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.

Chapter 3
Basic Setup
This section describes how to install your NETGEAR RangeMax™ Wireless PCI Adapter
WPN311 and set up basic wireless connectivity on your Wireless Local Area Network (WLAN).
Advanced wireless network configuration is covered in Chapter 4, “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
RangeMax™ Wireless PCI Adapter WPN311 provides highly effective security
features which are covered in “Enabling Wireless Security Features” on page 4-8.
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 pc adapter and connect.
Verify System Requirements
Before installing the NETGEAR RangeMax™ Wireless PCI Adapter WPN311, please make sure
that these minimum requirements have been met:
•
•
•
•
Pentium® III class computer with an available PCI slot
CD 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 WPN311 driver software
B a sic S e tu p

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
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 RangeMax™
Wireless PCI Adapter WPN311. 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 WPN311 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 WPN311 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 4, “Configuration” of this manual.
WPN311 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.

Monitor wireless network connections.
•
Save your settings in configuration profiles.
The section below introduces these capabilities of the configuration utility.
Using Configuration Profiles
The WPN311 configuration utility uses profiles to store all the configuration settings for a
particular wireless network. You can store multiple profiles and recall the one which matches
the network you want to join.
C on figu ra tion
4 -1
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
For example, if you use your PC to connect to a wireless network in an office and a wireless
network in your home, you can create a profile for each wireless network. Then, you can easily
load the profile that has all the configuration settings you need to join the network you are using at
the time.
There are two types of wireless network connections you can configure:
•
Infrastructure Mode — uses the 802.11 infrastructure mode.
•
Ad-Hoc Mode — uses the 802.11 ad-hoc mode

Connecting to Another PC in Ad-Hoc Mode
The computer-to-computer setting of the WPN311 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

How to Configure WPA-PSK Encryption Security
Wi-Fi Protected Access (WPA) is wireless security with far greater protection than WEP.
WPA-PSK (pre-shared key) uses encryption of a shared key as the starting point. WPA has a
significant advantages over WEP — an encryption key differing in every packet. It is extremely
difficult for hackers to read messages even if they have intercepted the data.

Transmit Power: Lowering the output power level lets you reduce the chance of interference
with other nearby access points but reduces the range of your adapter.
•
Wireless Mode: Select the wireless protocols you will use. Depending on your wireless
adapter, you can choose some or all of the available 802.11 wireless protocols. Note that, if the
wireless network you are communicating with uses the 108Mb Turbo mode, you must include
that in your selection.
•
Fragmentation Threshold: This is the maximum packet size used for fragmentation. Packets
larger than the size programmed in this field will be fragmented. The Fragment Threshold
value must be larger than the RTS Threshold value.
•
RTS/CTS Threshold: RTS is request to send and CTS is clear to send; their purpose is to
avoid collisions. RTS/CTS will be enabled if the data frame size is larger than the threshold
value set here. The maximum frame size is 2346 octets, so if the threshold is 2346, RTS/CTS
will be disabled.
Note: This setting is reserved for wireless testing and advanced configuration only. Do not
change this setting unless you are sure you need to. The primary reason for implementing
RTS/CTS is to minimize collisions between hidden stations. This occurs when users and
access points are spread out and a high number of retransmissions occur on the wireless LAN.

If the access point (AP) is WPA-PSK protected, you will need to have the correct WPA-PSK
passphrase. Otherwise, the WPN311 will still be connected to the previous access point and
you will not be able to change to the WPA-PSK access point.
•
If the access point is WEP protected (either 64 or 128 bit encryption), you will be prompted to
enter the WEP encryption security information.
The WPN311 is not getting an IP address
You probably upgraded your WPN311 software and did not reboot your system.
To get an IP address assigned, you can either restart your computer or choose another access point
to connect to. If there are no additional access points for you to choose from, restart your system
and connect to your desired access point again.
Note: It does not usually help to shut down the utility or disable/enable the card.
Wi-Fi Protected Access (WPA) Questions
Why is my WPN311 not connecting to my WPA router?
I thought I chose my WPA router in XP Zero Configuration’s Available networks and it is showing
other devices in the Preferred networks list, why is my WPN311 not connecting to my WPA
router?
Check your Preferred networks and remove the other non-WPA devices from the list. Only leave
your WPA router in the list and try connecting again.
Why is the icon in the System Tray flashing Green to Red alternately?
I thought I got my WPN311 WPA connection – a green icon in the SystemTray.
Although you have use XP zero configuration utility for your WPA settings, the open “Green-Red”
flashing icon indicates that you might have entered the incorrect WPA secret key. Assure that the
WPA settings are configured correctly on both the Radius Server and the Router. In addition, you
may also check the Radius’ port number on the Radius server and the router.
How do I know that my WPN311 WPA is working?
Try browsing an Internet site to see if your WPA router has an Internet connection. Or try pinging
the Radius server through the WPA router.

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
Why is the WAN port not working after configuring WPA?
I can ping the WPA router but there is no Internet connection. I know that the WAN port was not
working before my WPA connection.
One thing to check is the DHCP on the WPA router. Make sure the DHCP server or DHCP client
option is correctly set. You may also check the Radius server’s DHCP settings.
Note: For all WPA questions, please refer to Microsoft’s Help documentation for additional WPA
related information and how to configure WPA using Windows XP Zero configuration utility.

Wireless Networking Basics
This chapter provides an overview of Wireless networking.
Wireless Networking Overview
The WPN311 Wireless PCI Adapter conforms to the Institute of Electrical and Electronics
Engineers (IEEE) 802.11b and 802.11 g standards for wireless LANs (WLANs)WPN311. 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, 54, and 108 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.
W ire le ss N e tworkin g B a sics
B -1
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
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.

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
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 WPN311:
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. The access point authenticates the station.
3. The station associates with the access point and joins the network.
This process is illustrated in below.

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 802.11 device decrypts the data using
the same WEP Key. For authentication purposes, the 802.11 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).

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, 802.11 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
W ireless N etworkin g B a sics
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
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 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.
WPA Wireless Security
Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security
enhancements that increase the level of data protection and access control for existing and future
wireless LAN systems.
B -8
W ireless N etworkin g B a sics
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
The IEEE introduced the WEP as an optional security measure to secure 802.11b (Wi-Fi) WLANs,
but inherent weaknesses in the standard soon became obvious. In response to this situation, the
Wi-Fi Alliance announced a new security architecture in October 2002 that remedies the
shortcomings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed
to work with existing 802.11 products and offers forward compatibility with 802.11i, the new
wireless security architecture being defined in the IEEE.
WPA offers the following benefits:
•
•
•
•
Enhanced data privacy
Robust key management
Data origin authentication
Data integrity protection
The Wi-Fi Alliance is now performing interoperability certification testing on Wi-Fi Protected
Access products. Starting August of 2003, all new Wi-Fi certified products will have to support
WPA. NETGEAR will implement WPA on client and access point products and make this
available in the second half of 2003. Existing Wi-Fi certified products will have one year to add
WPA support or they will lose their Wi-Fi certification.
The 802.11i standard is currently in draft form, with ratification due at the end of 2003. While the
new IEEE 802.11i standard is being ratified, wireless vendors have agreed on WPA as an
interoperable interim standard.
How Does WPA Compare to WEP?
WEP is a data encryption method and is not intended as a user authentication mechanism. WPA
user authentication is implemented using 802.1x and the Extensible Authentication Protocol
(EAP). Support for 802.1x authentication is required in WPA. In the 802.11 standard, 802.1x
authentication was optional. For details on EAP specifically, refer to IETF's RFC 2284.
With 802.11 WEP, all access points and client wireless adapters on a particular wireless LAN must
use the same encryption key. A major problem with the 802.11 standard is that the keys are
cumbersome to change. If you do not update the WEP keys often, an unauthorized person with a
sniffing tool can monitor your network for less than a day and decode the encrypted messages.
Products based on the 802.11 standard alone offer system administrators no effective method to
update the keys.

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
For 802.11, WEP encryption is optional. For WPA, encryption using Temporal Key Integrity
Protocol (TKIP) is required. TKIP replaces WEP with a new encryption algorithm that is stronger
than the WEP algorithm, but that uses the calculation facilities present on existing wireless devices
to perform encryption operations. TKIP provides important data encryption enhancements
including a per-packet key mixing function, a message integrity check (MIC) named Michael, an
extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. Through
these enhancements, TKIP addresses all of the known WEP vulnerabilities.
How Does WPA Compare to IEEE 802.11i?
WPA will be forward compatible with the IEEE 802.11i security specification currently under
development. WPA is a subset of the current 802.11i draft and uses certain pieces of the 802.11i
draft that are ready to bring to market today, such as 802.1x and TKIP. The main pieces of the
802.11i draft that are not included in WPA are secure IBSS (Ad Hoc mode), secure fast handoff
(for specialized 802.11 VoIP phones), as well as enhanced encryption protocols, such as
AES-CCMP. These features are either not yet ready for market or will require hardware upgrades
to implement.
What are the Key Features of WPA Security?
The following security features are included in the WPA standard:
•
•
•
WPA Authentication
WPA Encryption Key Management
–
Temporal Key Integrity Protocol (TKIP)
–
Michael message integrity code (MIC)
–
AES Support (to be phased in)
Support for a Mixture of WPA and WEP Wireless Clients, but mixing WEP and WPA is
discouraged
These features are discussed below.
WPA addresses most of the known WEP vulnerabilities and is primarily intended for wireless
infrastructure networks as found in the enterprise. This infrastructure includes stations, access
points, and authentication servers (typically RADIUS servers). The RADIUS server holds (or has
access to) user credentials (for example, user names and passwords) and authenticates wireless
users before they gain access to the network.

W ire less N e tworkin g B a sics
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311
The strength of WPA comes from an integrated sequence of operations that encompass 802.1X/
EAP authentication and sophisticated key management and encryption techniques. Its major
operations include:
•
Network security capability determination. This occurs at the 802.11 level and is
communicated through WPA information elements in Beacon, Probe Response, and (Re)
Association Requests. Information in these elements includes the authentication method
(802.1X or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES).
The primary information conveyed in the Beacon frames is the authentication method and the
cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared
key is an authentication method that uses a statically configured pass phrase on both the
stations and the access point. This obviates the need for an authentication server, which in
many home and small office environments will not be available nor desirable. Possible cipher
suites include: WEP, TKIP, and AES (Advanced Encryption Standard). We talk more about
TKIP and AES when addressing data privacy below.
•
Authentication. EAP over 802.1X is used for authentication. Mutual authentication is gained
by choosing an EAP type supporting this feature and is required by WPA. 802.1X port access
control prevents full access to the network until authentication completes. 802.1X
EAPOL-Key packets are used by WPA to distribute per-session keys to those stations
successfully authenticated.
The supplicant in the station uses the authentication and cipher suite information contained in
the information elements to decide which authentication method and cipher suite to use. For
example, if the access point is using the pre-shared key method then the supplicant need not
authenticate using full-blown 802.1X. Rather, the supplicant must simply prove to the access
point that it is in possession of the pre-shared key. If the supplicant detects that the service set
does not contain a WPA information element then it knows it must use pre-WPA 802.1X
authentication and key management in order to access the network.
•
Key management. WPA features a robust key generation/management system that integrates
the authentication and data privacy functions. Keys are generated after successful
authentication and through a subsequent 4-way handshake between the station and Access
Point (AP).
•
Data Privacy (Encryption). Temporal Key Integrity Protocol (TKIP) is used to wrap WEP in
sophisticated cryptographic and security techniques to overcome most of its weaknesses.
•
Data integrity. TKIP includes a message integrity code (MIC) at the end of each plaintext
message to ensure messages are not being spoofed.

Figure B-1: WPA Overview
IEEE 802.1x offers an effective framework for authenticating and controlling user traffic to a
protected network, as well as providing a vehicle for dynamically varying data encryption keys via
EAP from a RADIUS server, for example. This framework enables using a central authentication
server, which employs mutual authentication so that a rogue wireless user does not join the
network.
It is important to note that 802.1x does not provide the actual authentication mechanisms. When
using 802.1x, the EAP type, such as Transport Layer Security (EAP-TLS), or EAP Tunneled
Transport Layer Security (EAP-TTLS), defines how the authentication takes place.
Note: For environments with a Remote Authentication Dial-In User Service (RADIUS)
infrastructure, WPA supports Extensible Authentication Protocol (EAP). For environments
without a RADIUS infrastructure, WPA supports the use of a pre-shared key.
Together, these technologies provide a framework for strong user authentication.
Windows XP implements 802.1x natively, and several NETGEAR switch and wireless access
point products support 802.1x.

Temporal Key Integrity Protocol (TKIP)
WPA uses TKIP to provide important data encryption enhancements including a per-packet key
mixing function, a message integrity check (MIC) named Michael, an extended initialization
vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the
following:
•
•
•
The verification of the security configuration after the encryption keys are determined.
The synchronized changing of the unicast encryption key for each frame.
The determination of a unique starting unicast encryption key for each preshared key
authentication.
Michael
With 802.11 and WEP, data integrity is provided by a 32-bit integrity check value (ICV) that is
appended to the 802.11 payload and encrypted with WEP. Although the ICV is encrypted, you can
use cryptanalysis to change bits in the encrypted payload and update the encrypted ICV without
being detected by the receiver.
With WPA, a method known as Michael specifies a new algorithm that calculates an 8-byte
message integrity check (MIC) using the calculation facilities available on existing wireless
devices. The MIC is placed between the data portion of the IEEE 802.11 frame and the 4-byte ICV.
The MIC field is encrypted together with the frame data and the ICV.
Michael also provides replay protection. A new frame counter in the IEEE 802.11 frame is used to
prevent replay attacks.
Optional AES Support to be Phased In
One of the encryption methods supported by WPA, besides TKIP, is the advanced encryption
standard (AES), although AES support will not be required initially for Wi-Fi certification. This is
viewed as the optimal choice for security conscience organizations, but the problem with AES is
that it requires a fundamental redesign of the NIC’s hardware in both the station and the access
point. TKIP is a pragmatic compromise that allows organizations to deploy better security while
AES capable equipment is being designed, manufactured, and incrementally deployed.

Is WPA Perfect?
WPA is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS)
attacks. If the access point receives two data packets that fail the message integrity code (MIC)
within 60 seconds of each other, then the network is under an active attack, and as a result, the
access point employs counter measures, which include disassociating each station using the access
point. This prevents an attacker from gleaning information about the encryption key and alerts
administrators, but it also causes users to lose network connectivity for 60 seconds. More than
anything else, this may just prove that no single security tactic is completely invulnerable. WPA is
a definite step forward in WLAN security over WEP and has to be thought of as a single part of an
end-to-end network security strategy.
Product Support for WPA
Starting in August, 2003, NETGEAR, Inc. wireless Wi-Fi certified products will support the WPA
standard. NETGEAR, Inc. wireless products that had their Wi-Fi certification approved before
August, 2003 will have one year to add WPA so as to maintain their Wi-Fi certification.
WPA requires software changes to the following:
•
•
•
Wireless access points
Wireless network adapters
Wireless client programs
Supporting a Mixture of WPA and WEP Wireless Clients is Discouraged
To support the gradual transition of WEP-based wireless networks to WPA, a wireless AP can
support both WEP and WPA clients at the same time. During the association, the wireless AP
determines which clients use WEP and which clients use WPA. The disadvantage to supporting a
mixture of WEP and WPA clients is that the global encryption key is not dynamic. This is because
WEP-based clients cannot support it. All other benefits to the WPA clients, such as integrity, are
maintained.
However, a mixed mode supporting WPA and non-WPA clients would offer network security that
is no better than that obtained with a non-WPA network, and thus this mode of operation is
discouraged.

Preparing Your PCs for Network Access
This appendix describes how to prepare your PCs to connect to the Internet through the
NETGEAR RangeMax™ Wireless PCI Adapter WPN311.
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 98SE 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.
