ZyXEL NWA-1100 User’s Guide 25CHAPTER 1 Introducing the ZyXEL DeviceThis chapter introduces the main applications and features of the ZyXEL Device. It also discusses the ways you can manage your ZyXEL Device.1.1 Introducing the ZyXEL Device Your ZyXEL Device extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. It controls network access with MAC address filtering and RADIUS server authentication.It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access (WPA), WPA2 and WEP data encryption. Its Quality of Service (QoS) features allow you to prioritize time-sensitive or highly important applications such as VoIP.Your ZyXEL Device is easy to install, configure and use. The embedded Web-based configurator enables simple, straightforward management and maintenance.See the Quick Start Guide for instructions on how to make hardware connections.1.2 Applications for the ZyXEL DeviceThe ZyXEL Device can be configured to use the following WLAN operating modes1AP (Access Point)2Wireless Client3Bridge4AP + BridgeApplications for each operating mode are shown below.1.2.1 Access Point 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. Stations A, B and C can access the wired network through the ZyXEL Devices.
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide26Figure 1 Access Point Application1.2.2 Wireless ClientThe ZyXEL Device can be used as a wireless client to communicate with an existing network. In the figure below, the printer can receive requests from the wired computer clients A and B via the ZyXEL Device in Wireless Client mode.Figure 2 Wireless Client ApplicationAP1AP2ABCBSS2BSS1AB
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide 271.2.3 BridgeThe ZyXEL Device can act as a wireless network bridge and establish wireless links with other APs. In the figure below, the ZyXEL Devices (A, B and Z) are connected to independent wired networks and have a bridge connection (A can communicate with B and Z) at the same time. Security between bridged APs (the Wireless Distribution System or WDS) is independent of the security between the wired networks and their respective APs. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared key. See Section 6.4.3 on page 68 for more details. Once the security settings of peer sides match one another, the connection between devices is made.At the time of writing, WDS security is compatible with other ZyXEL NWA-series access points only. Refer to your other access point’s documentation for details. Figure 3 Bridge ApplicationIn the example below, when both ZyXEL Devices are in Bridge mode, they form a WDS (Wireless Distribution System) allowing the computers in LAN 1 to connect to the computers in LAN 2.
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide28Figure 4 Bridging ExampleBe careful to avoid bridge loops when you enable bridging in the ZyXEL Device. Bridge loops cause broadcast traffic to circle the network endlessly, resulting in possible throughput degradation and disruption of communications. The following examples show two network topologies that can lead to this problem: • If two or more ZyXEL Devices (in bridge mode) are connected to the same hub.Figure 5 Bridge Loop: Two Bridges Connected to Hub• If your ZyXEL Device (in bridge mode) is connected to a wired LAN while communicating with another wireless bridge that is also connected to the same wired LAN.
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide 29Figure 6 Bridge Loop: Bridge Connected to Wired LANTo prevent bridge loops, ensure that you enable STP in the Wireless screen or your ZyXEL Device is not set to bridge mode while connected to both wired and wireless segments of the same LAN.1.2.4 AP + BridgeIn AP+Bridge mode, the ZyXEL Device supports both AP and bridge connection at the same time.Using AP + Bridge mode, your ZyXEL Device can extend the range of the WLAN. In the figure below, A and B act as AP + Bridge devices that forward traffic between associated wireless workstations and the wired LAN.When the ZyXEL Device is in AP+Bridge mode, security between APs (the Wireless Distribution System or WDS) is independent of the security between the wireless stations and the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre-shared key. See Section 6.4.4 on page 70 for more details.Unless specified, the term “security settings” refers to the traffic between the wireless stations and the ZyXEL Device.
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide30Figure 7 AP + Bridge Application 1.3 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.• CLI (Command Line Interface). Line commands are mostly used for troubleshooting by service engineers.• FTP (File Transfer Protocol) for firmware upgrades.• SNMP (Simple Network Management Protocol). The device can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.1.4 Configuring Your ZyXEL Device’s Security FeaturesYour ZyXEL Device comes with a variety of security features. This section summarizes these features and provides links to sections in the User’s Guide to configure security settings on your ZyXEL Device. Follow the suggestions below to improve security on your ZyXEL Device and network. 1.4.1 Control Access to Your DeviceEnsure only people with permission can access your ZyXEL Device.• Control physical access by locating devices in secure areas, such as locked rooms. Most ZyXEL Devices have a reset button. If an unauthorized person has access to the reset button, they can then reset the device’s password to its default password, log in and reconfigure its settings.
Chapter 1 Introducing the ZyXEL DeviceZyXEL NWA-1100 User’s Guide 31• Change any default passwords on the ZyXEL Device, such as the password used for accessing the ZyXEL Device’s web configurator (if it has a web configurator). Use a password with a combination of letters and numbers and change your password regularly. Write down the password and put it in a safe place.• Avoid setting a long timeout period before the ZyXEL Device’s web configurator automatically times out. A short timeout reduces the risk of unauthorized person accessing the web configurator while it is left idle. • See Chapter 5 on page 53 for instructions on changing your password and setting the timeout period.• Configure remote management to control who can manage your ZyXEL Device. See Chapter 11 on page 101 for more information. If you enable remote management, ensure you have enabled remote management only on the IP addresses, services or interfaces you intended and that other remote management settings are disabled.1.4.2 Wireless Security Wireless devices are especially vulnerable to attack. If your ZyXEL Device has a wireless function, take the following measures to improve wireless security.• Enable wireless security on your ZyXEL Device. Choose the most secure encryption method that all devices on your network support. See Section 7.4 on page 77 for directions on configuring encryption. If you have a RADIUS server, enable IEEE 802.1x or WPA(2) user identification on your network so users must log in. This method is more common in business environments. • Hide your wireless network name (SSID). The SSID can be regularly broadcast and unauthorized users may use this information to access your network. See Section 6.4 on page 63 for directions on using the web configurator to hide the SSID. • Enable the MAC filter to allow only trusted users to access your wireless network or deny unwanted users access based on their MAC address. See Section 9.4 on page 94 for directions on configuring the MAC filter. 1.5 Good Habits for Managing the ZyXEL DeviceDo the following things regularly to make the ZyXEL Device more secure and to manage it more effectively.• Change the password often. 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 won’t have to totally re-configure the ZyXEL Device; you can simply restore your last configuration.

Chapter 5 System ScreensZyXEL NWA-1100 User’s Guide545.3 What You Need To Know About the System ScreensIP 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.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.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.Table 4 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 5 System ScreensZyXEL NWA-1100 User’s Guide585.6 Technical ReferenceThis section provides some technical information about the topics covered in this chapter.5.6.1 Pre-defined NTP Time Servers ListWhen you turn on the ZyXEL Device for the first time, the date and time start at 2000-01-01 00:00:00. When you select Auto in the System > Time Setting screen, the ZyXEL Device then attempts to synchronize with one of the following pre-defined list of NTP time servers.The ZyXEL Device continues to use the following pre-defined list of NTP time servers if you do not specify a time server or it cannot synchronize with the time server you specified. Start Date Configure the day and time when Daylight Saving Time starts if you selected Enable Daylight Saving. The at field uses the 24 hour format. Here are a couple of examples:Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Second, Sunday, March and 2:00.Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March. The time you type in the at field depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).End Date Configure the day and time when Daylight Saving Time ends if you selected Enable Daylight Saving. The o'clock field uses the 24 hour format. Here are a couple of examples:Daylight Saving Time ends in the United States on the first Sunday of November.

ZyXEL NWA-1100 User’s Guide 61CHAPTER 6 Wireless Settings Screen6.1 OverviewThis chapter discusses the steps to configure the Wireless Settings screen on the ZyXEL Device. It also introduces the wireless LAN (WLAN) and some basic scenarios.Figure 26 Wireless ModeIn the figure above, the ZyXEL Device allows access to another bridge device (A) and a notebook computer (B) upon verifying their settings and credentials. It denies access to other devices (C and D) with configurations that do not match those specified in your ZyXEL Device.6.2 What You Can Do in the Wireless Settings ScreenUse the Wireless > Wireless Settings screen (see Section 6.4 on page 63) to configure the ZyXEL Device to operate in AP (Access Point), Wireless Client, Bridge or AP + Bridge.
Chapter 6 Wireless Settings ScreenZyXEL NWA-1100 User’s Guide626.3 What You Need To Know About Wireless Settings ScreenBSSA 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. ESSAn 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).Operating ModeThe ZyXEL Device can run in four operating modes as follows:•AP (Access Point). The ZyXEL Device is wireless access point that allows wireless communication to other devices in the network.•Wireless Client. The ZyXEL Device acts as a wireless client to access a wireless network.•Bridge. The ZyXEL Device acts as a wireless network bridge and establishes wireless links with other APs. You need to know the MAC address of the peer device, which also must be in bridge mode. The ZyXEL Device can establish up to five wireless links with other APs.•AP+Bridge Mode. The ZyXEL Device functions as a bridge and access point simultaneously. Refer to Chapter 1 on page 25 for illustrations of these wireless applications.SSIDThe SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same 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.ChannelA 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.
Chapter 6 Wireless Settings ScreenZyXEL NWA-1100 User’s Guide 63Wireless ModeThe 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. Your ZyXEL Device can support 802.11b Only, 802.11g Only and 802.11b+g.6.4 Wireless Settings ScreenUse this screen to choose the operating mode for your ZyXEL Device. Click Wireless > Wireless Settings. The screen varies depending upon the operating mode you select.6.4.1 Access Point ModeUse this screen to use your ZyXEL Device as an access point. Select AP as the Operation Mode. The following screen displays.Figure 27 Wireless: Access Point
Chapter 6 Wireless Settings ScreenZyXEL NWA-1100 User’s Guide64The following table describes the general wireless LAN labels in this screen.Table 9 Wireless: Access PointLABEL DESCRIPTIONBasic SettingsOperation Mode Select AP from the drop-down list. SSID The SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same SSID. Select an SSID Profile from the drop-down list box.Note: If you are configuring the ZyXEL Device from a computer connected to the wireless LAN and you change the ZyXEL Device’s SSID or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the ZyXEL Device’s new settings.Hide SSID If you hide the SSID, then the ZyXEL Device cannot be seen when a wireless client scans for local APs. The trade-off for the extra security of “hiding” the ZyXEL Device may be inconvenience for some valid WLAN clients.Channel Set the operating frequency/channel depending on your particular region. To manually set the ZyXEL Device to use a channel, select a channel from the drop-down list box. Click MAINTENANCE and then the Channel Usage tab to open the Channel Usage screen to make sure the channel is not already used by another AP or independent peer-to-peer wireless network. To have the ZyXEL Device automatically select a channel, click Scan instead. Wireless Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate with the ZyXEL Device.Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate with the ZyXEL Device.Select 802.11b+g to allow both IEEE802.11b and IEEE802.11g compliant WLAN devices to associate with the ZyXEL Device. The transmission rate of your ZyXEL Device might be reduced.Advanced SettingsBeacon Interval When a wirelessly networked device sends a beacon, it includes with it a beaconinterval. This specifies the time period before the device sends the beacon again.The interval tells receiving devices on the network how long they can wait in lowpower mode before waking up to handle the beacon. This value can be set from20ms to 1000ms. A high value helps save current consumption of the access point.Intra-BSS TrafficWhen Intra-BSS is enabled, wireless client can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless client can still access the wired network but cannot communicate with each other.DTIM Interval Delivery Traffic Indication Message (DTIM) is the time period after which broadcastand multicast packets are transmitted to mobile clients in the Power Saving mode. A high DTIM value can cause clients to lose connectivity withthe network. This value can be set from 1 to 100.WMM Select this to turn on WMM QoS (Wireless MultiMedia Quality of Service). The ZyXEL Device assigns priority to packets based on the IEEE 802.1q or DSCP information in their headers. If a packet has no WMM information in its header, it is assigned the default priority.
