Chapter 1 Getting StartedNWD310N User’s Guide 231.2 Application OverviewThis section describes some network applications for the NWD310N. You can either set the network type to Infrastructure and connect to an AP or use Ad-Hoc mode and connect to a peer computer (another wireless device in Ad-Hoc mode).1.2.1 Infrastructure To connect to a network via an access point (AP), set the NWD310N network type to Infrastructure (see Chapter 4 on page 56). Through the AP, you can access the Internet or the wired network behind the AP. Figure 2 Application: Infrastructure 1.2.2 Ad-Hoc To set up a small independent wireless workgroup without an AP, use Ad-Hoc (see Chapter 4 on page 56).Ad-Hoc does not require an AP or a wired network. Two or more wireless clients communicate directly with each other."Wi-Fi Protected Setup (WPS) is not available in ad-hoc mode.
Chapter 1 Getting StartedNWD310N User’s Guide24Figure 3 Application: Ad-Hoc 1.3 Hardware and Utility InstallationFollow the instructions in the Quick Start Guide to install the ZyXEL utility and make hardware connections.1.3.1 ZyXEL Utility IconAfter you install and start the ZyXEL utility, an icon for the ZyXEL utility appears in the system tray."The ZyXEL utility system tray icon displays only when the NWD310N is installed properly."When you use the ZyXEL utility, it automatically disables Wireless Zero Configuration (WZC) in Windows XP.Figure 4 ZyXEL Utility: System Tray Icon
Chapter 1 Getting StartedNWD310N User’s Guide 25The color of the ZyXEL utility system tray icon indicates the status of the NWD310N. Refer to the following table for details. 1.4 Configuration Methods To configure your NWD310N, use one of the following applications:• Wireless Zero Configuration (WZC, the Windows XP wireless configuration tool) or WLAN AutoConfig (the Windows Vista wireless configuration tool).• The ZyXEL utility. "Do NOT use Windows XP’s Wireless Zero Configuration tool at the same time you use the ZyXEL utility.1.4.1 Enabling Windows Wireless Configuration "When you use the ZyXEL utility, it automatically disables Windows XP’s wireless configuration tool. If you want to use the Windows XP wireless configuration tool to configure the NWD310N, you need to disable the ZyXEL utility. Right-click the utility icon ( ) in the system tray and select Exit. Figure 5 Enable WZCRefer to the appendices for information on how to use the Windows wireless configuration tool to manage the NWD310N.To reactivate the ZyXEL utility, double-click the ( ) icon on your desktop or click Start, (All) Programs, ZyXEL Wireless N PCI Adapter Utility, ZyXEL Wireless N PCI Adapter Utility.Table 3 ZyXEL Utility: System Tray Icon COLOR DESCRIPTIONRed The NWD310N is not connected to a wireless network.Green The NWD310N is connected to a wireless network.

The ZyXEL utility screens are similar in all Microsoft Windows versions. Screens for Windows XP are shown in this User’s Guide. "Click the icon (located in the top right corner) to display the online help window.
NWD310N User’s Guide 27CHAPTER 2 TutorialThe following sections show you how to join a wireless network using the ZyXEL utility, as in the following diagram. The wireless client is labeled C and the access point is labeled AP. Figure 6 Infrastructure Network2.1 Connecting to an AP using Wi-Fi Protected Setup (WPS)This section gives you an example of how to set up your wireless network using WPS. This example uses the NWD310N as the wireless client, and ZyXEL’s NBG334W as the Access Point (AP). "The Access Point must be a WPS-aware device.There are two WPS methods for creating a secure connection. This tutorial shows you both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 2.1.1 on page 27.This is the easier method.•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NWD310N’s interface. See Section 2.1.2 on page 29. This is the more secure method, since one device can authenticate the other.2.1.1 Push Button Configuration (PBC)1Make sure that your access point is turned on and that it is within range of the computer with the NWD310N installed. 2Make sure that you have installed the NWD310N’s driver and utility on your computer.
Chapter 2 TutorialNWD310N User’s Guide283In the NWD310N’s utility, click the Adapter tab, enable WPS and select PBC (Push Button Configuration). In the screen that appears, click Start. 4Log into the AP’s web configurator and locate its WPS settings section. On the NBG334W, press the Push Button button in the Network > Wireless Client > WPS Station screen. "It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The AP sends the proper configuration settings to the NWD310N. This may take up to two minutes. Then the NWD310N is able to communicate with the AP securely. The following figure shows you an example to set up wireless network and security by pressing a button on both the AP (the NBG334W in this example) and the NWD310N.
Chapter 2 TutorialNWD310N User’s Guide 29Figure 7 Example WPS Process: PBC Method2.1.2 PIN ConfigurationWhen you use the PIN configuration method, you need to use both the NWD310N’s utility and the AP’s configuration interface.1In the NWD310N’s Adaptor tab, select WPS and PIN - Use this Device’s PIN. Note down the PIN in the screen that appears. 2Enter the PIN number in the AP’s configuration interface. In the NBG334W, use the PIN field in the Network > Wireless LAN > WPS Station screen. 3Click the Start buttons on both the NWD310N utility screen and the AP’s configuration utility (the WPS Station screen on the NBG334W) within two minutes. The NWD310N authenticates the wireless client and sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NWD310N securely. NWD310N APSECURITY INFOCOMMUNICATIONWITHIN 2 MINUTES

Chapter 2 TutorialNWD310N User’s Guide322.2 Connecting to an AP Without Using WPSThere are three ways to connect the wireless client (the NWD310N) to a network without using WPS.• Configure nothing and leave the wireless client to automatically scan for and connect to any available network that has no wireless security configured.• Manually connect to a network (see Section 2.2.1 on page 32).• Configure a profile to have the wireless client automatically connect to a specific network or peer computer (see Section 2.2.2 on page 34). 2.2.1 Manually Connecting to a Wireless LAN This example illustrates how to manually connect your wireless client to an access point (AP) configured for WPA-PSK security and connected to the Internet. Before you connect to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this example, the AP’s SSID is “SSID_Example3” and its pre-shared key is “ThisismyWPA-PSKpre-sharedkey”. After you install the ZyXEL utility and then insert the wireless client, follow the steps below to connect to a network using the Site Survey screen. 1Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.Figure 9 ZyXEL Utility: Site Survey2The wireless client automatically searches for available wireless networks. Click Scan if you want to search again. If no entry displays in the Available Network List, that means there is no wireless network available within range. Make sure the AP or peer computer is turned on, or move the wireless client closer to the AP or peer computer. See Table 4.3 on page 49 for detailed field descriptions.3To connect to an AP or peer computer, either click an entry in the list and then click Connect or double-click an entry (SSID_Example3 in this example). 4When you try to connect to an AP with security configured, a window will pop up prompting you to specify the security settings. Enter the pre-shared key and leave the encryption type at the default setting.Use the Next button to move on to the next screen. You can use the Back button at any time to return to the previous screen, or the Exit button to return to the Site Survey screen.

You can also configure different profiles for different networks, for example if you connect a notebook computer to wireless networks at home and at work.This example illustrates how to set up a profile and connect the wireless client to an access point configured for WPA-PSK security. In this example, the AP’s SSID is “SSID_Example3” and its pre-shared key is “ThisismyWPA-PSKpre-sharedkey”. You have chosen the profile name “PN_Example3”.1Open the ZyXEL utility and click the Profile tab to open the screen as shown. Click Add to configure a new profile.Figure 13 ZyXEL Utility: Profile2The Add New Profile screen appears. The wireless client automatically searches for available wireless networks, which are displayed in the Scan Info box. You can also configure your profile for a wireless network that is not in the list.

NWD310N User’s Guide 37CHAPTER 3 Wireless LANsThis chapter provides background information on wireless Local Area Networks.3.1 Wireless LAN Overview The following figure provides an example of a wireless network with an AP. See Figure 3 on page 24 for an Ad Hoc network example.Figure 19 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the InternetEvery wireless network must follow these basic guidelines.• Every device in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.• If two wireless networks overlap, they should use a different channel.
Chapter 3 Wireless LANsNWD310N User’s Guide38Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.• Every device in the same wireless network must use security compatible with the AP or peer computer.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.3.2 Wireless LAN Security Wireless LAN security is vital to your network to protect wireless communications.If you do not enable any wireless security on your NWD310N, the NWD310N’s wireless communications are accessible to any wireless networking device that is in the coverage area. "You can use only WEP encryption if you set the NWD310N to Ad-hoc mode.See the appendices for more detailed information about wireless security.3.2.1 User Authentication and EncryptionYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.3.2.1.1 WEP3.2.1.1.1 Data Encryption WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the NWD310N and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.There are two ways to create WEP keys in your NWD310N.• Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN.For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s).• Enter the WEP keys manually.
Chapter 3 Wireless LANsNWD310N User’s Guide 39Your NWD310N allows you to configure up to four 64-bit, 128-bit or 152-bit WEP keys. Only one key is used as the default key at any one time.3.2.1.1.2 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto, Open and Shared.• Open mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.• Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer.• Auto authentication mode allows the NWD310N to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations.3.2.1.2 IEEE 802.1x The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.3.2.1.2.1 EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. The NWD310N supports EAP-TLS, EAP-TTLS (at the time of writing, TTLS is not available in Windows Vista) and EAP-PEAP. Refer to Appendix B on page 103 for descriptions.For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). Certificates (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.3.2.1.3 WPA and WPA2 Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication.Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
Chapter 3 Wireless LANsNWD310N User’s Guide40If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.3.3 WiFi Protected SetupYour NWD310N supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the WiFi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.3.3.1 Push Button ConfigurationWPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and allowing them to connect automatically. You do not need to enter any information. Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their configuration utilities instead of or in addition to the physical button.Take the following steps to set up WPS using the button.1Ensure that the two devices you want to set up are within wireless range of one another. 2Look for a WPS button on each device. If the device does not have one, log into its configuration utility and locate the button (see the device’s User’s Guide for how to do this - for the NWD310N, see Section 4.5.1 on page 62).3Press the button on one of the devices (it doesn’t matter which).4Within two minutes, press the button on the other device. The registrar sends the network name (SSID) and security key through an secure connection to the enrollee.If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s configuration utility. If you see the wireless client in the list, WPS was successful.
Chapter 3 Wireless LANsNWD310N User’s Guide 413.3.2 PIN ConfigurationEach WPS-enabled device has its own PIN (Personal Identification Number). This may either be static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by clicking on a button in the configuration interface). Use the PIN method instead of the push-button configuration (PBC) method if you want to ensure that the connection is established between the devices you specify, not just the first two devices to activate WPS in range of each other. However, you need to log into the configuration interfaces of both devices to use the PIN method.When you use the PIN method, you must enter the PIN from one device (usually the wireless client) into the second device (usually the Access Point or wireless router). Then, when WPS is activated on the first device, it presents its PIN to the second device. If the PIN matches, one device sends the network and security information to the other, allowing it to join the network.Take the following steps to set up a WPS connection between an access point or wireless router (referred to here as the AP) and a client device using the PIN method.1Ensure WPS is enabled on both devices.2Access the WPS section of the AP’s configuration interface. See the device’s User’s Guide for how to do this. 3Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the NWD310N, see Section 4.5 on page 61).4Enter the client’s PIN in the AP’s configuration interface."If the client device’s configuration interface has an area for entering another device’s PIN, you can either enter the client’s PIN in the AP, or enter the AP’s PIN in the client - it does not matter which. 5Start WPS on both devices within two minutes. "Use the configuration utility to activate WPS, not the push-button on the device itself.6On a computer connected to the wireless client, try to connect to the Internet. If you can connect, WPS was successful.If you cannot connect, check the list of associated wireless clients in the AP’s configuration utility. If you see the wireless client in the list, WPS was successful.The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method.
Chapter 3 Wireless LANsNWD310N User’s Guide42Figure 20 Example WPS Process: PIN Method3.3.3 How WPS WorksWhen two WPS-enabled devices connect, each device must assume a specific role. One device acts as the registrar (the device that supplies network and security settings) and the other device acts as the enrollee (the device that receives network and security settings. The registrar creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK or WPA2-PSK is used depends on the standards supported by the devices. If the registrar is already part of a network, it sends the existing information. If not, it generates the SSID and WPA(2)-PSK randomly.The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point.ENROLLEESECURE EAP TUNNELSSIDWPA(2)-PSKWITHIN 2 MINUTESCOMMUNICATIONThis device’s WPSEnter WPS PIN WPSfrom other device: WPS PIN: 123456WPSSTARTWPSSTARTREGISTRAR
Chapter 3 Wireless LANsNWD310N User’s Guide 43Figure 21 How WPS worksThe roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The next time you use WPS, a different device can be the registrar if necessary.The WPS connection process is like a handshake; only two devices participate in each WPS transaction. If you want to add more devices you should repeat the process with one of the existing networked devices and the new device.Note that the access point (AP) is not always the registrar, and the wireless client is not always the enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients.By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network and can act as either enrollee or registrar (if it supports both functions). If the registrar is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a WPS-enabled device has connected to another device using WPS, it becomes “configured”. A configured wireless client can still act as enrollee or registrar in subsequent WPS connections, but a configured access point can no longer act as enrollee. It will be the registrar in all subsequent WPS connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset it to its factory defaults.3.3.3.1 Example WPS Network SetupThis section shows how security settings are distributed in an example WPS setup.The following figure shows an example network. In step 1, both AP1 and Client 1 are unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security information to set up the network, since it is unconfigured and has no existing information.SECURE TUNNELSECURITY INFOWITHIN 2 MINUTESCOMMUNICATIONACTIVATEWPSACTIVATEWPSWPS HANDSHAKEREGISTRARENROLLEE
Chapter 3 Wireless LANsNWD310N User’s Guide44Figure 22 WPS: Example Network Step 1In step 2, you add another wireless client to the network. You know that Client 1 supports registrar mode, but it is better to use AP1 for the WPS handshake with the new client since you must connect to the access point anyway in order to use the network. In this case, AP1 must be the registrar, since it is configured (it already has security information for the network). AP1 supplies the existing security information to Client 2.Figure 23 WPS: Example Network Step 2In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead.REGISTRARENROLLEESECURITY INFOCLIENT 1 AP1REGISTRARCLIENT 1 AP1ENROLLEECLIENT 2EXISTING CONNECTIONSECURITY INFO
Chapter 3 Wireless LANsNWD310N User’s Guide 45Figure 24 WPS: Example Network Step 33.3.4 Limitations of WPSWPS has some limitations of which you should be aware. • WPS works in Infrastructure networks only (where an AP and a wireless client communicate). It does not work in Ad-Hoc networks (where there is no AP).• When you use WPS, it works between two devices only. You cannot enroll multiple devices simultaneously, you must enroll one after the other. For instance, if you have two enrollees and one registrar you must set up the first enrollee (by pressing the WPS button on the registrar and the first enrollee, for example), then check that it successfully enrolled, then set up the second device in the same way.• WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to a network you already set up using WPS. WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2-PSK pre-shared key from the registrar device to the enrollee devices (see Section 4.3.1.2 on page 52 for information on pre-shared keys). Whether the network uses WPA-PSK or WPA2-PSK depends on the device. You can check the configuration interface of the registrar device to discover the key the network is using (if the device supports this feature). Then, you can enter the key into the non-WPS device and join the network as normal (the non-WPS device must also support WPA-PSK or WPA2-PSK).• When you use the PBC method, there is a short period (from the moment you press the button on one device to the moment you press the button on the other device) when any WPS-enabled device could join the network. This is because the registrar has no way of identifying the “correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a possible way for a hacker to gain access to a network.CLIENT 1 AP1REGISTRARCLIENT 2EXISTING CONNECTIONSECURITY INFOENROLLEEAP1EXISTING CONNECTION
Chapter 3 Wireless LANsNWD310N User’s Guide46You can easily check to see if this has happened. WPS works between only two devices simultaneously, so if another device has enrolled your device will be unable to enroll, and will not have access to the network. If this happens, open the access point’s configuration interface and look at the list of associated clients (usually displayed by MAC address). It does not matter if the access point is the WPS registrar, the enrollee, or was not involved in the WPS handshake; a rogue device must still associate with the access point to gain access to the network. Check the MAC addresses of your wireless clients (usually printed on a label on the bottom of the device). If there is an unknown MAC address you can remove it or reset the AP.

NWD310N User’s Guide 81APPENDIX A Setting up Your Computer’s IPAddress"The purpose of this appendix is to show you how to configure an IP address on your computer depending on what operating system you have. It does NOT mean that your NWD310N supports all these operating systems. To see what operating systems your NWD310N supports, refer to Chapter 7 on page 77.All computers must have a 10M or 100M Ethernet adapter card and TCP/IP installed. Windows 95/98/Me/NT/2000/XP/Vista, Macintosh OS 7 and later operating systems and all versions of UNIX/LINUX include the software components you need to install and use TCP/IP on your computer. Windows 3.1 requires the purchase of a third-party TCP/IP application package.TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems.After the appropriate TCP/IP components are installed, configure the TCP/IP settings in order to "communicate" with your network. If you manually assign IP information instead of using dynamic assignment, make sure that your computers have IP addresses that place them in the same subnet as the NWD310N’s LAN port.Windows 95/98/MeClick Start, Settings, Control Panel and double-click the Network icon to open the Network window.
