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:
• For Windows 7:
1. Press the wireless-radios control key . Then follow the on-screen instructions to enable the
wireless feature.
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.
• For Window 8.1:
1. Go to the desktop and click the wireless-network-connection-status icon in the Windows notification
area. A list of available wireless networks is displayed.
Note: To display the list, ensure that airplane mode (flight mode) is set to off .
2. Double-click a network to connect to it. Provide required information if needed.
If you want the computer automatically connects to an available network when the location changes, use the
following software to manage multiple network profiles:
• For Windows 7: Use the Access Connections program. For more information, see “Accessing Lenovo
programs on the Windows 7 operating system” on page 14.
• For Window 8.1: Open the Lenovo Settings program and click Location Awareness . For more
information, see “Accessing Lenovo programs on the Windows 8.1 operating system” on page 15.
