Using Your VAIO Computer
Using the 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
To use the wireless LAN function, you first need to set up the wireless LAN function. For setting up and using the wireless
LAN function, search for wireless LAN information using Windows Help and Support. To open Windows Help and
Support, click Start and Help and Support.
!
Be sure to turn on the WIRELESS switch before starting the wireless LAN function.
You cannot select the 5 GHz band, which is used for the IEEE 802.11a standard, on ad-hoc networks.
The IEEE 802.11n draft standard, using the 2.4 GHz or 5 GHz band, is not available on ad-hoc networks.
