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.
