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.
Your computer comes with a built-in wireless network card and a configuration utility to help you establish
wireless connections and monitor the connection status.
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.
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 wireless-LAN connection status through
Access Connections gauge in the Windows notification area.

Using the wireless-WAN connection
Wireless wide area network (WAN), which uses cellular networks for data transmission, enables you
to establish wireless connections over remote public or private networks. These connections can be
maintained over a large geographical area by use of multiple antenna sites or satellite systems maintained
by wireless service providers.
Some ThinkPad notebook computers come with a built-in wireless-WAN card integrated with some
wireless-WAN technologies, such as 1xEV-DO, HSPA, 3G, GPRS, or LTE. By using the built-in wireless-WAN
card and the configuration utility that comes with your computer, you can establish wireless-WAN
connections.
