Using the Wireless LAN
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.
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 help on setting up a wireless network, click
Start
,
All Programs
, and
VAIO Easy Connect
, and then follow the on-screen instructions of the
Easy Internet Connection Setup
.
!
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.
