How do I turn the radio on the wireless card

When your computer is switched on, the WiFi radio is almost always transmitting or receiving signals. In certain situations, as in an airplane, signals from the radio may cause interference. Use the following methods if you need to disable the radio and use your notebook without emitting radio signals.
Use the Optional Computer Radio On or Off Switch

If your computer has an external switch installed, use it to switch the WiFi radio on or off. See the computer manufacturer for more information about this switch. If you have Intel® PROSet/Wireless installed, the current state of the radio displays in the Intel PROSet/Wireless main window and on the Taskbar.


Use Intel PROSet/Wireless to Switch the WiFi Radio On or Off

From Intel PROSet/Wireless, the WiFi radio can be switched on or off. The status icon on Intel PROSet/Wireless displays the current state of the radio.

To start Intel® PROSet/Wireless, use one of the following methods:

• Click Start > Programs > Intel PROSet Wireless > WiFi Connection Utility.
• Right-click the Taskbar icon located in the lower right corner of your Windows* Desktop to open the Taskbar menu. Click Configure WiFi.
• Double-click the Taskbar icon to open Intel PROSet/Wireless.

Switch the WiFi Radio On or Off from the Taskbar Icon

To switch the WiFi radio on or off, click the Taskbar icon and select WiFi On or WiFi Off.
