Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG3021-4 About This Manual202-10078-01
Introduction 2-1202-10078-01Chapter 2IntroductionThis 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 PointThe 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. Typically, 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG3022-2 Introduction202-10078-01Key FeaturesThe WAG302 Access Point is easy-to-use and provides solid wireless and networking support.Supported Standards and ConventionsThe following standards and conventions are supported:•Standards Compliant. The Wireless Access Point complies with the IEEE 802.11a/g for Wireless LANs.•WEP support. Support for WEP is included. 64-bit, 128-bit, and 152-bit keys are supported.•DHCP Client Support. DHCP provides a dynamic IP address to PCs and other devices upon request. The WAG302 can act as a client and obtain information from your DHPC server.•SNMP Support. Support for Simple Network Management Protocol (SNMP) Management Information Base (MIB) management.Key FeaturesThe NETGEAR WAG302 provides solid functionality, including these features:•AutoCell RF Management. AutoCell provides advanced automated RF management that improves performance and enhances security.• Multiple Operating Modes – Wireless Access Point. Operates as a standard 802.11a/g.– Point-to-Point Bridge. In this mode, the WAG302 only communicates with another bridge-mode wireless station. You must enter the MAC address (physical address) of the other bridge-mode wireless station in the field provided. WEP should be used to protect this communication. – Point-to-Multi-Point Bridge. Select this only if this WAG302 is the “Master” for a group of bridge-mode wireless stations. The other bridge-mode wireless stations must be set to Point-to-Point Bridge mode, using this WAG302's MAC address. They then send all traffic to this “Master”, rather than communicate directly with each other. WEP should be used to protect this traffic. – Wireless Repeater. In this half-duplex mode, the WAG302 only communicates with another repeater-mode wireless station. You must enter the MAC address of both adjacent repeater-mode wireless stations in the fields provided. WEP should be used to protect this communication. •Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded easily, using only your Web browser, and can be upgraded remotely.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Introduction 2-3202-10078-01•Access Control. The Access Control MAC address filtering feature can ensure that only trusted wireless stations can use the WAG302 to gain access to your LAN.•Simple Configuration. If the default settings are unsuitable, they are easy to change.•Hidden Mode. The SSID is not broadcast, assuring only clients configured with the correct SSID can connect.•Secure Telnet Command Line Interface. The Telnet command line interface enables direct access over the serial port and easy scripting of configuration of multiple WAG302 across an extensive network via the Ethernet interface. An SSH client is required.•Configuration Backup. Configuration settings can be backed up to a file and restored.•Secure and Economical Operation.

Power can be supplied to the WAG302 over the Ethernet port from any 802.3af compliant mid-span or end-span source such as the NETGEAR FSM7326P Managed Power over Ethernet Layer 3 managed switch.•Autosensing Ethernet Connection with Auto Uplink Interface. Connects to 10/100 Mbps IEEE 802.3 Ethernet networks.•LED Indicators. Power, test, LAN speed, LAN activity, and wireless activity are easily identified.AutoCell—The Self-Organizing Wireless NetworkAutoCellTM, an embedded control system for 802.11 WLANs. AutoCell increases available bandwidth and reduces WLAN installation and operating costs significantly. AutoCell is completely automatic: It is a continuous communication system that relies on a lightweight protocol to monitor changes on the wireless domain while keeping overhead very low. Among AutoCell's inherent advantages:• Elimination of manual site surveys and channel maps• Dynamic load balancing• Plug-and-play-implementation• Transparent fault recovery and failoverSince AutoCell is completely self-organizing, it holds human intervention to a minimum. That reduces the people costs associated with deployment, management, and maintenance—making 802.11 WLANs practical, efficient, and cost-effective.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG3022-4 Introduction202-10078-01802.11a/g Standards-based Wireless NetworkingThe WAG302 ProSafe Dual Band Wireless Access Point provides a bridge between Ethernet wired LANs and 802.11a/g compatible wireless LAN networks. It provides connectivity between Ethernet wired networks and radio-equipped wireless notebook systems, desktop systems, print servers, and other devices. Additionally, the WAG302 supports the following wireless features:• Distributed coordinated function (CSMA/CA, Back off procedure, ACK procedure, retransmission of unacknowledged frames)• RTS/CTS handshake• Beacon generation• Packet fragmentation and reassembly• Short or long preamble• Roaming among access points on the same subnetAutosensing Ethernet Connections with Auto Uplink The WAG302 can connect to a standard Ethernet network. The LAN interface is autosensing and capable of full-duplex or half-duplex operation. The wireless access point incorporates Auto UplinkTM technology. The Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a computer or an ‘uplink’ connection such as to a switch or hub. That port will then configure itself to the correct configuration. This feature also eliminates any concerns about crossover cables, as Auto Uplink will accommodate either type of cable to make the right connection.Compatible and Related NETGEAR ProductsFor a list of compatible products from other manufacturers, see the Wireless Ethernet Compatibility Alliance Web site (WECA, see http://www.wi-fi.net).

Basic Installation and Configuration 3-1202-10078-01Chapter 3 Basic Installation and ConfigurationThis 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.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 GuidelinesThe operating distance or range of your wireless connection can vary significantly based 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.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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG3023-2 Basic Installation and Configuration202-10078-01For 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 RequirementsThe WAG302 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with RJ-45 connectors.Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the WAG302.

Deploy the security features appropriate to your needs.Figure 3-1: WAG302 wireless data security optionsThere 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. .O3ECURITY%ASYBUTNOSECURITY-!#!CCESS,IST.ODATASECURITY7%03ECURITYBUTVULNERABLE70!OR70!03+6ERYSTRONGSECURITY!UTO#ELL2&@STEALTHMODE:LUHOHVV'DWD6HFXULW\2SWLRQV5DQJH8SWR)RRW5DGLXV072 ,!.B 0RO3AFE7IRELESS!CCESS0OINT -/$%, -%7IRELESS,!.WAG302
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Basic Installation and Configuration 3-5202-10078-01•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 PointBefore installing the WAG302 ProSafe Dual Band Wireless Access Point, you should make sure that your Ethernet network is up and working.

Wireless Networking Basics B-1202-10078-01Appendix BWireless Networking BasicsThis chapter provides an overview of Wireless networking.Wireless Networking OverviewThe 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 ModeWith 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-2 Wireless Networking Basics202-10078-01In 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 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.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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-3202-10078-01Authentication and WEP Data EncryptionThe 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 AuthenticationThe 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-4 Wireless Networking Basics202-10078-01• 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 AuthenticationThe 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.Figure B-1: Open system authenticationShared Key AuthenticationThe 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.

The station connects to the network.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.This process is illustrated below.Figure B-2: Shared key authenticationOverview of WEP ParametersBefore 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.INTERNET LOCALACT12345678LNKLNK/ACT100Cable/DSL ProSafeWirelessVPN Security FirewallMODEL FVM318PWR TESTWLANEnableAccess Point1) Authenticationrequest sent to AP2) AP sends challenge text3) Client encryptschallenge text andsends it back to AP4) AP decrypts, and if correct,authenticates client5) Client connects to network802.11b AuthenticationShared Key StepsCable orDLS modemClientattemptingto connect
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-6 Wireless Networking Basics202-10078-013. 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 SizeThe 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-7202-10078-01Note: 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 OptionsThe 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 ChannelsThe wireless frequencies used by 802.11a/g networks are discussed below.802.11b/g Wireless ChannelsIEEE 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.

Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-8 Wireless Networking Basics202-10078-01channels 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 more than 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 channels supported by the wireless products in various countries are different. 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.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.Table B-2: 802.11b/g Radio Frequency ChannelsChannel Frequency 1 2412 MHz 2 2417 MHz 3 2422 MHz 4 2427 MHz 5 2432 MHz 6 2437 MHz 7 2442 MHz 8 2447 MHz 9 2452 MHz 10 2457 MHz 11 2462 MHz 12 2467 MHz 13 2472 MHz

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 Table B-4: 802.11a Turbo Mode Off Radio Frequency Channels (Turbo Mode ON)Channel Frequency42 5.21 GHz50 5.25 GHz58 5.29 GHz152 5.76 GHz160 5.8 GHz
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-11202-10078-01The 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.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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-12 Wireless Networking Basics202-10078-01How 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 discouragedThese 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.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).
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-13202-10078-01The 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-14 Wireless Networking Basics202-10078-01WPA Authentication: Enterprise-level User Authentication via 802.1x/EAP and RADIUSFigure B-3: WPA OverviewIEEE 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.

Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-15202-10078-01Figure B-4: 802.1x Authentication SequenceThe AP sends Beacon Frames with WPA information element to the stations in the service set. Information elements include the required authentication method (802.1x or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES). Probe Responses (AP to station) and Association Requests (station to AP) also contain WPA information elements.1. Initial 802.1x communications begin with an unauthenticated supplicant (client device) attempting to connect with an authenticator (802.11 access point). The client sends an EAP-start message. This begins a series of message exchanges to authenticate the client. 2. The access point replies with an EAP-request identity message. 1234567Client with a WPA- enabled wireless adapter and supplicant (Win XP, Funk, Meetinghouse) For example, a WPA-enabled AP For example, a RADIUS server
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-16 Wireless Networking Basics202-10078-013. The client sends an EAP-response packet containing the identity to the authentication server. The access point responds by enabling a port for passing only EAP packets from the client to an authentication server located on the wired side of the access point. The access point blocks all other traffic, such as HTTP, DHCP, and POP3 packets, until the access point can verify the client's identity using an authentication server (for example, RADIUS). 4. The authentication server uses a specific authentication algorithm to verify the client's identity. This could be through the use of digital certificates or some other EAP authentication type. 5. The authentication server will either send an accept or reject message to the access point. 6. The access point sends an EAP-success packet (or reject packet) to the client. 7. If the authentication server accepts the client, then the access point will transition the client's port to an authorized state and forward additional traffic. The important part to know at this point is that the software supporting the specific EAP type resides on the authentication server and within the operating system or application “supplicant” software on the client devices. The access point acts as a “pass through” for 802.1x messages, which means that you can specify any EAP type without needing to upgrade an 802.1x-compliant access point. As a result, you can update the EAP authentication type to such devices as token cards (Smart Cards), Kerberos, one-time passwords, certificates, and public key authentication, or as newer types become available and your requirements for security change. WPA Data Encryption Key ManagementWith 802.1x, the rekeying of unicast encryption keys is optional. Additionally, 802.11 and 802.1x provide no mechanism to change the global encryption key used for multicast and broadcast traffic. With WPA, rekeying of both unicast and global encryption keys is required. For the unicast encryption key, the Temporal Key Integrity Protocol (TKIP) changes the key for every frame, and the change is synchronized between the wireless client and the wireless access point (AP). For the global encryption key, WPA includes a facility (the Information Element) for the wireless AP to advertise the changed key to the connected wireless clients.If configured to implement dynamic key exchange, the 802.1x authentication server can return session keys to the access point along with the accept message. The access point uses the session keys to build, sign and encrypt an EAP key message that is sent to the client immediately after sending the success message. The client can then use contents of the key message to define applicable encryption keys. In typical 802.1x implementations, the client can automatically change encryption keys as often as necessary to minimize the possibility of eavesdroppers having enough time to crack the key in current use.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Wireless Networking Basics B-17202-10078-01Temporal 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.MichaelWith 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 InOne 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.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302B-18 Wireless Networking Basics202-10078-01Is 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 WPAStarting 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 programsSupporting a Mixture of WPA and WEP Wireless Clients is DiscouragedTo 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.

Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302-2 Glossary202-10078-01ARPAddress Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called a DLC address), such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address. There is also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host's IP address.Auto UplinkAuto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs. straight-through Ethernet cables. Auto UplinkTM will accommodate either type of cable to make the right connection.CAA Certificate Authority is a trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs. Cat 5Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA). This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum cable length for both 10 and 100 Mbits/second networks.Certificate AuthorityA Certificate Authority is a trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs. The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact, who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution, such as a credit card company, which provides it with information to confirm an individual's claimed identity. CAs are a critical component in data security and electronic commerce because they guarantee that the two parties exchanging information are really who they claim to be.DHCPAn Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients.

Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302Glossary -3202-10078-01DNSShort for Domain Name System (or Service), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. Domain NameA descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.DSLShort for digital subscriber line, but is commonly used in reference to the asymmetric version of this technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world gain access. Dynamic Host Configuration ProtocolDHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients.

EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a user requests connection to a WLAN through an AP, which then requests the identity of the user and transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of identity, which the AP gets from the user and then sends back to the server to complete the authentication. EAP is defined by RFC 2284.ESSIDThe Extended Service Set Identification (ESSID) is a thirty-two character (maximum) alphanumeric key identifying the wireless local area network. GatewayA local device, usually a router, that connects hosts on a local network to other networks.

When using a one-way hash function, one can compare a calculated message digest against the message digest that is decrypted with a public key to verify that the message hasn't been tampered with. This comparison is called a "hashcheck." MDI/MDIXIn cable wiring, the concept of transmit and receive are from the perspective of the PC, which is wired as a Media Dependant Interface (MDI). In MDI wiring, a PC transmits on pins 1 and 2. At the hub, switch, router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is referred to as Media Dependant Interface - Crossover (MDI-X). See also Auto Uplink.

An application programming interface (API) for sharing services and information on local-area networks (LANs). Provides for communication between stations of a network where each station is given a name. These names are alphanumeric names, 16 characters in length. netmaskCombined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router. A number that explains which part of an IP address comprises the network address and which part is the host address on that network. It can be expressed in dotted-decimal notation or as a number appended to the IP address. For example, a 28-bit mask starting from the MSB can be shown as 255.255.255.192 or as /28 appended to the IP address.Network Address TranslationA technique by which several hosts share a single IP address for access to the Internet.packetA block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum.Point-to-Point ProtocolPPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet.RADIUSShort for Remote Authentication Dial-In User Service, RADIUS is an authentication system. Using RADIUS, you must enter your user name and password before gaining access to a network. This information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access. Though not an official standard, the RADIUS specification is maintained by a working group of the IETF. RIPA protocol in which routers periodically exchange information with one another so that they can determine minimum distance paths between sources and destinations.routerA device that forwards data between networks. An IP router forwards data based on IP source and destination addresses.
Reference Manual for the NETGEAR ProSafe Dual Band Wireless Access Point WAG302-6 Glossary202-10078-01SSIDA Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID.Subnet MaskCombined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router. TLSShort for Transport Layer Security, TLS is a protocol that guarantees privacy and data integrity between client/server applications communicating over the Internet. The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of an encryption algorithm and cryptographic keys before data is transmitted or received. Based on Netscape’s SSL 3.0, TLS supercedes and is an extension of SSL. TLS and SSL are not interoperable.UTPUnshielded twisted pair is the cable used by 10BASE-T and 100BASE-Tx Ethernet networks.WANA long distance link used to extend or connect remotely located local area networks.
