Channel Select the Channel you wish to use on your Wireless LAN. 12 Using the Windows Utility Wireless Network Security Network Authentication Data Encryption Passphrase You MUST select the option to match the Wireless LAN you wish to join. The available options are: • Open System - Broadcast signals are not encrypted. This method can be used only with no encryption or with WEP. • Shared Key - Broadcast signals are encrypted using WEP. This method can only be used with WEP. • WPA-PSK - PSK means "Pre-shared Key". You must enter this Passphrase value; it is used for both authentication and encryption. • WPA2-PSK - This is a further development of WPA-PSK, and offers even greater security. You must enter this Passphrase value; it is used for both authentication and encryption. • WPA 802.1x - This version of WPA requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA standard. • WPA2 802.1x - This version of WPA2 requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA2 standard. • WEP 802.1x - This version of WEP requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WEP standard. The available options depend on the Authentication method selected above. The possible options are: • Disabled - No data encryption is used. • WEP - If selected, you must enter the WEP data shown below. This WEP data must match the Access Point or other Wireless stations. • AES, TKIP - These options are available with WPA-PSK, WPA2-PSK, WPA 802.1x and WPA2 802.1x. Select the correct option. For WEP modes, you need to enter the desired value (8~63 characters). Data is encrypted using a 256Bit key derived from this key. Other Wireless Stations must use the same key. Select the desired option, and ensure the Wireless Stations use the same setting. • 64 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 64 Bit Encryption, the key size is 10 chars in HEX (0~9 and A~F). • 128 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 128 Bit Encryption, the key size is 26 chars in HEX (0~9 and A~F). 13 Wireless USB Adapter User Guide ASCII Numerical values, characters or signs are all allowed to be entered. Key Index (1~4) This setting is only available for Open System or Shared Key mode. Network key For WPA-PSK and WPA2-PSK modes, you need to enter the desired value (8~63 characters). Data is encrypted using a 256Bit key derived from this key. Other Wireless Stations must use the same key. Confirm network key Re-enter the value in this field. 802.1x EAP Method There are 5 methods in the drop-down list. • GTC - Generic Token Card. It was created by Cisco. It carries a text challenge from the authentication server, and a reply which is assumed to be generated by a security token. GTC does not protect the authentication data in any way. • TLS - Transport Layer Security. Provides for certificatebased and mutual authentication of the client and the network. It relies on client-side and server-side certificates to perform authentication and can be used to dynamically generate user-based and session-based WEP keys to secure subsequent communications between the WLAN client and the access point. • LEAP - Lightweight Extensible Authentication Protocol. It is a proprietary protocol from Cisco Systems developed to address the security weaknesses common in WEP. • TTLS - Tunneled Transport Layer Security. This security method provides for certificate-based, mutual authentication of the client and network through an encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only server-side certificates. • PEAP - Protect Extensible Authentication Protocol. PEAP transport securely authentication data by using tunneling between PEAP clients and an authentication server. PEAP can authenticate wireless LAN clients using only server-side certificates, thus simplifying the implementation and administration of a secure wireless LAN. Tunnel Select the desired option from the drop-down list. Provision Mode Select the desired mode from the drop-down list. Username Enter the user name into the field. Identity Enter the data in the field. Domain Type the domain name you want into the field provided. Password Enter the password for the tunnel.

Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) 23 Wireless USB Adapter User Guide Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channels are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP & WPA-PSK Both WEP and WPA-PSK are standards for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. WPA-PSK is a later standard than WEP, and is more secure. WPA2-PSK This is a later version of WPA (WPA-PSK). The major change is the use of AES (Advanced Encryption System) for protecting data. AES is very secure, considered to be unbreakable. The PSK (Pre-shared Key) must be entered on each Wireless station. If WPA2-PSK is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WPA2 PSK (Pre-shared Key) Enter the same value on every station and the AP. The PSK must be from 8 to 63 characters in length. The 256Bit key used for the actual encryption is derived from this key. Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widelysupported method is AES. 24 Appendix B - About Wireless LANs Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to "any" or null (blank) to allow connection to any Access Point. Security The Wireless Stations and the Access Point must use the same settings for Wireless security (Disabled, WEP, WPA-PSK, WPA2-PSK, WPA 8021.x, WPA2 802.1x, WEP 802.1x) • If Wireless security remains disabled on the Access Point, all stations must have wireless security disabled. • If Wireless security is enabled on the Access Point, each station must use the same settings. 25 Wireless USB Adapter User Guide FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
