It utilizes the enhanced data encryption TKIP (Temporal Key Integrity Protocol) in addition to user authentication using 802. 1X and EAP (Extensible Authentication Protocol)). Data encryption protects the vulnerable wireless link between clients and Access Points. Besides that, there are other typical LAN security mechanisms to ensure privacy, such as: password protection, end-to-end encryption, virtual private networks, and authentication. Wireless LAN devices using the IEEE 802. 11a standard and those using the IEEE 802. 11b or g standard cannot communicate because the frequencies are different. Wireless LAN devices using the IEEE 802. 11g standard can only communicate with a device using the IEEE 802. 11b standard, not with the a standard. IEEE 802. 11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a standard dial up. IEEE 802. 11g: The standard speed is 54 Mbps, or about 5 times faster than a Wireless LAN device using the IEEE 802. 11b standard. nN 52 Using your VAIO computer Communicating without an Access Point (computer-to-computer) A computer-to-computer network is a network in which a local network is created only by the wireless devices themselves, with no other central controller or Access Point. Each device communicates directly with other devices in the network. You can set up a computer-to-computer network easily at home. To communicate without an Access Point (computer-to-computer), proceed as follows: 1 Turn on the wireless switch. To communicate with an Access Point (infrastructure), proceed as follows: 1 2 Set up the Access Point as described in the manual delivered with the Access Point and turn on the Access Point. If your computer supports Bluetooth technology, the Wireless Device Switch dialog box appears. Select the Enable 2. 4 GHz Wireless LAN check box and deselect the Enable Bluetooth Device check box, then click the OK button. Right-click the network icon in the taskbar displaying Wireless Network Connection. The Wireless Network Connection dialog box appears. If the Access Point is not displayed, click the Refresh network list link. Select the network you want to use and click the Connect button. The Wireless Network Connection dialog box appears. Type the Network key if applicable and click the Connect button. After 30 seconds, the connection is established. Once you are connected, you see the word Connected appear behind the name of the network. For more information about setting up an access point, see the documentation supplied with your Access Point. 3 4 5 6 nN 55 Using your VAIO computer How to select a Wireless LAN channel In an 802. 11b/g configuration, channels 1 to 13 can be used. (a) With an Access Point ("Infrastructure") The channel used will be the channel selected by the Access Point. For details on how to select the channel that will be used by the Access Point, please refer to the corresponding instruction manual. (b) Without Access Point ("computer-to-computer") If the Wireless connection is initiated by the VAIO computer, channel 11 will be selected. [. . . ] If you are not using the computer for an extended period of time, remove the battery pack from the computer to prevent damage to the battery. If, after fully charging the battery pack, the battery power is still low, the battery pack may be reaching the end of its life and should be replaced. You do not need to discharge the battery before recharging. If you have not used the battery pack for a considerable amount of time, recharge the battery. nN 123 Precautions On using headphones Road safety ­ Do not use headphones while driving, cycling, or operating any motorized vehicle.
