The wireless client is labeled C and the access point is labeled AP. Figure 5 Infrastructure Network There are three ways to connect the wireless client 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 AG-120 User’s Guide Figure 6 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 on page 42 for detailed field descriptions.
ZyXEL AG-120 User’s Guide Figure 8 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.

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 22 for an Ad Hoc network example. Figure 16 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 Profile Security Setting screen.
ZyXEL AG-120 User’s Guide 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 Setting screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s). • Enter the WEP keys manually. Your AG-120 allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys and only one key is used as the default key at any one time. 3.2.1.1.
ZyXEL AG-120 User’s Guide 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.
ZyXEL AG-120 User’s Guide 3.3.1.1 AP On the P-334U, you can enable OTIST using the OTIST button or the web configurator. 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 about two seconds. 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.
ZyXEL AG-120 User’s Guide 3.3.2 Starting OTIST Note: You must click Start in the AP OTIST web configurator screen and in the wireless client(s) Adapter screen all within three minutes (at the time of writing). You can start OTIST in the wireless clients and AP in any order but they must all be within range and have OTIST enabled. 1 In the AP, a web configurator screen pops up showing you the security settings to transfer. After reviewing the settings, click OK.
ZyXEL AG-120 User’s Guide have the wireless client search for an OTIST-enabled AP, there is no timeout; click Cancel in the OTIST progress screen to stop the search.) 3 When the wireless client finds an OTIST-enabled AP, you must still click Start in the AP OTIST web configurator screen or hold in the Reset button (for one or two seconds) for the AP to transfer settings.

ZyXEL AG-120 User’s Guide 76 Appendix B Management with Wireless Zero Configuration
ZyXEL AG-120 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 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 52 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.
