ZyXEL AG-120 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 7 Infrastructure Network There are three ways to connect the wireless client (the AG-120 in station mode) to a network.
ZyXEL AG-120 User’s Guide Figure 8 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 5 on page 49 for detailed field descriptions.
ZyXEL AG-120 User’s Guide Figure 10 ZyXEL Utility: Confirm New Settings 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 AG-120 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 SSID is “SSID_Example3” and the pre-shared key is “ThisismyWPA-PSKpre-sharedkey” in the AP. 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 12 ZyXEL Utility: Profile 2 The Add New Profile screen appears.
ZyXEL AG-120 User’s Guide Figure 14 ZyXEL Utility: Profile Security 5 This screen varies depending on the encryption method you selected in the previous screen. In this example, enter the pre-shared key and leave the encryption type at the default setting. Figure 15 ZyXEL Utility: Profile Encryption 6 Verify the profile settings in the ready-only screen. Click Save to save and go to the next screen.
ZyXEL AG-120 User’s Guide Note: Only one profile can be activated and used at any given time. Figure 17 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. 9 Make sure the selected AP in the active profile is connected to the Internet.
ZyXEL AG-120 User’s Guide Figure 18 ZyXEL Utility: AP: Link Info 2 If you want to change the SSID and enable wireless security for your AG-120, click the Configuration tab and refer to Section 5.3 on page 67 for detailed field descriptions. Note: You can only use WEP when the AG-120 is in AP mode.
ZyXEL AG-120 User’s Guide 36 Chapter 2 Tutorial
ZyXEL AG-120 User’s Guide CHAPTER 3 Wireless LAN Network This chapter provides background information on wireless LAN network. 3.1 Wireless LAN Overview The following figure provides an example of a wireless network with an AP. See Figure 2 on page 24 for an Ad Hoc network example. Figure 20 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 AG-120 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. Configure the wireless LAN security using the Configuration or the Profile Security Setting screen.
ZyXEL AG-120 User’s Guide 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. 3.2.3 User Authentication and Encryption You can make every user log in to the wireless network before they can use it. This is called user authentication.
ZyXEL AG-120 User’s Guide • Shared Key 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 AG-120 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. 3.2.3.2 IEEE 802.
ZyXEL AG-120 User’s Guide 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.
ZyXEL AG-120 User’s Guide In the web configurator, go to the Wireless LAN main screen and then select OTIST. To change the Setup key, enter zero to eight printable characters. To have OTIST automatically generate a WPA-PSK key, select the Yes check box. If you manually configured a WEP key or a WPA-PSK key and you also selected this check box, then the key you manually configured is used. 3.3.1.2 Wireless Client Start the ZyXEL utility and click the Adapter tab.
ZyXEL AG-120 User’s Guide See the user’s guide for more information. 1 In the AP, a web configurator screen pops up showing you the security settings to transfer. After reviewing the settings, click OK. 2 This screen appears while OTIST settings are being transferred. It closes when the transfer is complete. • In the wireless client, you see this screen if it can't find an OTIST-enabled AP (with the same Setup key). Click OK to go back to the ZyXEL utility main screen.
ZyXEL AG-120 User’s Guide 5 If you configure OTIST to generate a WPA-PSK key, this key changes each time you run OTIST. Therefore, if a new wireless client joins your wireless network, you need to run OTIST on the AP and ALL the wireless clients again.
ZyXEL AG-120 User’s Guide CHAPTER 4 Wireless Station Mode Configuration This chapter shows you how to use the ZyXEL utility to configure your AG-120 in wireless station mode.

ZyXEL AG-120 User’s Guide APPENDIX D 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 AG-120 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 AG-120 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 AG-120 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 AG-120 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 AG-120 User’s Guide Figure 71 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. MAC address filters are not dependent on how you configure these security features.
