WPA2 is backward compatible with WPA. Using Your VAIO Computer > Using the Wireless LAN n 60 N Starting Wireless LAN Communications You first need to establish wireless LAN communications between your computer and an access point (not supplied). See Windows Help and Support for more information. ! For details on how to select the channel that will be used by the access point, see the manual that came with your access point. To start wireless LAN communications 1 Make sure an access point is set up. See the manual that came with your access point for more information. 2 Turn on the WIRELESS switch. 3 Click the VAIO Smart Network icon on the taskbar. 4 Click the switch next to your desired wireless option(s) to toggle it to On in the VAIO Smart Network window. Make sure the WIRELESS indicator light turns on. ! 5 GHz band wireless LAN communications, available on selected models only, are disabled by default. To enable 5 GHz band communication, you need to select the option to use the 5 GHz band or both the 2.4 GHz and 5 GHz bands from the drop-down list for Wireless LAN Settings in the VAIO Smart Network settings window. 5 Click or on the taskbar. 6 Select the desired access point and click Connect. . For WPA-PSK or WPA2-PSK authentication, you must enter a passphrase. The passphrase is case sensitive and must be a text string between 8 and 63 characters in length or a hexadecimal string of 64 characters. Using Your VAIO Computer > Using the Wireless LAN n 61 N Stopping Wireless LAN Communications To stop wireless LAN communications Click the switch next to Wireless LAN to toggle it to Off in the VAIO Smart Network window. ! Turning off the wireless LAN function while accessing remote documents, files, or resources may result in data loss. Using Your VAIO Computer > Using the Bluetooth Function n 62 N Using the Bluetooth Function You can establish wireless communications between your computer and other Bluetooth® devices such as another computer or a mobile phone. You can transfer data between these devices without cables at a range of up to 10 meters in an open area. Bluetooth Security The Bluetooth wireless technology has an authentication function, which allows you to determine with whom you choose to communicate. With the authentication function, you can prevent any anonymous Bluetooth devices from accessing your computer. The first time two Bluetooth devices communicate, a common passkey (a password required for authentication) should be determined for both devices to be registered. Once a device is registered, there is no need to re-enter the passkey. . The passkey can be different each time, but must be the same at both ends. For certain devices, such as a mouse, no passkey can be entered. Using Your VAIO Computer > Using the Bluetooth Function n 63 N Communicating with Another Bluetooth Device You can connect your computer to a Bluetooth device such as another computer, a mobile phone, a PDA, a headset, a mouse, or a digital camera without the use of any cables. Using Your VAIO Computer > Using the Bluetooth Function n 64 N To communicate with another Bluetooth device To communicate with another Bluetooth device, you first need to set up the Bluetooth function. For setting up and using the Bluetooth function, search Windows Help and Support for Bluetooth information. 1 Turn on the WIRELESS switch. 2 Click the VAIO Smart Network icon on the taskbar. 3 Click the switch next to Bluetooth to toggle it to On in the VAIO Smart Network window.

Using Your VAIO Computer > Using the Bluetooth Function n 65 N Stopping Bluetooth Communications To stop Bluetooth communications 1 Turn off the Bluetooth device that is communicating with your computer. 2 Click the switch next to Bluetooth to toggle it to Off in the VAIO Smart Network window. Using Your VAIO Computer > Using the Bluetooth Function n 66 N Notes on Using the Bluetooth Function . The data transfer rate varies, depending on the following conditions: . Obstacles, such as walls, located between devices . Distance between devices . Material used in walls . Proximity to microwaves and cordless telephones . Radio frequency interference and other environmental conditions . Device configuration . Type of software application . Type of operating system . Use of both wireless LAN and Bluetooth functions at the same time on your computer . Size of file being exchanged . Large files may occasionally be corrupted during continuous transfer due to limitations of the Bluetooth standard and electromagnetic interference in the environment. . All Bluetooth devices must be certified to make sure that the applicable standard requirements are maintained. Even if standards are met, individual device performance, specifications, and operation procedures can vary. Data exchange may not be possible in all situations. . Video and audio may not be synchronized if you play videos on your computer with audio output from a connected Bl...
