Getting Started with the TEW-603PI Congratulations on purchasing the TEW-603PI! This manual provides information for setting up and configuring the TEW-603PI. This manual is intended for both home users and professionals. It is not required to read some of the more technical information in this manual (such as in “Wireless LAN Networking” and “Configuring Wireless Security”) to operate and enjoy the TEW-603PI. It is included for your reference only.
Wireless LAN Networking This section provides background information on wireless LAN networking technology. Consult the “Glossary” for definitions of the terminology used in this section. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The TEW-603PI provides various transmission (data) rate options for you to select.
Ad-hoc mode does not require an access point or a wired network. 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). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station.
When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS).
In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network.
In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the TEW-603PI automatically switches to the channel used in BSS (2). Roaming in an ESS network diagram Wireless LAN Security Because wireless networks are not as secure as wired networks, its vital that security settings are clearly understood and applied.
To check wireless LAN security settings for a connection, open the Wireless Client Utility and select the Profile screen. Select the connection you want and click Properties. See “Modifying Profiles”. D ATA E NCRYPTION WITH W E P The WEP (Wired Equivalent Privacy) security protocol is an encryption method designed to try to make wireless networks as secure as wired networks.

Overview of the Wireless Client Utility The Wireless Client Utility is included on the CD that shipped with the TEW-603PI. Install the utility as described in the Quick Start Guide before attaching the TEW-603PI to your computer. IMPORTANT BE SURE TO INSTALL THE WIRELESS CLIENT UTILITY BEFORE YOU ATTACH THE TEW-603PI TO YOUR COMPUTER. ATTACHING THE TEW-603PI BEFORE THE UTILITY IS INSTALLED COULD CAUSE THE INSTALLATION TO FAIL.
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 WHEN THE TEW-603PI IS NOT CONNECTED TO YOUR COMPUTER, MOST SETTINGS IN THE WIRELESS CLIENT UTILITY ARE UNAVAILABLE. SETTINGS OR NOTE BUTTONS THAT ARE NOT AVAILABLE ARE GRAYED OUT. Working with Profiles A profile is a record of the configuration you use to connect to a particular access point.
2. Click Add. The Wireless Client Utility Profile Wizard opens. 3. Type a descriptive name for the profile such as Home or CoffeShop. 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.
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. 6. Select the SSID you want to connect to and click Add To Profile. 7. Click Next. The WLAN Security Configuration screen appears.
8. Select the Security Mode from the drop-down list and then select the appropriate settings for the security mode. 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.
1. Open the Wireless Client Utility and click Profile. 2. Select the profile you want to modify and click Properties.
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. 4. Click WLAN Security. (Refer to “Configuring Wireless Security” for more details on security settings.
WPA 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 WPA-PSK is a compromise between WPA 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.
Checking for Available Access Points To scan for access points using the TEW-603PI, refer to the following. 1. Open the Wireless Client Utility and click SiteSurvey. 2. Available wireless networks are listed. Click Refresh anytime to update the list.
3. Select the network you want and click Connect. Or click Add To Profile if you want to connect later. For details about any of the listed access points, select it from the list and click Detailed Info to see the following screen. (You can also double-click an access point to view the Detailed Info screen. Disabling the Wireless Client Utility You may need to have Windows manage your wireless network settings. In that case, you should disable the Wireless Client Utility.

Glossary For unfamiliar terms used below, look for entries elsewhere in the glossary. A D-H OC (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). C HANNEL A radio frequency used by a wireless device is called a channel.

Troubleshooting P ROBLEMS S TARTING THE 802.11 W IRELESS C LIENT U TILITY P ROGRAM PROBLEM Windows does not auto-detect the TEW-603PI. CORRECTIVE ACTION Make sure the TEW-603PI is properly inserted into the PCI slot and then restart your computer. Perform a hardware scan by clicking Start, Settings, Control Panel and then double-click Add/Remove Hardware. (Steps may vary depending on Windows version). Follow the on-screen instructions to search for the TEW-603PI (Wireless 802.
Infrastructure Make sure that the AP and the associated computers are turned on and working properly. Make sure the TEW-603PI computer and the associated AP use the same SSID. Change the AP and the associated wireless clients to use another radio channel if interference is high. Make sure that the computer and the AP share the same security option and key. Verify the settings in the Profile Security Settings screen. Ad-Hoc (IBSS) Verify that the peer computer(s) is turned on.
