Introduction
This chapter introduces the NETGEAR WAG302 ProSafe Dual Band Wireless Access Point.
Minimal prerequisites for installation are presented in “System Requirements” on page 2-5.
About the WAG302 ProSafe Dual Band Wireless Access
Point
The WAG302 ProSafe Dual Band Wireless Access Point is the basic building block of a wireless
LAN infrastructure. It provides connectivity between Ethernet wired networks and radio-equipped
wireless notebook systems, desktop systems, print servers, and other devices.
The WAG302 provides wireless connectivity to multiple wireless network devices within a fixed
range or area of coverage, interacting with a wireless network interface card (NIC) via an antenna.
T ypically, an individual in-building access point provides a maximum connectivity area with about
a 300 foot radius. The WAG302 ProSafe Dual Band Wireless Access Point can support a small
group of users in a range of several hundred feet. Most access points are rated between 10-30 users
simultaneously.
The WAG302 ProSafe Dual Band Wireless Access Point acts as a bridge between the wired LAN
and wireless clients. Connecting multiple WAG302 Access Points via a wired Ethernet backbone
can further lengthen 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 to another and still maintain seamless connection to the
network.
The auto-sensing capability of the WAG302 ProSafe Dual Band Wireless Access Point allows
packet transmission at up to 108 Mbps, or at reduced speeds to compensate for distance or
electromagnetic interference.

Basic Installation and Configuration
This chapter describes how to set up your WAG302 ProSafe Dual Band Wireless Access Point for
wireless connectivity to your LAN. This basic configuration will enable computers with 802.11b
or 802.11a/g wireless adapters to do such things as connect to the Internet, or access printers and
files on your LAN.
Note: Indoors, computers can connect over 802.11b or 802.11a/g wireless
networks at ranges of several hundred feet or more. This distance can allow for
others outside your area to access your network. It is important to take appropriate steps
to secure your network from unauthorized access. The WAG302 Access Point provides
highly effective security features which are covered in detail in “Understanding WEP/
WPA Security Options” on page 3-18. Deploy the security features appropriate to your
needs.
You need to prepare these three things before you can establish a connection through your wireless
access point:
•A location for the WAG302 that conforms to the Observing Placement and Range Guidelines
below.
•The wireless access point connected to your LAN through a device such as a hub, switch,
router, or Cable/DSL gateway.
•One or more computers with properly configured 802.11b or 802.11a/g wireless adapters.
Observing Placement and Range Guidelines
The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless access point. The latency, data throughput performance, and
notebook power consumption of wireless adapters also vary depending on your configuration
choices.
Basic Installation and Configuration3-1
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the WAG302. For complete
performance specifications, see Appendix A, “Specifications.
For best results, place your wireless access point:
•Near the center of the area in which your PCs will operate.
•In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls).
•Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones.
•Away from large metal surfaces.
•Putting the antenna in a vertical position provides best side-to-side coverage. Putting the
antenna in a horizontal position provides best up-and-down coverage.
•If using multiple access points, it is better if adjacent access points use different
radio frequency
Channels to reduce interference. The recommended Channel spacing between adjacent access
points is 5 Channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Cabling Requirements
The WAG302 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with
RJ-45 connectors.

Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
Understanding WAG302 Wireless Security Options
Your wireless data transmissions can be received well beyond your walls by anyone with a
compatible adapter. For this reason, use the security features of your wireless equipment. The
WAG302 Access Point provides highly effective security features which are covered in detail in
this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
•Restrict Access Based on MAC address. You can restrict access to only trusted PCs so that
unknown PCs cannot wirelessly connect to the WAG302. MAC address filtering adds an
obstacle against unwanted access to your network, but the data broadcast over the wireless link
is fully exposed.
•Turn Off the Broadcast of the Wireless Network Name (SSID). If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network ‘discovery’ feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.
•Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
•Use WPA or WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data
security. The very strong authentication along with dynamic per frame rekeying of WPA make
it virtually impossible to compromise. Because this is a new standard, wireless device driver
and software availability may be limited.
•Use AutoCell Enhanced RF Security ‘Stealth Mode.’ In addition to standard encryption and
security mechanisms such as WEP and WPA, the WAG302 AutoCell feature provides
self-organizing micro cells for an additional level of privacy for enterprises. In this mode,
AutoCell shrinks the size of coverage to the minimum to reach clients but also shrinks the size
of the beacons that access points use to announce their presence. This mode makes an
enterprise wireless LAN nearly invisible to users outside an office building. AutoCell clients
such as the NETGEAR WAG511 are highly-recommended for Enhanced RF Security.
Installing the WAG302 Access Point
Before installing the WAG302 ProSafe Dual Band Wireless Access Point, you should make sure
that your Ethernet network is up and working. You will be connecting the access point to the
Ethernet network so that computers with 802.11b or 802.11a/g wireless adapters will be able to
communicate with computers on the Ethernet network. In order for this to work correctly, verify
that you have met all of the system requirements, shown on page 2-5.
1SETUPTHE WAG302 ACCESS POINT
Tip: Before mounting the WAG302 in a high location, first set up and test the WAG302 to
verify wireless network connectivity.
a.Prepare a computer with an Ethernet adapter. If this computer is already part of your
network, record its TCP/IP configuration settings.
b.Configure the computer with a static IP address of 192.168.0.36 and 255.255.255.0 for the
Subnet Mask.
c.Connect an Ethernet cable from the WAG302 to the computer.
d.Turn on your computer, connect the power adapter to the WAG302 and verify the
following:
–The PWR power light goes on.

AutoCell AP/Client Interaction
AutoCell's self-organizing micro cells provide performance benefits and an additional level of
privacy for enterprises.
•Automatic Transmit Power Control. An AutoCell-enabled client’s RF transmit power level
is automatically coordinated with an AutoCell-enabled AP. This creates client micro-cells and
reduces co-channel interference with other clients and APs on the same frequency and
improves overall throughput and performance. (Requires: AutoCell-enabled AP)
•Automatic Load-Balancing. An AutoCell-enabled client will seek out and associate to the
lightest loaded AutoCell-enabled AP available. (Requires: AutoCell-enabled AP)
•Rapid Roaming. An AutoCell-enabled client will accurately and rapidly detect movement as
distinguished from RF anomalies such as arbitrary and momentary changes in the surrounding
RF domain. When it detects true movement, the client immediately seeks the best available
AP at the highest data rate possible instead of waiting for the data rate to decline. (Does not
Require AutoCell-enabled APs)

•RTS Threshold: Request to Send Threshold. The packet size that is used to determine if it
should use the CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
mechanism or the CSMA/CA mechanism for packet transmission. With the CSMA/CD
transmission mechanism, the transmitting station sends out the actual packet as soon as it has
waited for the silence period. With the CSMA/CA transmission mechanism, the transmitting
station sends out an RTS packet to the receiving station, and waits for the receiving station to
send back a CTS (Clear to Send) packet before sending the actual packet data. The default is
2346.
•Fragmentation Length: 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. The default is 2346.
•Beacon Interval: The Beacon Interval. Specifies the interval time between 20ms and 100 0ms

•Repeater: If selected, this AP will operate as a Repeater only , and send all traffic to the remote
AP. If selected, you must enter the MAC address (physical address) of the remote AP.

Wireless Networking Basics
This chapter provides an overview of Wireless networking.
Wireless Networking Overview
The WAG302 Access Point conforms to the Institute of Electrical and Electronics Engineers
(IEEE) 802.11a, 802.11b, and 802.11g standards for wireless LANs (WLANs).
•IEEE 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM), a new encoding
scheme that offers certain benefits over a spread spectrum in channel availability and data rate.
On an 802.11a wireless link, data is transmitted in the unlicensed radio spectrum at 5GHz. The
802.11a uses OFDM to define a total of 8 non-overlapping 200 MHz channels across the 2
lower bands; each of these is divided into 52 sub carriers and each carrier is approximately 300
KHz wide. The 802.11a wireless link offers a maximum data rate of 54 Mbps, but will
automatically back down to rates 48, 36, 24, 18, 12, 9, and 6 Mbps.
•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 2.5GHz. The
maximum data rate for the 802.11b 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.
Wireless Networking BasicsB-1
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
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.
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 W indows 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.
The ESSID is usually broadcast in the air from an access point. The wireless station sometimes can
be configured with the ESSID ANY. This means the wireless station will try to associate with
whichever access point has the stronger radio frequency (RF) signal, providing that both the access
point and wireless station use Open System authentication.
B-2Wireless Networking Basics
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
Authentication and WEP Data Encryption
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 these two types of authentication methods:
•Open System. With Open System authentication, a wireless computer can join any network
and receive any messages that are not encrypted.
•Shared Key. 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.
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 WAG302:
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.
Wireless Networking BasicsB-3
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
•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 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.

If the decrypted text does not match the original challenge text (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.

Figure B-2: Shared key authentication
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 device decrypts the data using the
same WEP Key. For authentication purposes, the network uses Open System Authentication.
Wireless Networking BasicsB-5
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
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 device decrypts the
data using the same WEP Key . For authentication purposes, the wireless 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.

Table B-1:Encryption Key Sizes
Encryption Key Size# of Hexadecimal DigitsExample of Hexadecimal Key Con t ent
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.
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, and so on.
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
The wireless frequencies used by 802.11a/g networks are discussed below.
802.11b/g Wireless Channels
IEEE 802.11b/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
Wireless Networking BasicsB-7
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
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.
The radio frequency channels used in 802.11b/g networks are listed in Table B-2:
Note: The available cha nnels supported by the wireless products in various countries are dif ferent.
For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are
supported in Europe and Australia.
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.
B-8Wireless Networking Basics
202-10078-01
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302
802.11a Wireless Channels
IEEE 802.11a utilizes 300 MHz of bandwidth in the 5 GHz Unlicensed National Information
Infrastructure (U-NII) band. Though the lower 200 MHz is physically contiguous, the FCC has
divided the total 300 MHz into three distinct domains, each with a different legal maximum power
output.
The WAG302 user can use thirteen channels in non-turbo mode.
Table B-3:802.11a Turbo Mode Off Radio Frequency Channels (Turbo Mode OFF)
The available channels supported by the wireless products in various countries are different.
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.
The IEEE introduced the WEP as an optional security measure to secure 802.11b (W i-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 802.1 1 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.
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 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 authentica tes wireless
users before they gain access to the network.
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).
