ZyXEL NWD-170N User’s Guide 24 Chapter 1 Getting Started
ZyXEL NWD-170N User’s Guide CHAPTER 2 Tutorial The following sections show you how to join a wireless network using the ZyXEL utility, as in the following diagrams. The wireless client is labeled C and the access point is labeled AP. Figure 6 Infrastructure Network There are three ways to connect the wireless client (the NWD-170N) to a network. • Configure nothing and leave the wireless client to automatically scan for and connect to any available network that has no wireless security configured.
ZyXEL NWD-170N User’s Guide Figure 7 ZyXEL Utility: Site Survey 2 The 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 37 for detailed field descriptions.
ZyXEL NWD-170N User’s Guide Figure 9 ZyXEL Utility: Confirm Save 6 The ZyXEL utility returns to the Link Info screen while it connects to the wireless network using your settings. When the wireless link is established, the ZyXEL utility icon in the system tray turns green and the Link Info screen displays details of the active connection. Check the network information in the Link Info screen to verify that you have successfully connected to the selected network.
ZyXEL NWD-170N User’s Guide 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”. 1 Open the ZyXEL utility and click the Profile tab to open the screen as shown. Click Add to configure a new profile. Figure 11 ZyXEL Utility: Profile 2 The Add New Profile screen appears.
ZyXEL NWD-170N User’s Guide Figure 13 ZyXEL Utility: Profile Security 5 This screen varies depending on the encryption method you selected in the previous screen.

ZyXEL NWD-170N User’s Guide Note: Only one profile can be activated and used at any given time. Figure 16 ZyXEL Utility: Profile Activate 8 When you activate the new profile, the ZyXEL utility goes to the Link Info screen while it connects to the AP using your settings. When the wireless link is established, the ZyXEL utility icon in the system tray turns green and the Link Info screen displays details of the active connection.
ZyXEL NWD-170N User’s Guide CHAPTER 3 Wireless LAN Network This chapter provides background information on wireless LAN networks. 3.1 Wireless LAN Overview The following figure provides an example of a wireless network with an AP. See Figure 3 on page 21 for an Ad Hoc network example. Figure 17 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
ZyXEL NWD-170N User’s Guide • 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.
ZyXEL NWD-170N User’s Guide Your NWD-170N 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.
ZyXEL NWD-170N User’s Guide Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption.
ZyXEL NWD-170N User’s Guide CHAPTER 4 Wireless Configuration This chapter shows you how to configure your NWD-170N. 4.1 ZyXEL Utility Screen Summary This section describes the ZyXEL utility screens.

ZyXEL NWD-170N User’s Guide 70 Appendix B
ZyXEL NWD-170N User’s Guide APPENDIX C Wireless Security 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.
ZyXEL NWD-170N User’s Guide EAP-TLS (Transport Layer Security) With EAP-TLS, digital certifications are needed by both the server and the wireless stations 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.
ZyXEL NWD-170N User’s Guide For 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.
ZyXEL NWD-170N User’s Guide 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.
ZyXEL NWD-170N User’s Guide WPA(2)-PSK Application Example A WPA(2)s-PSK application looks as follows. 1 First 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). 2 The AP checks each client's password and (only) allows it to join the network if it matches its password. 3 The AP and wireless clients use the pre-shared key to generate a common PMK.
ZyXEL NWD-170N User’s Guide Figure 53 WPA(2) with RADIUS Application Example Security Parameters Summary Refer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type.

ZyXEL NWD-170N User’s Guide APPENDIX D Setting up Your Computer’s IP Address All computers must have a 10M or 100M Ethernet adapter card and TCP/IP installed. Windows 98/Me/2000/XP 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 2000 and XP.
