There are three ways to turn off the wireless card on a Dell laptop: (1) Using the BIOS settings, (2) Using the Dell Wireless Utility and (3) using the keyboard hotkey.
Using the BIOS Settings to Turn off the Wireless Card on a Dell Laptop
The most basic way to turn off the wireless card on a Dell laptop is to disable it in the BIOS settings. To enter the BIOS configuration pages, press <F2> as the system boots. Because some models have different BIOS versions and revisions, there can be slight variations in the setup. The best thing to do is consult the manual for your machine or just page through the BIOS settings until you come to the wireless card. Change the setting for the wireless to "Disabled" or "Off," save your changes and then exit the BIOS setup. Your computer will restart without access to its wireless card.
If you are not comfortable entering the system BIOS settings or if you need to toggle the state of your wireless card faster, you can try using the Dell Wireless Utility.
Using the Dell Wireless Utility to Turn off the Wireless Card on a Dell Laptop
Every Dell laptop with wireless comes with the Dell Wireless WLAN Card Utility program. This utility is accessible by clicking the Windows "Start" button and then clicking "All Programs." Browse to the Dell program groups and select "Dell Wireless" and then "Dell Wireless WLAN Utility." This utility can be used to turn off the wireless card on a Dell laptop.
When the program starts, uncheck the "Enable Radio" checkbox.
Depending on which version of the Dell Wireless WLAN Utility your computer has, you may need to right click the Dell Wireless Utility tray icon and select "Disable Radio" from the menu.
Just in case neither of the first two methods appeal to you, there is one more method to turn off the wireless card on a Dell laptop: the hotkey.
Using the Dell Keyboard to Turn off the Wireless Card on a Dell Laptop
Dell laptops come with a hotkey that will toggle the wireless card between "Enabled" and "Disabled." On most models, it is done by pressing the <F2> key. You have to be careful about this though because the Dell BIOS has an option to set the default behavior of the function keys. In the BIOS, you can choose to have the <F2> function to be the default action of the <F2> key. In that case, the wireless card is toggled by pressing the <Fn> key and <F2> simultaneously.
If you have not changed the default action in the BIOS, <F2> will toggle wireless. Because this is the default setting for most units, many people understandably disable their wireless card by accident. If this happens, you could end up paying for a service call when all you need to do is hit <F2> again to turn the wireless card back on.
