Wizards Introducing the ZyXEL Device (23) Introducing the Web Configurator (31) Wizards (35) 21 22 CHAPTER Introducing the ZyXEL Device This chapter introduces the main applications and features of the ZyXEL Device. It also introduces the ways you can manage the ZyXEL Device. 1.1 Overview The 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 Device Here are some application examples of how you can use your ZyXEL Device. 1.2.1 Access Point for Internet Access The ZyXEL Device is an ideal access solution for wireless Internet connection. A typical Internet access application for your ZyXEL Device is shown as follows. ZyXEL G-570S v2 User’s Guide 23 Chapter 1 Introducing the ZyXEL Device Figure 1 Internet Access Application 1.2.2 Corporate Network Access Application In 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 Application 1.2.3 Wireless Client Application The 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. 24 ZyXEL G-570S v2 User’s Guide Chapter 1 Introducing the ZyXEL Device Figure 3 Wireless Client Application 1.2.4 Bridge / Repeater The 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 Application A 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. ZyXEL G-570S v2 User’s Guide 25 Chapter 1 Introducing the ZyXEL Device Figure 5 Bridge Repeater Application 1.2.5 Access Point and Repeater Set 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 Application 1.3 Ways to Manage the ZyXEL Device Use 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. 26 ZyXEL G-570S v2 User’s Guide Chapter 1 Introducing the ZyXEL Device 1.4 Good Habits for Managing the ZyXEL Device Do 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 LEDs Figure 7 LEDs The following table describes the LEDs on the ZyXEL Device.

ZyXEL G-570S v2 User’s Guide CHAPTER System Screen This chapter provides information on the System screen. 6.1 TCP/IP Parameters 6.1.1 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. Table 9 Private IP Address Ranges 10.0.0.0 10.255.255.255 172.16.0.0 172.31.255.255 192.168.0.0 192.168.255.255 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 Mask Similar to the way houses on a street share a common street name, computers on a LAN share one common network number. ZyXEL G-570S v2 User’s Guide 51 Chapter 6 System Screen Where 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 Settings The following table describes the labels in this screen. Table 10 System Settings LABEL DESCRIPTION Device Name This name can be up to 30 printable characters long.

Leave this field as 0.0.0.0 if you do not know it. Apply Click Apply to save your changes back to the device. Reset Click Reset to reload the previous configuration for this screen. ZyXEL G-570S v2 User’s Guide 53 Chapter 6 System Screen 54 ZyXEL G-570S v2 User’s Guide CHAPTER Wireless Screens This 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 Overview The following figure provides an example of a wireless network. Figure 26 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B use 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. ZyXEL G-570S v2 User’s Guide 55 Chapter 7 Wireless Screens 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. 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 Overview The following sections introduce different types of wireless security you can set up in the wireless network. 7.2.1 SSID Normally, 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 Filter Every 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 Authentication Authentication 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. 56 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. ZyXEL G-570S v2 User’s Guide Chapter 7 Wireless Screens Unauthorized 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 Encryption 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. The types of encryption you can choose depend on the type of authentication. (See Section 7.2.3 on page 56 for information about this.) Table 11 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION RADIUS SERVER No Security WPA Static WEP WPA-PSK Strongest WPA2-PSK WPA2 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, WPAPSK, 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. ZyXEL G-570S v2 User’s Guide 57 Chapter 7 Wireless Screens 7.2.5 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 Overview The 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 Terms The following table describes wireless network terms and acronyms used in the ZyXEL Device’s Web Configurator. Table 12 Additional Wireless Terms 58 TERM DESCRIPTION Intra-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. ZyXEL G-570S v2 User’s Guide Chapter 7 Wireless Screens Table 12 Additional Wireless Terms TERM DESCRIPTION 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. 7.5 Quality of Service This section discusses the Quality of Service (QoS) features available on the ZyXEL Device. 7.5.1 WMM QoS WMM (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 Priorities The following table describes the WMM QoS priority levels that the ZyXEL Device uses. Table 13 WMM QoS Priorities PRIORITY LEVEL DESCRIPTION voice (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.

ZyXEL G-570S v2 User’s Guide Chapter 7 Wireless Screens 7.9 OTIST In a wireless network, the wireless clients must have the same SSID and security settings as the access point (AP) or wireless router (we will refer to both as “AP” here) in order to associate with it. Traditionally this meant that you had to configure the settings on the AP and then manually configure the exact same settings on each wireless client. OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP’s SSID and WEP or WPA-PSK security settings to wireless clients that support OTIST and are within transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if you didn’t configure one manually. OTIST replaces the pre-configured wireless settings on the wireless clients. OTIST is not available in AP+Repeater or Bridge mode at the time of writing. 7.9.1 Enabling OTIST You must enable OTIST on both the AP and wireless client before you start transferring settings. The AP and wireless client(s) MUST use the same Setup key. 7.9.1.1 ZyXEL Device in AP Mode You can enable OTIST using the OTIST button or the web configurator. 7.9.1.1.1 OTIST Button If you use the OTIST button, the default (01234567) or previous saved (through the web configurator) Setup key is used to encrypt the settings that you want to transfer. Hold in the OTIST button for one or two seconds. 7.9.1.1.2 Web Configurator Click Wireless > OTIST in AP, AP+Repeater or Bridge mode to configure and enable OTIST. The screen appears as shown.

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. ZyXEL G-570S v2 User’s Guide Appendix A Product Specifications Table 31 Feature Specifications (continued) 10/100M Autonegotiating Ethernet/ Fast Ethernet Interface This 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. Fullduplex 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 Autocrossover Ethernet/Fast Ethernet Interface The LAN interface automatically adjusts to either a crossover or straightthrough 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. When the ZyXEL Device is in client mode, the wireless association list displays a list of wireless devices and networks in the area. ZyXEL G-570S v2 User’s Guide 103 Appendix A Product Specifications Table 31 Feature Specifications (continued) Output Power Management Output Power Management is the ability to set the level of output power. There may be interference or difficulty with channel assignment when there is a high density of APs within a coverage area. In this case you can lower the output power of each access point, thus enabling you to place access points closer together. Limit the Number of Client Connections You may set a maximum number of wireless stations that may connect to the ZyXEL Device. This may be necessary if for example, there is interference or difficulty with channel assignment due to a high density of APs within a coverage area.
