Part 2

Mode You can select IEEE 802.11b(B-Only), 802.11b +(B-Plus) , 802.11g (G-Only)standard or B&G Mode (If you choose this option the device will automatically convert the suitable standard ). Profile Enter the profile name and click the Save button to save your configuration, To open the profiles you saved, select the profile from the pull-down menu and then click the Load button. To delete the profiles you saved, select the profile from the pull-down menu and then click the Delete button. Tx Power Level Transmit power level, includes Low Power, Medium-Low Power, Medium Power, Medium-High Power, High Power Fragment Threshold To fragment MSDU or MMPDU into small sizes of frames for increasing the reliability of frame (The maximum value of 4096 means no fragmentation is needed) transmission. The performance will be decreased as well, thus a noisy environment is recommended. RTS Threshold This value should remain at its default setting of 4096. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. -21 -
Preamble Retry limits A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. (Note: If you want to change the Preamble type into Long or Short, please check the setting of AP.) You can set the number of retries if no acknowledgement appears from the receiving station.

Encryption 1-4 Key size To configure your WEP settings. WEP (Wired Equivalent Privacy) encryption can be used to ensure the security of your wireless network. Select one Key and Key Size then fill in the appropriate value/phrase in Encryption field. Note: You must use the same Key and Encryption settings for the both sides of the wireless network to connect KEY1 ~ KEY 4：You can specify up to 4 different keys to decrypt wireless data. Select the Default key setting from the radio button. Encryption：This setting is the configuration key used in accessing the wireless network via WEP encryption. A key of 10 hexadecimal characters (0-9, A-F) or 5 characters (ASCII) is required if a 64-bit Key Length was selected. A key of 26 hexadecimal characters (0-9, A-F) or 13 characters (ASCII) is required if a 128-bit Key Length was selected. A key of 58 hexadecimal characters (0-9, A-F) or 29 characters (ASCII) is required if a 256-bit Key Length was selected. 40 Bit, 128 Bit or 256 Bit. 802.1x Configuration The 802.1X Configuration window is used to configure WEP, CCX and WPA security with 802.1X authentication. -25 -
Protocol This panel enables you to select an authentication protocol. Password This panel is available when EAP-TLS is not selected (either MSCHAP V2 over PEAP is selected with WEP or LEAP is selected for CCX). This panel enables you to enter a login name and password or request that the driver prompt for them when you connect to a network. Personal Certificate This panel is available when EAP-TLS protocol is selected and enables you to select a certificate for authenticating the station. User Name Type in the user name assigned to the certificate. Browse Select a certificate by clicking Browse. Server Certificate You can select to enable or disable server certificate. CCX Configuration None：You may refer to page 25(WEP Configuration). -26 -
802.1x：EAP-TLS is a mutual authentication method, which means that both the client and the server prove their identities. LEAP EAP-TLS Network administers have been taking advantage of the simplified user and security administration that LEAP provides. Before the security authentication is started, you should enter the user name and password or the authentication process will fail. -27 -
WPA settings Preshared Key：Passphrase：Enter the key that you are sharing with the network for the WLAN connection. 802.1x：You may refer to page 25(802.1x Configuration). -28 -
