See Section 2.3.2 on page 30 for details.•Configure your NWD2205 as an Access Point (AP), allowing other devices to connect to it and share its network connections. See Section 2.4 on page 33 for details.2.1.2 What You Need to KnowThe following term may help as you read through this section.WPSWi-Fi Protected Setup (WPS) is a security protocol that lets two or more devices connect securely to one another with a minimum amount of hassle on your part. It most cases, establishing a secure connection with another WPS device is as easy as pushing a button.
Chapter 2TutorialNWD2205 User’s Guide242.1.3 Before You Begin•Make sure that you have already familiarized yourself with the NWD2205’s features and hardware, as described in Chapter 1 on page 17.•You should have valid login information for an existing network Access Point, otherwise you may not be able to make a network connection right away.2.2 Connecting to an AP using Wi-Fi Protected Setup (WPS)This section gives you an example of how to set up your wireless network using WPS. This example uses the NWD2205 as the wireless client, and ZyXEL’s NBG334W as the Access Point (AP). Note: The Access Point must be a WPS-aware device.There are two WPS methods for creating a secure connection. This tutorial shows you both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 2.2.1 on page 24.This is the easier method.•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NWD2205’s interface. See Section 2.2.2 on page 25. This is the more secure method, since one device can authenticate the other.2.2.1 Push Button Configuration (PBC)1Make sure that your access point is turned on and that it is within range of the computer with the NWD2205 installed. 2Make sure that you have installed the NWD2205’s driver and utility on your computer.3In the NWD2205’s utility, click the Adapter tab, enable WPS and select PBC(Push Button Configuration).

A RADIUS (Remote Authentication Dial-In User Service) is a kind of server that manages logins and logout, among other things, for the network to which it is connected.ClientWhen two or more devices are connected digitally to form a network, the one that contacts and obtains data from a server is known as the “client”. Each client is designed to work with one or more specific kinds of servers, and each server requires a specific kind of client. Wireless adapters are clients that connect to a network server through an AP.AuthenticationAuthentication is the process of confirming a client’s or user’s digital identity when they connect to a network. Turning off authentication means disabling all security protocols and opening your network to anyone with the means to connect to it.
Chapter 3Wireless LANsNWD2205 User’s Guide38EncryptionThe process of taking data and encoding it, usually using a mathematical formula, so that it becomes unreadable unless decrypted with the proper code or pass phrase.3.1.3 Before You Begin•You should have valid login information for an existing network Access Point, otherwise you may not be able to make a network connection right away.3.2 Wireless LAN Overview The following figure provides an example of a wireless network with an AP. SeeFigure 3 on page 20 for an Ad Hoc network example.Figure 22 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the InternetEvery wireless network must follow these basic guidelines.•Every device in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.
Chapter 3Wireless LANsNWD2205 User’s Guide 39•If two wireless networks overlap, they should use a different channel.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.•Every device in the same wireless network must use security compatible with the AP or peer computer.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.3.3 Wireless LAN Security Wireless LAN security is vital to your network to protect wireless communications.If you do not enable any wireless security on your NWD2205, the NWD2205’s wireless communications are accessible to any wireless networking device that is in the coverage area. Note: You can use only WEP encryption if you set the NWD2205 to Ad-hoc mode.See the appendices for more detailed information about wireless security.3.3.1 User Authentication and EncryptionYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.3.3.1.1 WEP3.3.1.1.1 Data Encryption WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the NWD2205 and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.There are two ways to create WEP keys in your NWD2205.
Chapter 3Wireless LANsNWD2205 User’s Guide40•Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN.For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s).•Enter the WEP keys manually.Your NWD2205 allows you to configure up to four 64-bit or 128-bit WEP keys. Only one key is used as the default key at any one time.3.3.1.1.2 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto,Open and Shared.•Open mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.•Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer.•Auto authentication mode allows the NWD2205 to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations.3.3.1.2 IEEE 802.1x The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.3.3.1.2.1 EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. The NWD2205 supports EAP-TLS, EAP-TTLS (at the time of writing, TTLS is not available in Windows Vista) and EAP-PEAP. Refer to Appendix B on page 131 for descriptions.
Chapter 3Wireless LANsNWD2205 User’s Guide 41For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). Certificates (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.3.3.1.3 WPA and WPA2 Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication.Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.3.4 WiFi Protected SetupYour NWD2205 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the WiFi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure).
Chapter 3Wireless LANsNWD2205 User’s Guide42Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.3.4.1 Push Button ConfigurationWPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and allowing them to connect automatically. You do not need to enter any information. Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their configuration utilities instead of or in addition to the physical button.Take the following steps to set up WPS using the button.1Ensure that the two devices you want to set up are within wireless range of one another. 2Look for a WPS button on each device. If the device does not have one, log into its configuration utility and locate the button (see the device’s User’s Guide for how to do this - for the NWD2205, see Section 4.6.1 on page 69).3Press the button on one of the devices (it doesn’t matter which).4Within two minutes, press the button on the other device. The registrar sends the network name (SSID) and security key through an secure connection to the enrollee.If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s configuration utility. If you see the wireless client in the list, WPS was successful.3.4.2 PIN ConfigurationEach WPS-enabled device has its own PIN (Personal Identification Number). This may either be static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by clicking on a button in the configuration interface). Use the PIN method instead of the push-button configuration (PBC) method if you want to ensure that the connection is established between the devices you specify, not just the first two devices to activate WPS in range of each other. However, you
Chapter 3Wireless LANsNWD2205 User’s Guide 43need to log into the configuration interfaces of both devices to use the PIN method.When you use the PIN method, you must enter the PIN from one device (usually the wireless client) into the second device (usually the Access Point or wireless router). Then, when WPS is activated on the first device, it presents its PIN to the second device. If the PIN matches, one device sends the network and security information to the other, allowing it to join the network.Take the following steps to set up a WPS connection between an access point or wireless router (referred to here as the AP) and a client device using the PIN method.1Ensure WPS is enabled on both devices.2Access the WPS section of the AP’s configuration interface. See the device’s User’s Guide for how to do this. 3Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the NWD2205, see Section 4.6 on page 68).4Enter the client’s PIN in the AP’s configuration interface.Note: If the client device’s configuration interface has an area for entering another device’s PIN, you can either enter the client’s PIN in the AP, or enter the AP’s PIN in the client - it does not matter which. 5Start WPS on both devices within two minutes. Note: Use the configuration utility to activate WPS, not the push-button on the device itself.6On a computer connected to the wireless client, try to connect to the Internet. If you can connect, WPS was successful.If you cannot connect, check the list of associated wireless clients in the AP’s configuration utility. If you see the wireless client in the list, WPS was successful.
Chapter 3Wireless LANsNWD2205 User’s Guide44The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method.Figure 23 Example WPS Process: PIN Method3.4.3 How WPS WorksWhen two WPS-enabled devices connect, each device must assume a specific role. One device acts as the registrar (the device that supplies network and security settings) and the other device acts as the enrollee (the device that receives network and security settings. The registrar creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK or WPA2-PSK is used depends on the standards supported by the devices.

Chapter 3Wireless LANsNWD2205 User’s Guide 45already part of a network, it sends the existing information. If not, it generates the SSID and WPA(2)-PSK randomly.The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point.Figure 24 How WPS worksThe roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The next time you use WPS, a different device can be the registrar if necessary.The WPS connection process is like a handshake; only two devices participate in each WPS transaction. If you want to add more devices you should repeat the process with one of the existing networked devices and the new device.Note that the access point (AP) is not always the registrar, and the wireless client is not always the enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients.By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network and can act as either enrollee or registrar (if it supports both functions). If the registrar is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a WPS-enabled device has connected to another device using WPS, it becomes “configured”. A configured wireless client can still act as enrollee or registrar in subsequent WPS connections, but a configured access point can no longer act as enrollee. It will be the registrar in all SECURE TUNNELSECURITY INFOWITHIN 2 MINUTESCOMMUNICATIONACTIVATEWPSACTIVATEWPSWPS HANDSHAKEREGISTRARENROLLEE
Chapter 3Wireless LANsNWD2205 User’s Guide46subsequent WPS connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset it to its factory defaults.3.4.3.1 Example WPS Network SetupThis section shows how security settings are distributed in an example WPS setup.The following figure shows an example network. In step 1, both AP1 and Client 1are unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security information to set up the network, since it is unconfigured and has no existing information.Figure 25 WPS: Example Network Step 1In step 2, you add another wireless client to the network. You know that Client 1supports registrar mode, but it is better to use AP1 for the WPS handshake with the new client since you must connect to the access point anyway in order to use the network. In this case, AP1 must be the registrar, since it is configured (it already has security information for the network). AP1 supplies the existing security information to Client 2.Figure 26 WPS: Example Network Step 2REGISTRARENROLLEESECURITY INFOCLIENT 1 AP1REGISTRARCLIENT 1 AP1ENROLLEECLIENT 2EXISTING CONNECTION
Chapter 3Wireless LANsNWD2205 User’s Guide 47In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead.Figure 27 WPS: Example Network Step 33.4.4 Limitations of WPSWPS has some limitations of which you should be aware. •WPS works in Infrastructure networks only (where an AP and a wireless client communicate). It does not work in Ad-Hoc networks (where there is no AP).•When you use WPS, it works between two devices only. You cannot enroll multiple devices simultaneously, you must enroll one after the other. For instance, if you have two enrollees and one registrar you must set up the first enrollee (by pressing the WPS button on the registrar and the first enrollee, for example), then check that it successfully enrolled, then set up the second device in the same way.•WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to a network you already set up using WPS. WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2-PSK pre-shared key from the registrar device to the enrollee devices (see Section 4.4.1.3 on page 57 for information on pre-shared keys). Whether the network uses WPA-PSK or WPA2-PSK depends on the device. You can check the CLIENT 1 AP1REGISTRARCLIENT 2EXISTING CONNECTIONENROLLEEAP1
Chapter 3Wireless LANsNWD2205 User’s Guide48configuration interface of the registrar device to discover the key the network is using (if the device supports this feature). Then, you can enter the key into the non-WPS device and join the network as normal (the non-WPS device must also support WPA-PSK or WPA2-PSK).•When you use the PBC method, there is a short period (from the moment you press the button on one device to the moment you press the button on the other device) when any WPS-enabled device could join the network. This is because the registrar has no way of identifying the “correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a possible way for a hacker to gain access to a network.You can easily check to see if this has happened. WPS works between only two devices simultaneously, so if another device has enrolled your device will be unable to enroll, and will not have access to the network. If this happens, open the access point’s configuration interface and look at the list of associated clients (usually displayed by MAC address). It does not matter if the access point is the WPS registrar, the enrollee, or was not involved in the WPS handshake; a rogue device must still associate with the access point to gain access to the network. Check the MAC addresses of your wireless clients (usually printed on a label on the bottom of the device). If there is an unknown MAC address you can remove it or reset the AP.

See Section 4.5 on page 62 for details.•On the Adapter screen, you can configure the NWD2205 hardware, such as activating WPS mode or its power saving feature. See Section 4.6 on page 68for details.4.1.2 What You Need to KnowThe following terms and concepts may help as you read through this section.Wired Equivalent Privacy (WEP)WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and wireless networks to keep the transmission private. Although one of the original wireless encryption protocols, WEP is also the weakest. Many people use it strictly to deter unintentional usage of their wireless network by outsiders.Wi-fi Protected Access (WPA)Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. It improves data encryption by using Temporal Key Integrity Protocol (TKIP),
Chapter 4Station ModeNWD2205 User’s Guide50Message Integrity Check (MIC) and IEEE 802.1x. WPA uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. The WPA protocol affords users with vastly stronger security than the WEP protocol. It comes in two different varieties: WPA and WPA2. Always try to use WPA2 as it implements the full version of the security standard while WPA does not.Pre-Shared Key (PSK)A pre-shared key is a password shared between the server and the client that unlocks the algorithm used to encrypt the data traffic between them. Without the proper password, the client and the server cannot communicate.Extensible Authentication Protocol (EAP)An enhanced security framework designed to improve an existing security protocol, such as WPA-PSK or WPA2-PSK.4.1.3 Before You Begin•Make sure the ZyXEL utility is already installed.

NWD2205 User’s Guide 131APPENDIX B Wireless LANsWireless LAN TopologiesThis section discusses ad-hoc and infrastructure wireless LAN topologies.Ad-hoc Wireless LAN ConfigurationThe simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an ad-hoc wireless LAN. Figure 108 Peer-to-Peer Communication in an Ad-hoc NetworkBSSA Basic Service Set (BSS) exists when all communications between wireless clients or between a wireless client and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A and B can access the wired network and communicate
Appendix BWireless LANsNWD2205 User’s Guide132with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other.Figure 109 Basic Service SetESSAn Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS).This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood.
Appendix BWireless LANsNWD2205 User’s Guide 133An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate.Figure 110 Infrastructure WLANChannelA channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.RTS/CTSA hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a
Appendix BWireless LANsNWD2205 User’s Guide134hidden node. Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 111 RTS/CTSWhen station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked.When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission.Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.
Appendix BWireless LANsNWD2205 User’s Guide 135Fragmentation ThresholdAFragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames.A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.Preamble TypePreamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet.Short preamble increases performance as less time sending preamble means more time for sending data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short preamble. Use long preamble if you are unsure what preamble mode other wireless devices on the network support, and to provide more reliable communications in busy wireless networks. Use short preamble if you are sure all wireless devices on the network support it, and to provide more efficient communications.Use the dynamic setting to automatically use short preamble when all wireless devices on the network support it, otherwise the NWD2205 uses long preamble.Note: The wireless devices MUSTuse the same preamble mode in order to communicate.IEEE 802.11g Wireless LANIEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has
Appendix BWireless LANsNWD2205 User’s Guide136several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:Wireless Security OverviewWireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network.Wireless security methods available on the NWD2205 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NWD2205 identity.The following figure shows the relative effectiveness of these wireless security methods available on your NWD2205.Note: You must enable the same wireless security settings on the NWD2205 and on all wireless clients that you want to associate with it.

Appendix BWireless LANsNWD2205 User’s Guide 137IEEE 802.1xIn June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:•User based identification that allows for roaming.•Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. •Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless clients. RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:•Authentication Determines the identity of the users.•AuthorizationDetermines the network services available to authenticated users once they are connected to the network.•AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server. Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:•Access-RequestSent by an access point requesting authentication.•Access-RejectSent by a RADIUS server rejecting access.•Access-AcceptSent by a RADIUS server allowing access.
Appendix BWireless LANsNWD2205 User’s Guide138•Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:•Accounting-RequestSent by the access point requesting accounting.•Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of EAP Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all authentication types. EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. .For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.EAP-MD5 (Message-Digest Algorithm 5)MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client. The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text.
Appendix BWireless LANsNWD2205 User’s Guide 139However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. EAP-TLS (Transport Layer Security)With EAP-TLS, digital certifications are needed by both the server and the wireless clients for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP)Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.LEAPLEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x.
Appendix BWireless LANsNWD2205 User’s Guide140Dynamic WEP Key ExchangeThe AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen. You may still configure and store keys, but they will not be used while dynamic WEP is enabled.Note: EAP-MD5 cannot be used with Dynamic WEP Key ExchangeFor added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.WPA and WPA2Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA or WPA2 and WEP are improved data encryption and user authentication.If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN.

Appendix BWireless LANsNWD2205 User’s Guide 141If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.EncryptionWPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA2 also uses TKIP when required for compatibility reasons, but offers stronger encryption than TKIP with Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP).TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. They both include 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.WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically.The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network. The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption
Appendix BWireless LANsNWD2205 User’s Guide142keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP)User Authentication WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-authentication. These two features are optional and may not be supported in all wireless devices.Key caching allows a wireless client to store the PMK it derived through a successful authentication with an AP. The wireless client uses the PMK when it tries to connect to the same AP and does not need to go with the authentication process again.Pre-authentication enables fast roaming by allowing the wireless client (already connecting to an AP) to perform IEEE 802.1x authentication with another AP before connecting to it.Wireless Client WPA SupplicantsA wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is theWPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it. WPA(2) with RADIUS Application ExampleTo set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.1The AP passes the wireless client's authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client.
Appendix BWireless LANsNWD2205 User’s Guide 1434The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.Figure 112 WPA(2) with RADIUS Application ExampleWPA(2)-PSK Application ExampleA WPA(2)-PSK application looks as follows.1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols).2The AP checks each wireless client's password and allows it to join the network only if the password matches.3The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID.
Appendix BWireless LANsNWD2205 User’s Guide1444The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them.Figure 113 WPA(2)-PSK AuthenticationSecurity Parameters SummaryRefer to this table to see what other security parameters you should configure for each authentication method or key management protocol type.

Appendix BWireless LANsNWD2205 User’s Guide 145Antenna OverviewAn antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna CharacteristicsFrequencyAn antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.11a) is needed to communicate efficiently in a wireless LANRadiation PatternA radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area. Antenna GainAntenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width. Higher antenna gain improves the range of the signal for better communications. For an indoor site, each 1 dB increase in antenna gain results in a range increase of approximately 2.5%. For an unobstructed outdoor site, each 1dB increase in gain results in a range increase of approximately 5%. Actual results may vary depending on the network environment. Antenna gain is sometimes specified in dBi, which is how much the antenna increases the signal power compared to using an isotropic antenna. An isotropic antenna is a theoretical perfect antenna that sends out radio signals equally well in all directions. dBi represents the true gain that the antenna provides. Types of Antennas for WLANThere are two types of antennas used for wireless LAN applications.
Appendix BWireless LANsNWD2205 User’s Guide146•Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points. •Directional antennas concentrate the RF signal in a beam, like a flashlight does with the light from its bulb. The angle of the beam determines the width of the coverage pattern. Angles typically range from 20 degrees (very directional) to 120 degrees (less directional). Directional antennas are ideal for hallways and outdoor point-to-point applications.Positioning AntennasIn general, antennas should be mounted as high as practically possible and free of obstructions. In point-to–point application, position both antennas at the same height and in a direct line of sight to each other to attain the best performance. For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single AP application, place omni-directional antennas as close to the center of the coverage area as possible. For directional antennas, point the antenna in the direction of the desired coverage area.
