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:
3
The Link Information pane provides information on your current connection. This same pane is
shows at the bottom of all screens so you are always aware of your connection status.
A profile is a record of the configuration you use to connect to a particular access point. Without
profiles, you would have to reconfigure the TEW-429UB each time you change access points.
Using the Profile screen you can configure the TEW-429UB to access your home network and your
office network. Each configuration is saved as a profile. Then when you go from the office to your
home you just select the appropriate profile.
CREATING A PROFILE
1. Click Profile
WHEN THE TEW-429UB IS NOT CONNECTED TO YOUR COMPUTER, MOST
SETTINGS IN THE WIRELESS CLIENT UTILITY ARE UNAVAILABLE. SETTINGS OR
BUTTONS THAT ARE NOT AVAILABLE ARE GRAYED OUT.
Working with Profiles
NOTE
YOU CAN CHANGE PROFILES WITHOUT REBOOTING YOUR COMPUTER. (PERHAPS
WHEN WALKING FROM ONE ACCESS POINT TO ANOTHER WITHIN YOUR OFFICE.) IF
YOU USE WINDOWS CONTROL PANEL TO CONFIGURE YOUR CONNECTIONS, YOU
MUST REBOOT THE COMPUTER WHEN CHANGING ACCESS POINTS.
NOTE

2. Click Add. The Wireless Client Utility Profile Wizard opens.
3. Type a descriptive name for the profile such as Office or CoffeeShop.
4. Click the drop-down arrow at Network Mode and select Infrastructure or Ad-Hoc. Choose
Infrastructure when connecting to an access point or wireless router. You will need to know the
SSID of the access point.
Choose Ad-Hoc when connecting directly to another computer without using an access point.
You can type anything for the SSID as long as the same SSID is used on the computer you are
connecting to.
5. In the SSID pane click Browse. The utility performs a site survey and displays the results.
The SSID (Service Set IDentifier) is the name assigned to a wireless Wi-Fi network. All devices
must use this case-sensitive name, which is a text string up to 32 bytes long, in order to
communicate.
5
6. Select the SSID you want to connect to and click Add to Profile.
7. Click Next. The WLAN Security Configuration screen appears.
This screen reflects the security settings detected in the access point you want to connect to.
Security settings vary in complexity and you may have to consult your network administrator for
this information. See “Configuring Wireless Security” for more information.
8. Select the Security Mode from the drop-down list and then select the appropriate settings for the
security mode.
6
9. Click Next
10. Click Save to complete the wizard and save the new profile. (If you do not want to activate the
profile, uncheck the Apply this profile now checkbox.)
MODIFYING PROFILES
You may need to modify settings for a profile. For example, if you purchase a new router, or if your
office administrator provides you with new security settings. Refer to the following to modify a profile.
1. Open the Wireless Client Utility and click Profile.
7
2. Select the profile you want to modify and click Properties, the following window appears
3. Make the changes you want to the Basic Settings and click Advanced Settings.
Unless you have a thorough understanding of wireless networking, it is recommended that
you leave these settings at the defaults.
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-PSK
WHENEVER POSSIBLE. WPA (WI-FI PROTECTED ACCESS) PROVIDES STRON-
GER ENCRYPTION THAN THE EARLIER WEP (WIRED EQUIVALENT PRIVACY)
METHOD. WPA2 PROVIDES EVEN STRONGER ENCRYPTION, AUTHENTICATION
A
ND KEY MANAGEMENT.

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.
