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. This enables you to stay connected to your network
while you are at the office, in a meeting room, or at home, with no need for a wired connection.
To establish a wireless connection, do the following:
1. Press Fn+F5 to turn on the wireless feature.
2. Click the wireless-network-connection-status icon in the Windows notification area. A list of available
wireless networks is displayed.
