For more information about turning a wireless LAN device on and off and about using the wireless LAN device indicator on your notebook, refer to your model-specific documentation.

■Verify that the antenna(s) are free from obstructions. For information about the number and location of antennas on your notebook refer to your model-specific documentation.

■Verify that you are within optimal range of an access point (for an infrastructure connection) or another wireless-equipped computer (for an ad hoc connection).

■Use the Device Manager utility in your operating system to verify that the correct wireless LAN device driver is loaded and functioning properly.

■Verify that you are using the correct SSID.

■Verify that the wireless encryption settings are correct.

■If you are trying to connect to an ad hoc network, ensure that the channel settings are correct.

❏Type and thickness of building construction materials (brick, steel, concrete, glass, etc.)
