About SmartWi Connection Utility
The SmartWi Connection Utility functions largely as a switch manager between the various forms of wireless connectivity:
Bluetooth®, WLAN, and WWAN using Cingular Wireless software.
By clicking on each of the three wireless options, the SmartWi Connection Utility switches to the corresponding one.

About the Wireless Switching Window
The Wireless Switching Window is another utility that enables switching between wireless modes. It promotes ease of use
by allowing you to switch between Bluetooth®, WLAN, and WWAN simply by pressing keyboard buttons instead of using the
touch pad (or a separately available USB mouse).

Using the Wireless LAN connection
To use Wireless LAN (WLAN) connectivity, do the following:
Page 7
1.
Click the WLAN button on the SmartWi Connection Utility main window. A status display appears below the
button.
2.
Next, click the status display below the WLAN button. The window enlarges to display WLAN Settings.
If it is the first time connect with WLAN, the Wireless Help Utility will launch automatically and guide you during
initial setup.
WLAN Settings dialog box
To deactivate WLAN connectivity, select Disable for the Status field drop-down box on the WLAN Settings dialog.
By default, WLAN uses theIEEE802.11b/g standard technology for WLAN connectivity. The standard includes the
Wired Equivalent Privacy (WEP) encryption method, which is a security protocol and WiFi Protected Access.
To use IEEE802.11b or IEEE802.11g WLAN connectivity standard only, select them from the Mode field
drop-down box.
Wireless LAN devices using the IEEE802.11a standard and the ones using the IEEE802.11b or g standard cannot
communicate because the frequencies are different. Wireless LAN devices using the IEEE802.11g standard can only
communicate with a device using the IEEE802.11b standard, not with the IEEE802.11a standard.
IEEE802.11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a standard dial up.
IEEE802.11g: The standard speed is 54 Mbps, or about 5 times faster than a Wireless LAN device using the
IEEE802.11b standard.

Configuring the WLAN connection
You can configure your computer to connect to a WLAN in one of two of the following ways:

without an access point device (ad-hoc)

with an acces point device
An ad-hoc network is a network in which a local network is created only by the wireless devices themselves, with no other
central controller or access point device. Each device communicates directly with other devices in the network. For example,
you can set up an ad-hoc network easily at home to communicate between two computers.
A computer communicationg with an access point device is configured as part of an infrastructure network. An infrastructure
network is a network that extends an existing wired local network to wireless devices by providing an Access Point, for
example the Sony Access Point. The Access Point bridges the wireless and wired LAN and acts as a central controller for
the Wireless LAN. The Access Point coordinates transmission and reception from multiple wireless devices within a specific
range.

To configure your computer to communicate without an access point device (ad-hoc), follow these steps:
1.
On the WLAN Settings dialog box, click the Configure WLAN button.
The Wireless Network Connection Properties window displays.
2.
If not automatically selected, select the Wireless Networks tab.
3.
Click the Add... button.
The Association tab opens in the Wireless network properties window.
4.
Enter a Network name (SSID).
You can choose a 32-digit alphanumeric name. If you want to communicate between two or more
computers, you need to configure all these computers using the same network name.
5.
Select Open from the Network Authentication drop-down box.
6.
Select WEP from the Data Encryption drop-down box.
7.
Deselect the The key is provided for me automatically option button. The Network key, Confirm
network key, and Key index (advanced) fieldss activate.
8.
Enter the Network key.
The network key should be 5 or 13 alphanumeric characters long. You can choose whatever you want. If
you want to communicate between two or more computers, you need to configure all these computers
using the same network key.
9.
Enter exactly the same Network key again, for confirmation.
10. Select the check box This is a computer-to-computer (ad hoc) network; wireless access points are
not used.
11. Click OK.
Your Network name appears in the Preferred networks area in the Wireless Networks tab display.
12. Click Advanced.
The Advanced window displays.
13. Select the Computer-to-computer (ad hoc) networks only option button.
14. Click Close.
15. Click OK.
Your computer is ready to communicate with another computer.
To disconnect from a computer-to-computer (ad-hoc) network, click Configure WLAN on the WLAN Settings dialog
box, select the Network Name in the Preferred netowks area, click Remove, and then click OK.

To configure your computer to communicate with an access point device, follow these steps:
Use the VAIO Wireless Utility to guide you through the set up process and provide you with more detailed
information about wireless connections.
