Using the wireless-LAN connection
A wireless local area network (LAN) covers a relatively small geographic area, such as an office building or a
house. Devices based on the 802.11 standards can connect to this type of network.
To establish a wireless-LAN connection, do the following:
1. Click the wireless-network-connection-status icon in the Windows notification area. A list of available
wireless networks is displayed.
2. Double-click a network to connect to it. Provide required information if needed.
The computer automatically connects to an available wireless network when the location changes. Open
Network and Sharing Center to manage multiple network profiles. For more information, refer to the
Windows help information system.
Tips for using the wireless-LAN feature
To achieve the best connection, use the following guidelines:
• Place your computer so that there are as few obstacles as possible between the wireless-LAN access
point and the computer.
• Open your computer lid to an angle of slightly more than 90 degrees.
• If you use the wireless feature (the 802.11 standards) of your computer simultaneously with a Bluetooth
option, the data transmission speed can be delayed and the performance of the wireless feature can be
degraded.
Checking the wireless-LAN connection status
You can check the wireless-LAN connection status through the wireless-network-connection-status icon in
the Windows notification area. The more bars encompassed, the better the signal is.
For the Windows 7 operating system, you also can check the Access Connections gauge, the Access
Connections status icon, or the Access Connections wireless status icon in the Windows notification area.
