5Getting 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. The following conventions are used in this manual: THE NOTE SYMBOL INDICATES ADDITIONAL INFORMATION ON THE TOPIC AT HAND. THE TIP SYMBOL INDICATES HELPFULL INFORMATION AND TIPS TO IMPROVE YOUR NETWORK EXPERIENCE. THE CAUTION SYMBOL ALERTS YOU TO SITUATIONS THAT MAY DEGRADE YOUR NETWORKING EXPERIENCE OR COMPROMISE YOUR SECURITY. NOTE LIKE NOTES AND TIPS, THE IMPORTANT SYMBOL INDICATES INFORMATION THAT CAN IMPROVE NETWORKING. THIS INFORMATION SHOULD NOT BE OVER-LOOKED.
6Wireless 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. Options include Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22 Mbps, 24 Mbps, 36 Mbps, 48 Mbps and 54 Mbps. In most networking scenarios, the factory default Fully Auto setting proves the most efficient. This setting allows your TEW-603PI to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the TEW-603PI automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the TEW-603PI gradually increases the transmission (data) rate again until it reaches the highest available transmission rate. Types of Wireless Networks Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-structure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS). To connect to a wired network within a coverage area using access points, set the TEW-603PI operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode. AD-HOC (IBSS) NETWORK
7Ad-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.
8When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS).
9In 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.
10In 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). Wireless LAN Security Because wireless networks are not as secure as wired networks, its vital that security settings are clearly understood and applied. The list below shows the possible wireless security levels on your TEW-603PI starting with the most secure. EAP (Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange. EAP requires interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or the LAN to provide authentication service for wireless stations. 1. Wi-Fi Protected Access (WPA) 2. IEEE802.1X EAP with RADIUS Server authentication 3. WEP Encryption 4. Unique ESSID Roaming in an ESS network diagram DO NOT ATTEMPT TO CONFIGURE OR CHANGE SECURITY SETTTINGS FOR A NETWORK WITHOUT AUTHORIZATION AND WITHOUT CLEARLY UNDERSTANDING THE SETTINGS YOU ARE APPLING. WITH POOR SECURITY SETTINGS, SENSITIVE DATA YOU SEND CAN BE SEEN BY OTHERS.
11To 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”. DATA ENCRYPTION WITH WEP The WEP (Wired Equivalent Privacy) security protocol is an encryption method designed to try to make wireless networks as secure as wired networks. WEP encryption scrambles all data pack-ets transmitted between the TEW-603PI and the access point 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. There are two ways to create WEP keys in your TEW-603PI. • Automatic WEP key generation based on a password phrase called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. • For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the wireless utility and entering them manually as the WEP keys in the other WLAN adapter(s). The TEW-603PI allows you to configure up to four WEP keys and only one key is used as the default transmit key at any one time. THE TEW-603PI SUPPORTS UP TO FOUR 64-BIT, 128-BIT, AND 152-BIT WEP KEYS. THE 152-BIT WEP MUST COMPLY WITH THE WEP SETTING OF YOUR ACCESS POINT OR ROUTER.

(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.
191. Open the Wireless Client Utility and click Profile. 2. Select the profile you want to modify and click Properties.
203. 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.) 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 communi-cate with each other.
21WPA 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. 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. Use DHCP DHCP (Dynamic Host Configuration Protocol) automatically assign IP addresses. Check this radio button if your router is set to DHCP. Use static IP below Check this radio button if you have to enter a static IP address. IT IS RECOMMEDED THAT YOU USE WPA OR WPA-PSK WHENEVER POSSIBLE.

43Glossary 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 external 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.
44SSID The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wire-less 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 wire-less clients using an external RADIUS database. If you do not have an external RADIUS server, use WPA-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-603PI 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 Wi-Fi Protected Access (WPA) 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.
