Setting Up Your Inspiron Laptop
Enable or Disable Wireless
To turn on wireless, with the computer turned
on, press the wireless key 
on the keyboard. A confirmation of your selection appears on the screen.
The wireless key allows you to quickly turn all of your wireless radios (Bluetooth and WiFi) off, such as when you are asked to disable all wireless radios on an airplane flight. To turn off all wireless radios, press this key once. Pressing it again returns your wireless radios to their respective states they were in before you turned off wireless.
