WLAN uses the IEEE 802.11a*/b/g standard or the IEEE 802.11n* draft standard, which specifies the type of technology used. The standard includes the encryption methods: Wired Equivalent Privacy (WEP), which is a security protocol, Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access (WPA). Proposed jointly by the IEEE and Wi-Fi Alliance, both WPA2 and WPA are specifications of standards based on interoperable security enhancements that increase the level of data protection and access control for existing Wi-Fi networks. WPA is designed to be forward compatible with the IEEE 802.11i specification. It utilizes the enhanced data encryption Temporal Key Integrity Protocol (TKIP) in addition to user authentication using 802.1X and Extensible Authentication Protocol (EAP). 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. WPA2, the second generation of WPA, provides stronger data protection and network access control and is also designed to secure all versions of 802.11 devices, including 802.11b, 802.11a, 802.11g, and 802.11n draft standard, multi-band and multi-mode. In addition, based on the ratified IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1X-based authentication. WPA2 is backward compatible with WPA. * See the specifications to find out about the configuration of your computer. The IEEE 802.11b/g standard is a wireless LAN standard, using the 2.4 GHz band. The IEEE 802.11g standard provides higher-speed communications than the IEEE 802.11b standard. Using Your VAIO Computer > Using the Wireless LAN n 47 N The IEEE 802.11a standard is a wireless LAN standard, using the 5 GHz band. The IEEE 802.11n draft standard is a wireless LAN standard, using the 2.4 GHz or 5 GHz band. Wireless LAN devices using the 2.4 GHz band cannot communicate with devices using the 5 GHz band because the frequencies are different. The 2.4 GHz band used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize interference from other devices that use the same band are employed on wireless LAN compatible devices, such interference may cause lower communication speed, narrower communication range, or broken wireless connections. The communication speed varies depending on the distance between communication devices, existence of obstacles between such devices, the device configuration, the radio conditions, and the software in use. In addition, communications may be cut off depending on the radio conditions. The communication range varies depending on the actual distance between communication devices, existence of obstacles between such devices, the radio conditions, the ambient environment that includes existence of walls and materials of such walls, and the software in use. Actual communication speed may not be as fast as the one displayed on your computer. Deploying IEEE 802.11b and IEEE 802.11g products on the same wireless network may reduce the communication speed due to radio interference. Taking this into consideration, the IEEE 802.11g products are designed to reduce the communication speed to ensure communications with IEEE 802.11b products. When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase the communication speed. Using Your VAIO Computer > Using the Wireless LAN n 48 N Communicating without an Access Point (Ad-hoc) An ad-hoc network is a network in which a LAN is created only by 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 an ad-hoc network easily at home. Using Your VAIO Computer > Using the Wireless LAN n 49 N To communicate without an access point (ad-hoc) ! The IEEE 802.11a standard, using the 5 GHz band, and the IEEE 802.11n draft standard, using the 2.4 GHz or 5 GHz band, are not available on ad-hoc networks. 1 Turn on the WIRELESS switch. 2 Click the VAIO Smart Network icon on the taskbar. 3 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. 4 Click Start and Control Panel. 5 Click View network status and tasks under Network and Internet. 6 Click Set up a new connection or network. 7 Select an option to specify the ad-hoc network settings and click Next. 8 Follow the on-screen instructions. Using Your VAIO Computer > Using the Wireless LAN n 50 N Communicating with an Access Point (Infrastructure) An infrastructure network is a network that extends an existing wired local network to wireless devices by providing...
