Introduction
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
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
Chapter 2
Basic Setup
This section describes how to install your NETGEAR 108 Mbps Wireless PCI Adapter WG311T
and set up basic wireless connectivity on your Wireless Local Area Network (WLAN). Advanced
wireless network configuration is covered in Chapter 3, “Configuration” in this manual.
Note: Indoors, computers can easily connect to 802.11 wireless networks at distances of
several hundred feet. Because walls do not always block wireless signals, others from
outside your immediate area could access your network. It is important to take
appropriate steps to secure your network from unauthorized access. The NETGEAR
108 Mbps Wireless PCI Adapter WG311T provides highly effective security features
which are covered in “Enabling Wireless Security Features” on page 3-8. Deploy the
security features appropriate to your needs.
What You Will Need Before You Begin
You need to verify that 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 pci adapter and connect.
Verify System Requirements
Before installing the NETGEAR 108 Mbps Wireless PCI Adapter WG311T, please make sure that
these minimum requirements have been met:
• Pentium® III class computer with an available PCI slot
• CD-ROM drive
• 20 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 WG311T driver software
Basic Setup
2-1
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
Observe Location and Range Guidelines
Computers can connect over 802.11g wireless networks indoors at a range which varies
significantly based on the physical location of the computer with the NETGEAR 108 Mbps
Wireless PCI Adapter WG311T. For best results, avoid potential sources of interference, such as:
•
•
•
Large metal surfaces
Microwaves
2.4 GHz Cordless phones
In general, 802.11g wireless devices can communicate through walls. However, if the walls are
constructed with concrete, or have metal, or metal mesh, the 802.11g effective range will decrease
if such materials are between the devices.
Two Basic Operating Modes
The WG311T Wireless PCI Adapter, like all 802.11b/g 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 AP 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. 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 WG311T Wireless PCI Adapter.
Infrastructure configuration procedures for basic network connectivity are covered below.
Advanced infrastructure configuration procedures and ad-hoc configuration are covered in
Chapter 3, “Configuration” of this manual.

Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
WG311T 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.
Your NETGEAR 108 Mbps Wireless PCI Adapter WG311T factory default basic settings are:
•
Network Name Service Set Identification (SSID): ANY — a special name which indicates the
first available network will be used
Note: In order for the WG311T Wireless PCI Adapter to communicate with a wireless access
point or wireless adapter, all devices must be configured with the same wireless network name
(SSID).
•
Network Mode (Infrastructure or Ad-Hoc): Infrastructure
•
Data security WEP encryption: Disabled

software might not be installed and configured properly on your computers. Please refer to
“Preparing Your Computers for TCP/IP Networking” on page C-1.
Connecting to Another PC in Ad-Hoc Mode
The computer-to-computer setting of the WG311T uses Ad-Hoc mode. Ad-Hoc mode is an 802.11
networking framework in which devices or computers communicate directly with each other,
without the use of an access point. For example, this mode is used when two Windows computers
are configured with file and print sharing enabled and you want to exchange files directly between
them.
How to Configure an Ad-Hoc Mode Profile
Note: Ad-Hoc mode will not work using DHCP settings. Ad-Hoc mode requires either static IP
addresses (such as 192.168.0.1) or other appropriate Windows networking configuration
parameters such as adding IPX protocol support. For instructions on setting up static IP addresses
or IPX protocol settings on a Windows PC, refer to the PC Networking Tutorial included on the
NETGEAR 108 Mbps Wireless PCI Adapter WG311T Resource CD.

Wireless Networking Basics
This chapter provides an overview of Wireless networking.
Wireless Networking Overview
The WG311T Wireless PCI Adapter conforms to the Institute of Electrical and Electronics
Engineers (IEEE) 802.11b standard for wireless LANs (WLANs) and a product update will bring
the WG311T into conformance to the 802.11g standard when it is ratified. On an 802.11b or g
wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is
transmitted in the unlicensed radio spectrum at 2.4GHz. 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 802.11g auto rate sensing rates are 1, 2,
5.5, 6, 9, 12, 18, 24, 36, 48, and 54 Mbps.
The 802.11 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 802.11 devices. The 802.11 standard offers two methods for configuring a
wireless network - Ad-Hoc and infrastructure.
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.
Wireless Networking Basics
B-1
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
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.
Network Name: 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 ESSID is
used, but may still be referred to as SSID.
An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of 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
The absence of a physical connection between nodes makes the wireless links vulnerable to
eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11
standard has defined two types of authentication methods, Open System and Shared Key. With
Open System authentication, a wireless PC can join any network and receive any messages that are
not encrypted. 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 an
Open System network.
Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices 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.
B-2
Wireless Networking Basics
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
802.11 Authentication
The 802.11 standard defines several services that govern how two 802.11 devices communicate.
The following events must occur before an 802.11 Station can communicate with an Ethernet
network through an access point such as the one built in to the WG311T:
1.
Turn on the wireless station.
2.
The station listens for messages from any access points that are in range.
3.
The station finds a message from an access point that has a matching SSID.
4.
The station sends an authentication request to the access point.
5.
The access point authenticates the station.
6.
The station sends an association request to the access point.
7.
The access point associates with the station.
8.
The station can now communicate with the Ethernet network through the access point.
An access point must authenticate a station before the station can associate with the access point or
communicate with the network. The IEEE 802.11 standard defines two types of authentication:
Open System and Shared Key.
•
Open System Authentication allows any device to join the network, assuming that the device
SSID matches the access point SSID. Alternatively, the device can use the “ANY” SSID
option to associate with any available Access Point within range, regardless of its SSID.
•
Shared Key Authentication requires that the station and the access point have the same WEP
Key to authenticate. These two authentication procedures are described below.
Open System Authentication
The following steps occur when two devices use Open System Authentication:
1.
The station sends an authentication request to the access point.
2.

Shared Key Authentication
The following steps occur when two devices use Shared Key Authentication:
1.
The station sends an authentication request to the access point.
2.
The access point sends challenge text to the station.
3.
The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and
sends the encrypted text to the access point.
4.
The access point decrypts the encrypted text using its configured WEP Key that corresponds
to the station’s default key. The access point compares the decrypted text with the original
challenge text. If the decrypted text matches the original challenge text, then the access point
and the station share the same WEP Key and the access point authenticates the station.
5.
The station connects to the network.
If the decrypted text does not match the original challenge text (i.e., the access point and station do
not share the same WEP Key), then the access point will refuse to authenticate the station and the
station will be unable to communicate with either the 802.11 network or Ethernet network.
This process is illustrated in below.

Overview of WEP Parameters
Before enabling WEP on an 802.11 network, you must first consider what type of encryption you
require and the key size you want to use. Typically, there are three WEP Encryption options
available for 802.11 products:
1. Do Not Use WEP: The 802.11 network does not encrypt data. For authentication purposes, the
network uses Open System Authentication.
2. Use WEP for Encryption: A transmitting 802.11 device encrypts the data portion of every
packet it sends using a configured WEP Key. The receiving 802.11b device decrypts the data using
the same WEP Key. For authentication purposes, the 802.11b network uses Open System
Authentication.
3. Use WEP for Authentication and Encryption: A transmitting 802.11 device encrypts the data
portion of every packet it sends using a configured WEP Key. The receiving 802.11 device
decrypts the data using the same WEP Key. For authentication purposes, the 802.11 network uses
Shared Key Authentication.
Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key
Authentication without data encryption).

B-5
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
Key Size
The IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit.
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.
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.
128-bit encryption is stronger than 40-bit encryption, but 128-bit encryption may not be available
outside of the United States due to U.S. export regulations.
When configured for 40-bit encryption, 802.11 products typically support up to four WEP Keys.
Each 40-bit WEP Key is expressed as 5 sets of two hexadecimal digits (0-9 and A-F). For
example, “12 34 56 78 90” is a 40-bit WEP Key.
When configured for 128-bit encryption, 802.11b products typically support four WEP Keys but
some manufacturers support only one 128-bit key. The 128-bit WEP Key is expressed as 13 sets of
two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90 AB CD EF 12 34 56 78 90”
is a 128-bit WEP Key.
Note: Typically, 802.11 access points can store up to four 128-bit WEP Keys but some 802.11
client adapters can only store one. Therefore, make sure that your 802.11 access and client
adapters configurations match.
WEP Configuration Options
The WEP settings must match on all 802.11 devices that are within the same wireless network as
identified by the SSID. In general, if your mobile clients will roam between access points, then all
of the 802.11 access points and all of the 802.11 client adapters on the network must have the same
WEP settings.
B-6
Wireless Networking Basics
Installation Guide for the NETGEAR 108 Mbps Wireless PCI Adapter WG311T
Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter
in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client
adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.
Note: The AP and the client adapters can have different default WEP Keys as long as the keys are
in the same order. In other words, the AP can use WEP key 2 as its default key to transmit while a
client adapter can use WEP key 3 as its default key to transmit. The two devices will communicate
as long as the AP’s WEP key 2 is the same as the client’s WEP key 2 and the AP’s WEP key 3 is
the same as the client’s WEP key 3.
Wireless Channels
IEEE 802.11b and g wireless nodes communicate with each other using radio frequency signals in
the ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring
channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending
signals using a particular channel will utilize frequency spectrum 12.5 MHz 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.
Wireless Networking Basics

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
NETGEAR 108 Mbps Wireless PCI Adapter WG311T.
For adding file and print sharing to your network, please consult the Windows help information
included with the version of Windows installed on each computer on your network.
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 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.
