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. l
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-601PC each time you change access points.
Using the Profile screen you can configure the TEW-601PC 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
Refer to the following to add a profile.
1. Click Profile.
WHEN THE WCB-360A 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.

WEP encryption, only access points and PCs using the same WEP Key can communicate with
each other.
Getting Started with the
TEW-601PC
-- 9
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.
5. Make the changes you want and click TCP/IP Config.
Select the Use IP Changer checkbox. This allows you to bypass your existing wireless TCP/ IP
settings and configure TCP/IP settings for each profile.

Glossary
For unfamiliar terms used below, look for entries elsewhere in the glossary.
AD-HOC
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. Encryption
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 external
RADIUS server.
INFRASTRUCTURE (BSS)
When a number of wireless stations are connected using a single AP, you have a Basic Service
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.

UTHENTICATION
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-601PC 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.
Appendix
This section provides maintenance and troubleshooting procedures. The following topics are
discussed:
• See “Maintenance”
• See “Troubleshooting”
Maintenance
Installing a newer version of the Wireless Client Utility may improve the performance of the
TEW-601PC. Before installing the new version, you must uninstall the old one.
