Basics
MA401.book Page 3 Tuesday, October 8, 2002 4:08 PM
Reference Guide for the Model MA401 802.11b Wireless PC Card
An SSID is a thirty-two character (maximum) alphanumeric key identifying the
wireless local area network. Some vendors refer to the SSID as network name. For
the wireless devices in a network to communicate with each other, all devices
must be configured with the same SSID.
Authentication and WEP Encryption
The absence of a physical connection between nodes makes the wireless links
vulnerable to eavesdropping and information theft. To provide certain level of
security, the IEEE 802.11 standard defines two types of authentication methods:
•
Open System -- Open System authentication is a null algorithm which
requires an system identifier but does not encrypt the wireless data. With
Open System authentication, a wireless PC can join any network merely by
providing the SSID and receive any messages that are not encrypted.
•
Shared Key -- Shared Key authentication is an algorithm where both the
transmitting node and the receiving node share an authentication key to
perform a checksum on the original message. With Shared Key
authentication, only those PCs that possess the correct authentication key can
join the network.
By default, IEEE 802.11 wireless devices operate in open system network mode.
That is, they do not encrypt the data being transmitted over the wireless network.
Wired Equivalent Privacy (WEP)
Wired Equivalent Privacy (WEP) data encryption is utilized when the wireless
nodes or access points are configured to operate in Shared Key authentication
mode. There are two shared key methods implemented in most commercially
available products, 64-bit and 128-bit WEP data encryption.
The 64-bit WEP data encryption method, allows for a five-character (40-bit)
input. Additionally, 24 factory-set bits are added to the forty-bit input to generate
a 64-bit encryption key. The 24 factory-set bits are not user-configurable. This
encryption key will be used to encrypt/decrypt all data transmitted via the wireless
interface. Some vendors refer to the 64-bit WEP data encryption as 40-bit WEP
data encryption since the user-configurable portion of the encryption key is 40 bits
wide.

B-3
MA401.book Page 4 Tuesday, October 8, 2002 4:08 PM
Reference Guide for the Model MA401 802.11b Wireless PC Card
The 128-bit WEP data encryption method consists of 104 user-configurable bits.
Similar to the forty-bit WEP data encryption method, the remaining 24 bits are
factory set and not user configurable. Some vendors allow passphrases to be
entered instead of the cryptic hexadecimal characters to ease encryption key entry.
Wireless Channel Selection
IEEE 802.11 wireless nodes communicate with each other using radio frequency
signals in the ISM (Industrial, Scientific, and Medical) band between 2.4Ghz and
2.5Ghz. Neighboring channels are 5Mhz apart. However, due to spread spectrum
effect of the signals, a node sending signals using a particular channel will utilize
frequency spectrum12.5Mhz above and below the center channel frequency. As a
result, two separate wireless networks using neighboring channels (for example,
channel 1 and channel 2) in the same general vicinity will interfere with each
other. Applying two channels that allow the maximum channel separation will
decrease the amount of channel cross-talk, and provide a noticeable performance
increase over networks with minimal channel separation.

Note: The available channels supported by the wireless products in various
countries are different.
The preferred channel separation between the channels in neighboring wireless
networks is 25 MHz (5 channels). This means that you can apply up to three
different channels within your wireless network. There are only 11 usable wireless
channels in the United States. It is recommended that you start using channel 1
and grow to use channel 6, and 11 when necessary, as these three channels do not
overlap.

Appendix C
Preparing Your PCs for Network Access
This appendix describes how to prepare your PCs to connect to the Internet
through the MA401 802.11b Wireless PC Card.
Preparing Your Computers for TCP/IP Networking
Computers access the Internet using a protocol called TCP/IP (Transmission
Control Protocol/Internet Protocol). Each computer on your network must have
TCP/IP installed and selected as its networking protocol. If a Network Interface
Card (NIC) is already installed in your PC, then TCP/IP is probably already
installed as well.
Most operating systems include the software components you need for
networking with TCP/IP. Windows® 95 or later includes the software components
for establishing a TCP/IP network.
In your TCP/IP network, each PC and the wireless access point must be assigned a
unique IP addresses. Each PC must also have certain other TCP/IP configuration
information such as a subnet mask (netmask), a domain name server (DNS)
address, and a default gateway address. In most cases, you should install TCP/IP
so that the PC obtains its specific network configuration information
automatically from a DHCP server during startup.
Configuring Windows 95, 98, and ME for TCP/IP
Networking
As part of the PC preparation process, you may need to install and configure
TCP/IP on your PC. Before starting, locate your Windows CD; you may need to
insert it during the TCP/IP installation process.
