ZyXEL AG-220 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 2 on page 22 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-220 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-220 User’s Guide You can use the MAC address filter to tell the AG-220 in AP mode which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information. This type of security does not protect the information that is sent in the wireless network.
ZyXEL AG-220 User’s Guide • Open System 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 Key mode involves a shared secret key to authenticate the wireless station to the AP or peer computer.
ZyXEL AG-220 User’s Guide If 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.
ZyXEL AG-220 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-220 User’s Guide 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-220 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-220 User’s Guide CHAPTER 4 Wireless Station Mode Configuration This chapter shows you how to configure your AG-220 in wireless station mode.

ZyXEL AG-220 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-220 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-220 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-220 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-220 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.
