Anleitung Zusammenfassung
Distance between communication devices . Existence of obstacles between devices . Device configuration . Radio conditions . Ambient environment that includes existence of walls and materials of such walls . Software in use . Communications may be cut off depending on radio conditions. . Actual communication speed may not be as fast as the one displayed on your computer. . Deploying WLAN products compliant with different standards that use the same band on the same wireless network may reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a different standard that uses the same band. 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 64 N Note on the data encryption The WLAN 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 standards, 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. Using Your VAIO Computer > Using the Wireless LAN n 65 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. ...
