DANGER
Your computer has an Ethernet connector. To avoid the risk of electrical shock, do not connect
the telephone cable to the Ethernet connector.

Wireless connections

Wireless connection is the transfer of data without the use of cables but by means of radio waves only.

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 to help you establish wireless connections and
monitor the connection status.
To establish a wireless-LAN connection, do the following:
1. Turn on the wireless feature. See "Using the special keys" on page 18.
2. Click the wireless-network-connection-status icon in the Windows notification area. A list of available
wireless networks is displayed.
3. Double-click a network to connect to it. Provide required information if needed.
The computer automatically connects to an available and remembered wireless network when the location
changes. If the available wireless network is secured, provide the password as required. For more
information, see the Windows help information system.
Tips on 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 cover 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 the
Access Connections gauge in the Windows notification area. The more bars encompassed, the better
the signal is.

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 wireless-WAN card installed, which provides some
wireless-WAN technologies, such as 1xEV-DO, HSPA, 3G, GPRS, or LTE. By using the wireless-WAN
card, you can establish wireless-WAN connections.
