ZyXEL G-220 v2 User’s Guide CHAPTER 1 Getting Started This chapter introduces the ZyXEL G-220 v2 and prepares you to use the ZyXEL Utility. 1.1 About Your ZyXEL G-220 v2 The ZyXEL G-220 v2 is an IEEE 802.11g compliant wireless LAN adapter. The following lists the main features of your ZyXEL G-220 v2. See the product specifications in the appendix for detailed features. • Automatic rate selection. • Security: WEP (Wired Equivalent Privacy), IEEE 802.
ZyXEL G-220 v2 User’s Guide Figure 1 Application: Infrastructure 1.1.1.2 Ad-Hoc In case you prefer to set up a small independent wireless workgroup without an AP, use the Ad-Hoc mode. Ad-hoc mode does not require an AP or a wired network. Two or more wireless clients communicate directly to each other.
ZyXEL G-220 v2 User’s Guide 1.1.1.3 Access Point Mode You can set the ZyXEL G-220 v2 in access point mode. The following figure shows a network example. Figure 3 Application: Access Point Mode In the example, the ZyXEL G-220 v2 is installed on computer A and set to operate in access point mode. Computer A shares Internet connection to the wireless LAN, so wireless stations B and C can access the Internet. 1.
ZyXEL G-220 v2 User’s Guide 1.5 Accessing the ZyXEL Utility After you install and start the ZyXEL Utility, an icon for the ZyXEL Utility appears in the system tray. Note: When the ZyXEL Utility system tray icon displays, the ZyXEL G-220 v2 is installed properly. When you use the ZyXEL Utility, it automatically disables the Windows XP wireless configuration tool. Figure 4 ZyXEL Utility: System Tray Icon The color of the ZyXEL Utility system tray icon indicates the status of the ZyXEL G-220 v2.
ZyXEL G-220 v2 User’s Guide 1.6.1 Site Survey After you install the ZyXEL Utility and then insert the ZyXEL G-220 v2, follow the steps below to connect to a network using the Site Survey screen. 1 Make sure a wireless network is available and within range. 2 Open the ZyXEL Utility and click the Site Survey tab to open the screen as shown next. 3 Click Scan to search for available wireless networks.
ZyXEL G-220 v2 User’s Guide Figure 6 ZyXEL Utility: Security Setting 6 Verify that you have successfully connected to the selected network and check the network information in the Link Info screen. If the ZyXEL G-220 v2 is not connected to a network, the fields in this screen are blank. Figure 7 ZyXEL Utility: Link Info 1.7 ZyXEL G-220 v2 Modes You can set your ZyXEL G-220 v2 to operate in either wireless station or access point (AP) modes.
ZyXEL G-220 v2 User’s Guide In access point mode, your ZyXEL G-220 v2 functions as an access point. This allows you to set up your wireless network without using a dedicated AP device. Up to 16 wireless stations can associate to the ZyXEL G-220 v2 to form a wireless network. Refer to Section 1.7.1 on page 25 and Chapter 4 on page 53 for more information. Note: With WZC, you cannot use the ZyXEL G-220 v2 as an access point. 1.7.

ZyXEL G-220 v2 User’s Guide CHAPTER 2 Wireless LAN Network This chapter provides background information on wireless LAN network. 2.1 Wireless LAN Overview This section describes the wireless LAN network terms and applications. 2.1.1 SSID The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network. Wireless devices must have the same SSID to communicate with each other. 2.1.2 Channel A radio frequency used by a wireless device is called a channel. 2.1.
ZyXEL G-220 v2 User’s Guide Configure the wireless LAN security using the Configuration or the Profile Security Setting screen. If you do not enable any wireless security on your ZyXEL G-220 v2, the ZyXEL G220 v2’s wireless communications are accessible to any wireless networking device that is in the coverage area. 2.2.
ZyXEL G-220 v2 User’s Guide 2.2.3 WPA(2) 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. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption.
ZyXEL G-220 v2 User’s Guide 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 G-220 v2 User’s Guide Figure 12 WPA(2) with RADIUS Application Example 2.3 Encryption Type The IEEE 802.11b/g standard describes a simple encryption method between the wireless stations and AP. Three encryption types are defined: Auto, Open System and Shared Key. • Open System mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP do not share a secret key.
ZyXEL G-220 v2 User’s Guide Select Auto to have the ZyXEL G-220 v2 automatically use short preamble when all access point/wireless stations support it, otherwise the ZyXEL G-220 v2 uses long preamble. Note: The ZyXEL G-220 v2 and the access point/wireless stations MUST use the same preamble mode in order to communicate. 2.
ZyXEL G-220 v2 User’s Guide 2.5.1.2 Wireless Client Start the ZyXEL Utility and click the Adapter tab. Select the OTIST check box, enter the same Setup Key as your AP’s and click Save. 2.5.2 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.
ZyXEL G-220 v2 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.

This denotes that this wireless network is your preferred network. Ordering your preferred networks is important because the ZyXEL G-220 v2 tries to associate to the preferred network first in the order that you specify.

ZyXEL G-220 v2 User’s Guide 88 Appendix D Management with Wireless Zero Configuration
ZyXEL G-220 v2 User’s Guide APPENDIX E Types of EAP Authentication This appendix discusses some popular authentication types: EAP-MD5, EAP-TLS, EAPTTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. Your wireless LAN device may not support all authentication types. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method.
ZyXEL G-220 v2 User’s Guide PEAP (Protected EAP) Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.
ZyXEL G-220 v2 User’s Guide WPA(2) 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. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption.
ZyXEL G-220 v2 User’s Guide By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network. The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials.
ZyXEL G-220 v2 User’s Guide Figure 63 WPA-PSK Authentication WPA(2) with RADIUS Application Example You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server.
