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. Attention: • If you want to use the wireless features on an airplane, check the wireless services with the airline before boarding the airplane. • If there are restrictions on the use of computer wireless features on an airplane, you need to disable the wireless features of your computer before boarding. Depending on the wireless devices installed on your computer, you might be able to use the following wireless networks: • Wireless LAN connection • Wireless WAN connection • Bluetooth connection Chapter 2. Using your computer 37 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 LAN connection, do the following: For Windows 7: 1. Press F8 and follow the instructions on the screen 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 Windows 8: 1. Press F8 to display the list of available wireless networks. Ensure that the Airplane mode is set to off. 2. Double-click a network to connect to it. Provide required information if needed. If you need to connect to different wireless networks in different locations, use the following software to manage multiple network profiles so that the computer automatically connects to an available network when the location changes: • For Windows 7: Use the Access Connections program. For more information, see “Accessing Lenovo programs on the Windows 7 operating system” on page 17. • For Windows 8: Open the Lenovo Settings program and click Location Awareness. For more information, see “Accessing Lenovo programs on the Windows 8 operating system” on page 18. 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. Access Connections gauge status: • Power to the wireless radio is off or no signal. • Power to the wireless radio is on. The signal strength of the wireless connection is poor. To improve signal strength, move your computer closer to the wireless access point. 38 User Guide • Power to the wireless radio is on.

Using the wireless WAN connection Wireless Wide Area Network (wireless 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, such as a city or an entire country, by use of multiple antenna sites or satellite syst...
