How to Turn on the Radio on a Wireless Dell Laptop
Turning on the radio of your wireless Dell laptop gives it the ability to pick up on local Wi-Fi networks to give you access to the Internet even if you don't have an ethernet cord or Internet connection plug handy.
Locate the Function button on your dell laptop with the radio icon on it. On most Dell laptops, it is on "F2" and is a blue icon. Keep in mind that it could be on "F3" or another button if your laptop is old or is an out-of-the-ordinary Dell model.
Hold down the Function key, "Fn," and press the "F2" button down for a second.
Wait until the icon pops up in the left-hand side of the task bar or until the red icon over the top of it disappears. Most laptops also have the icon with a light next to it on the side of the laptop for your to check to see if the radio is turned on or not.
Right-click on the radio icon once it turns on to choose a wireless network to connect to.
