Using Your VAIO Computer
Using Wireless LAN (WLAN)
Using the Sony Wireless LAN (WLAN), all your digital devices with built-in WLAN function communicate freely with each other
through a network. A WLAN is a network in which a user can connect to a Local Area Network (LAN) through a wireless (radio)
connection. This eliminates the need to pull cables or wires through walls and ceilings.
The Sony WLAN supports all normal Ethernet connectivity, but with the added benefits of mobility and roaming. You can still
access information, Internet/intranet and network resources, even in the middle of a meeting, or as you move from one place
to another.
You can communicate without an access point, which means that you can communicate with a limited number of computers
(ad-hoc). Or you can communicate through an access point, which allows you to create a full infrastructure network.
To use the wireless LAN function
You need to set up the wireless LAN network with the SmartWi Connection Utility. See the SmartWi Connection Utility
Help for more information.

Be sure to turn on the WIRELESS switch before starting the SmartWi Connection Utility.
You cannot select the 5 GHz bandwidth, which is used for the IEEE 802.11a standard, on ad-hoc networks.
The IEEE 802.11n draft standard, using the 2.4 or 5 GHz bandwidth, is not available on ad-hoc networks.
