ZyXEL G-570S v2 User’s Guide 23CHAPTER 1 Introducing the ZyXEL DeviceThis chapter introduces the main applications and features of the ZyXEL Device. It also introduces the ways you can manage the ZyXEL Device.1.1 OverviewThe ZyXEL Device is a 4-in-1 Access Point with Super G and Turbo G wireless technology. Access Point (AP), repeater, bridge and wireless client functions allow you to use the ZyXEL Device in various network deployments. Super G and Turbo G technology boost the wireless data throughput.The ZyXEL Device Access Point (AP) allows wireless stations to communicate and/or access a wired network. It can work as a bridge and repeater to extend your wireless network. You can also use it as a wireless client to access a wired network through another AP. The ZyXEL Device uses IEEE 802.1x, WEP data encryption, WPA (Wi-Fi Protected Access), WPA2 and MAC address filtering to give mobile users highly secured wireless connectivity. Both IEEE 802.11b and IEEE 802.11g compliant wireless devices can associate with the ZyXEL Device.In addition to being highly flexible, the ZyXEL Device is easy to install and configure.1.2 Applications for the ZyXEL DeviceHere are some application examples of how you can use your ZyXEL Device. 1.2.1 Access Point for Internet AccessThe ZyXEL Device is an ideal access solution for wireless Internet connection. A typical Internet access application for your ZyXEL Device is shown as follows.
Chapter 1 Introducing the ZyXEL DeviceZyXEL G-570S v2 User’s Guide24Figure 1 Internet Access Application1.2.2 Corporate Network Access ApplicationIn situations where users need to access corporate network resources and the Internet, the ZyXEL Device is an ideal solution for wireless stations to connect to the corporate network without expensive network cabling. Stations A, B and C can access the wired network through the ZyXEL Devices.The following figure depicts a typical application of the ZyXEL Device in an enterprise environment. The three computers with wireless adapters are allowed to access the network resource through the ZyXEL Device after account validation by the network authentication server.Figure 2 Corporate Network Application1.2.3 Wireless Client ApplicationThe ZyXEL Device can function as a wireless client to connect to a network via an Access Point (AP). The AP provides access to the wired network and the Internet.
Chapter 1 Introducing the ZyXEL DeviceZyXEL G-570S v2 User’s Guide 25Figure 3 Wireless Client Application 1.2.4 Bridge / RepeaterThe ZyXEL Device can act as a wireless network bridge and establish wireless links with other APs. The ZyXEL Devices in the following example are using bridge mode with a star configuration. A, B, C and D are connected to independent wired networks and have bridge connections at the same time (B, C and D can communicate with A). Figure 4 Bridge ApplicationA ZyXEL Device in bridge mode without an Ethernet connection can function as a repeater. It transmits traffic from one AP to another AP without using a wired connection. C in the following graphic repeats wireless traffic between A and B.
Chapter 1 Introducing the ZyXEL DeviceZyXEL G-570S v2 User’s Guide26Figure 5 Bridge Repeater Application1.2.5 Access Point and RepeaterSet the ZyXEL Device to AP+Repeater mode to have it simultaneously provide access for wireless clients and use the repeater function. This allows you to extend the coverage of your wireless network without installing Ethernet cable to connect the ZyXEL Device. In the following figure, B is in AP+Repeater mode. B functions as an AP for wireless clients C and D. B also repeats traffic between the wireless clients and AP A which is connected to the wired network. You could also set AP A to AP+Repeater mode so that wireless clients could connect to A as well.Figure 6 AP+Repeater Application1.3 Ways to Manage the ZyXEL DeviceUse any of the following methods to manage the ZyXEL Device.• Web Configurator. This is recommended for everyday management of the ZyXEL Device using a (supported) web browser.• Command Line Interface. Line commands are mostly used for troubleshooting by service engineers. • FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
Chapter 1 Introducing the ZyXEL DeviceZyXEL G-570S v2 User’s Guide 271.4 Good Habits for Managing the ZyXEL DeviceDo the following things regularly to make the ZyXEL Device more secure and to manage the ZyXEL Device more effectively.• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the ZyXEL Device. You could simply restore your last configuration.1.5 LEDsFigure 7 LEDsThe following table describes the LEDs on the ZyXEL Device.Table 1 Front Panel LED DescriptionLED COLOR STATUS DESCRIPTIONPWR Green Blinking The ZyXEL Device is not ready or rebooting.On The ZyXEL Device has rebooted successfully and is receiving power.Off The ZyXEL Device is not receiving power.ETHN Green Blinking The ZyXEL Device is sending/receiving data.On The ZyXEL Device has a successful 10Mbps Ethernet connection.Amber Blinking The ZyXEL Device is sending/receiving data.On The ZyXEL Device has a successful 100Mbps Ethernet connection.Off The ZyXEL Device does not have an Ethernet connection.OTIST Green Blinking The OTIST automatic wireless configuration is in progress.On The OTIST feature is activated on the ZyXEL Device.Off The OTIST feature is not activated or activated but the wireless settings have been changed.

ZyXEL G-570S v2 User’s Guide 51CHAPTER 6 System ScreenThis chapter provides information on the System screen.6.1 TCP/IP Parameters6.1.1 IP Address Assignment Every computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses."Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.6.1.2 IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, computers on a LAN share one common network number.Table 9 Private IP Address Ranges10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255
Chapter 6 System ScreenZyXEL G-570S v2 User’s Guide52Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.2, for your device, but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your device will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the device unless you are instructed to do otherwise.6.2 System Settings Click System to open the System Settings screen.Figure 25 System SettingsThe following table describes the labels in this screen.

ZyXEL G-570S v2 User’s Guide 55CHAPTER 7 Wireless ScreensThis chapter discusses how to configure the wireless network settings in your ZyXEL Device. See the appendices for more detailed information about wireless networks. 7.1 Wireless Network OverviewThe following figure provides an example of a wireless network.Figure 26 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and Buse the access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your ZyXEL Device is the AP.Every 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.• If two wireless networks overlap, they should use a different channel.
Chapter 7 Wireless ScreensZyXEL G-570S v2 User’s Guide56Like 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.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.7.2 Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.7.2.1 SSIDNormally, the ZyXEL Device acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the ZyXEL Device does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.This type of security is fairly weak, however, because there are ways for unauthorized wireless devices to get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the wireless network.7.2.2 MAC Address FilterEvery device that can use a wireless network has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless network, see the device’s User’s Guide or other documentation.You can use the MAC address filter to tell the ZyXEL Device which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then, they can use that MAC address to use the wireless network.7.2.3 User AuthenticationAuthentication is the process of verifying whether a wireless device is allowed to use the wireless network. You can make every user log in to the wireless network before they can use it. However, every device in the wireless network has to support IEEE 802.1x to do this.For wireless networks, you can store the user names and passwords for each user in a RADIUS server. This is a server used in businesses more than in homes. If you do not have a RADIUS server, you cannot set up user names and passwords for your users.1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 7 Wireless ScreensZyXEL G-570S v2 User’s Guide 57Unauthorized wireless devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.7.2.4 EncryptionWireless 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.The types of encryption you can choose depend on the type of authentication. (See Section7.2.3 on page 56 for information about this.)For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP,WPA-PSK, or WPA2-PSK.Usually, you should set up the strongest encryption that every device in the wireless network supports. For example, suppose you have a wireless network with the ZyXEL Device and you do not have a RADIUS server. Therefore, there is no authentication. Suppose the wireless network has two devices. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network."It is recommended that wireless networks use WPA-PSK,WPA, or stronger encryption. The other types of encryption are better than none at all, but it is still possible for unauthorized wireless devices to figure out the original information pretty quickly.When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option (WPA compatible) to support WPA as well. In this case, if some of the devices support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA compatible option in the ZyXEL Device.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every device in the wireless network must have the same key.Table 11 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No Security WPAStatic WEPWPA-PSKStrongest WPA2-PSK WPA2
Chapter 7 Wireless ScreensZyXEL G-570S v2 User’s Guide587.2.5 One-Touch Intelligent Security Technology (OTIST)With ZyXEL’s OTIST, you set up the SSID and the encryption (WEP or WPA-PSK) on the ZyXEL Device. Then, the ZyXEL Device transfers them to the devices in the wireless networks. As a result, you do not have to set up the SSID and encryption on every device in the wireless network.The devices in the wireless network have to support OTIST, and they have to be in range of the ZyXEL Device when you activate it. See Section 7.9 on page 81 for more details.7.3 Wireless Performance OverviewThe following sections introduce different ways to improve the performance of the wireless network.7.3.1 Quality of Service (QoS)You can turn on Wi-Fi MultiMedia (WMM) QoS to improve the performance of voice and video applications in the wireless network. QoS gives high priority to voice and video, which makes them run more smoothly. Similarly, it gives low priority to many large file downloads so that they do not reduce the quality of other applications.7.4 Additional Wireless TermsThe following table describes wireless network terms and acronyms used in the ZyXEL Device’s Web Configurator.Table 12 Additional Wireless TermsTERM DESCRIPTIONIntra-BSS Traffic This describes direct communication (not through the ZyXEL Device) between two wireless devices within a wireless network. You might disable this kind of communication to enhance security within your wireless network.RTS/CTS Threshold In a wireless network which covers a large area, wireless devices are sometimes not aware of each other’s presence. This may cause them to send information to the AP at the same time and result in information colliding and not getting through.By setting this value lower than the default value, the wireless devices must sometimes get permission to send information to the ZyXEL Device. The lower the value, the more often the devices must get permission.If this value is greater than the fragmentation threshold value (see below), then wireless devices never have to get permission to send information to the ZyXEL Device.Preamble A preamble affects the timing in your wireless network. There are two preamble modes: long and short. If a device uses a different preamble mode than the ZyXEL Device does, it cannot communicate with the ZyXEL Device.Authentication The process of verifying whether a wireless device is allowed to use the wireless network.Max. Frame Burst Enable this to improve the performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks. Maximum Frame Burst sets the maximum time that the ZyXEL Device transmits IEEE 802.11g wireless traffic only.
Chapter 7 Wireless ScreensZyXEL G-570S v2 User’s Guide 597.5 Quality of ServiceThis section discusses the Quality of Service (QoS) features available on the ZyXEL Device.7.5.1 WMM QoSWMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless networks. It controls WLAN transmission priority on packets to be transmitted over the wireless network.WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.On APs without WMM QoS, all traffic streams are given the same access priority to the wireless network. If the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity, then the new traffic stream reduces the throughput of the other traffic streams.The ZyXEL Device uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag or DSCP information in each packet’s header. The ZyXEL Device automatically determines the priority to use for an individual traffic stream. This prevents reductions in data transmission for applications that are sensitive to latency (delay) and jitter (variations in delay).7.5.1.1 WMM QoS PrioritiesThe following table describes the WMM QoS priority levels that the ZyXEL Device uses.Fragmentation Threshold A small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy.Roaming If you have two or more ZyXEL Devices (or other wireless access points) on your wireless network, you can enable this option so that wireless devices can change locations without having to log in again. This is useful for devices, such as notebooks, that move around a lot.Table 12 Additional Wireless TermsTERM DESCRIPTIONTable 13 WMM QoS PrioritiesPRIORITY LEVEL DESCRIPTIONvoice(WMM_VOICE)Typically used for traffic that is especially sensitive to jitter. Use this priority to reduce latency for improved voice quality.video(WMM_VIDEO)Typically used for traffic which has some tolerance for jitter but needs to be prioritized over other data traffic.best effort(WMM_BEST_EFFORT)Typically used for traffic from applications or devices that lack QoS capabilities. Use best effort priority for traffic that is less sensitive to latency, but is affected by long delays, such as Internet surfing.background(WMM_BACKGROUND)This is typically used for non-critical traffic such as bulk transfers and print jobs that are allowed but that should not affect other applications and users. Use background priority for applications that do not have strict latency and throughput requirements.

Your G-570S v2 supports WDS connections to other G-570S v2 APs.This provides a cost-effective solution for wireless network expansion.OTIST (One-Touch Intelligent Security Technology)OTIST allows your ZyXEL Device to assign its SSID and security settings (WEP or WPA-PSK) to ZyXEL wireless adapters that support OTIST and are within transmission range. The ZyXEL wireless adapters must also have OTIST enabled.Table 31 Feature Specifications (continued)
Appendix A Product SpecificationsZyXEL G-570S v2 User’s Guide 10310/100M Auto-negotiating Ethernet/Fast Ethernet InterfaceThis auto-negotiating feature allows the ZyXEL Device to detect the speed of incoming transmissions and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.Ethernet port connections can be in half-duplex or full-duplex mode. Full-duplex refers to a device's ability to send and receive simultaneously, while half-duplex indicates that traffic can flow in only one direction at a time. The Ethernet port must use the same speed or duplex mode setting as the peer Ethernet port in order to connect.10/100M Auto-crossover Ethernet/Fast Ethernet InterfaceThe LAN interface automatically adjusts to either a crossover or straight-through Ethernet cable. Reset Button The reset button is built into the rear panel. Use this button to restart the device or restore the factory default password. 802.11g Wireless LAN Standard The ZyXEL Device complies with the IEEE 802.11g wireless standard.IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. Wi-Fi Protected Access Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences between WPA and WEP are user authentication and improved data encryption.WPA2 WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.SSL Passthrough The ZyXEL Device allows SSL connections to go through the ZyXEL Device. SSL (Secure Sockets Layer) uses a public key to encrypt data that's transmitted over an SSL connection. Both Netscape Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an SSL connection start with "https" instead of "http". Wireless LAN MAC Address Filtering Your ZyXEL Device checks the MAC address of the wireless station against a list of allowed or denied MAC addresses.WEP Encryption WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network to help keep network communications private.IEEE 802.1x Network Security The ZyXEL Device supports the IEEE 802.1x standard to enhance user authentication. Use an EAP-compatible RADIUS (RFC2138, 2139 - Remote Authentication Dial In User Service) server to authenticate a limitless number of users using EAP (Extensible Authentication Protocol). EAP is an authentication protocol that supports multiple types of authentication.Full Network Management The embedded web configurator is an all-platform web-based utility that allows you to easily access the ZyXEL Device's management settings. Logging and Tracing Built-in message logging and packet tracing.Wireless Association List With the wireless association list, you can see the list of the wireless stations that are currently using the ZyXEL Device to access your wired network.

ZyXEL G-570S v2 User’s Guide 129APPENDIX D 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 91 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 with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide130Figure 92 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. An 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.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide 131Figure 93 Infrastructure WLANChannelA channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than 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 hidden 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.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide132Figure 94 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. "Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.Fragmentation 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.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide 133If 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 802.11b/g compliant wireless adapters support long preamble, but not all support short preamble. Select Long preamble if you are unsure what preamble mode the wireless adapters support, and to provide more reliable communications in busy wireless networks. Select Short preamble if you are sure the wireless adapters support it, and to provide more efficient communications.Select Dynamic to have the AP automatically use short preamble when wireless adapters support it, otherwise the AP uses long preamble."The AP and the wireless adapters MUST use 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 several 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.Table 35 IEEE 802.11gDATA RATE (MBPS) MODULATION1 DBPSK (Differential Binary Phase Shift Keyed)2 DQPSK (Differential Quadrature Phase Shift Keying)5.5 / 11 CCK (Complementary Code Keying) 6/9/12/18/24/36/48/54 OFDM (Orthogonal Frequency Division Multiplexing)
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide134Wireless security methods available on the ZyXEL Device are data encryption, wireless client authentication, restricting access by device MAC address and hiding the ZyXEL Device identity.The following figure shows the relative effectiveness of these wireless security methods available on your ZyXEL Device."You must enable the same wireless security settings on the ZyXEL Device and on all wireless clients that you want to associate with it. IEEE 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.• AuthorizationTable 36 Wireless Security LevelsSECURITY LEVEL SECURITY TYPELeast S e c u r e Most SecureUnique SSID (Default)Unique SSID with Hide SSID EnabledMAC Address FilteringWEP EncryptionIEEE802.1x EAP with RADIUS Server AuthenticationWi-Fi Protected Access (WPA)WPA2
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide 135Determines 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. • 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. .
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide136For 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. However, 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 D Wireless LANsZyXEL G-570S v2 User’s Guide 137Dynamic 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 screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled."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. 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.Table 37 Comparison of EAP Authentication TypesEAP-MD5 EAP-TLS EAP-TTLS PEAP LEAPMutual Authentication No Yes Yes Yes YesCertificate – Client No Yes Optional Optional NoCertificate – Server No Yes Yes Yes NoDynamic Key Exchange No Yes Yes Yes YesCredential Integrity None Strong Strong Strong ModerateDeployment Difficulty Easy Hard Moderate Moderate ModerateClient Identity Protection No No Yes Yes No
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide138EncryptionBoth 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.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 keys. 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.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide 139Wireless 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 the WPA 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 ExampleYou 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.3The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.Figure 95 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 (only) allows it to join the network if the password matches.3The AP and wireless clients use the pre-shared key to generate a common PMK (Pairwise Master Key).
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide1404The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them.Figure 96 WPA(2)-PSK AuthenticationSecurity Parameters SummaryRefer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type. MAC address filters are not dependent on how you configure these security features.Antenna 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.

Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide 141Positioning 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) or 5GHz(IEEE 802.11a) is needed to communicate efficiently in a wireless LAN. Radiation 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.• 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.
Appendix D Wireless LANsZyXEL G-570S v2 User’s Guide142For 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.
