2 Overview of the Wireless Client Utility The Wireless Client Utility is included on the CD that shipped with the TEW-429UB. Install the utility as described in the Quick Start Guide before attaching the TEW-429UB to your computer. IMPORTANT BE SURE TO INSTALL THE WIRELESS CLIENT UTILITY BEFORE YOU ATTACH THE TEW-429UB TO YOUR COMPUTER. ATTACHING THE TEW-429UB BEFORE THE UTILITY IS INSTALLED COULD CAUSE THE INSTALLATION TO FAIL. When the TEW-429UB is installed, it is configured to automatically load when you start your computer. The utility icon displays in the system tray at the bottom-right corner of your screen. Double-click the TEW-429UB icon in the system tray, the following Network screen opens:

8 4. Click WLAN Security. Click the drop-down arrow at Security Mode to choose from the following settings: Disabled (No Encryption) All data sent between the access point and the client is left unencrypted and may be viewed by other wireless devices. WEP (Wired Equivalent Privacy) Encrypts all traffic sent between the access point and the client using a shared key. When using WEP encryption, only access points and PCs using the same WEP Key can communicate with each other WPA/WPA2 WPA encrypts all traffic between the access point and the client using either TKIP or AES encryption. Depending on the authentication protocol selected, each client must authenticate using their own unique username, password, and security certificate. WPA-PSK/WPA2-PSK WPA-PSK or WPA2-PSK is a compromise between WPA/WPA2 and WEP. Like WEP, it uses a pre-shared key that every user of the network must have in order to send and receive data. Like WPA, it uses either TKIP or AES. IT IS RECOMMEDED THAT YOU USE WPA/WPA2 OR WPA-PSK/WPA2-PSKWHENEVER POSSIBLE. WPA (WI-FI PROTECTED ACCESS) PROVIDES STRON-GER ENCRYPTION THAN THE EARLIER WEP (WIRED EQUIVALENT PRIVACY) METHOD. WPA2 PROVIDES EVEN STRONGER ENCRYPTION, AUTHENTICATIONAND KEY MANAGEMENT. IMPORTANT

31 Glossary For unfamiliar terms used below, look for entries elsewhere in the glossary. AD-HOC (IBSS) Ad-hoc mode does not require an AP or a wired network. A network that transmits wireless from computer to computer without the use of a base station (access point). Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). CHANNEL A radio frequency used by a wireless device is called a channel. EAP AUTHENTICATION EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. ENCRYPTION The reversible transformation of data from the original to a difficult-to-interpret format. Encryp-tion is a mechanism for protecting confidentiality, integrity, and authenticity of data. It uses an encryption algorithm and one or more encryption keys. FRAGMENTATION THRESHOLD This is the maximum data fragment size that can be sent before the packet is fragmented into smaller packets. IEEE 802.1X The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an exter-nal RADIUS server. INFRASTRUCTURE (BSS) When a number of wireless stations are connected using a single AP, you have a Basic Ser-vice Set (BSS). ROAMING In an infrastructure network, wireless stations are able to switch from one BSS to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization among other factors.

32 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. TEMPORAL KEY INTEGRITY PROTOCOL (TKIP) Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. USER AUTHENTICATION WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If you do not have an external RADIUS server, use WPA-PSK/WPA2-PSK (WPA -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, clients will be granted access to a WLAN. WEP WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the TEW-429UB and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. WPA/WPA2 Wi-Fi Protected Access (WPA) and WPA2 (future upgrade) is a subset of the IEEE 802.11 i security specification draft. Key differences between WPA and WEP are user authentication and improved data encryption. WPA2 is a wireless security standard that defines stronger encryption, authentication and key management than WPA.

33 Appendix. Maintenance Installing a newer version of the Wireless Client Utility may improve the performance of the TEW-429UB. Before installing the new version, you must uninstall the old one.
