How do I turn on wireless capability


To enable or disable wireless functions, you must use the Hot Key combination of "Fn" + "F8". This means to press and hold the "Fn" key (near the windows key), and the press the "F8". This is a toggling function. Each time you press the key, it will turn on or turn off the function. Look for the Wireless Light to ensure that the wireless activated.

Wireless not enabling


Silly question, but are you folding the "Fn" key (bottom left of keyboard) down at the same time as you are pressing the "F12" key?

Wireless capability won't turn on


Make sure you Press and Hold the FN function key then hit the F2 key.

Maybe you don't have your wireless turned on. Look on both sides and in front for the Wireless Switch and turn it on.

Also once the wireless switch is turned on there are keystrokes that can toggle the wireless on or off. Normally you would Press and Hold the FN function key located at the lower left of the keyboard, then hit the correct F1 thru F12 key that toggles the wireless. The correct F1 thru F12 key to hit will have the wireless signal icon )))) on it. Or it might have the icon of a tower with the wireless signal icon )))). Normally the screen will display Wireless On or Wireless Off when you toggle the wireless.

Some laptops might have a wireless button instead of a wireless switch located above the keyboard or on the front or sides.

How do you turn on wifi for dell latitude d610


There is not wireless switch on this model. To turn on your wireless you will need to hold down FN + F2. If this does not turn on your wireless its most probably disabled in the Bios. To enable it, press the F2 key at the Dell Logo on startup, move down to wireless, press enter and move to wireless control, make sure its set to Fn+F2/App, then move down to wireless devices and make sure it set to on. Press Esc, and save changes and exit.

There are three ways to toggle the wireless switch on/off, 1st, Fn + wireless button (F2 or F5), 2nd, the wireless switch on the side of the laptop, 3rd, it can be enabled or disabled under BIOS setup (Tap F2 when turned on the laptop).

My laptop has no wireless switch. I want to put wireless on.


On the bottom left of your keyboard you should find a key marked Fn. On the top right of your keyboard you should find a key marked F11 with a little blue antenna icon on it. While pressing the Fn key, press the F11 key once. this should turn on your wi-fi radio.

If it doesn't, chances are your wi-fi is disabled in BIOS.

  • Make sure the computer is turned off.
  • Press the ON button.
  • Immediately press the F2 key.
  • This should get you into BIOS configuration page.
  • Highlight the "Wireless" option & press space.
  • Highlight the "Wireless Devices" option.
  • In the top middle of your screen you should have a check-box labelled "Enable Internal Wireless WLAN".
  • Make sure this is checked (not empty).
  • Chose the EXIT button (bottom right).
  • The computer will reboot.
  • Your wi-fi should now be on.
Hope this helps.

Press the Fn key. While keeping it pressed, press F2 key. This combination of keys will turn on the wireless. You can use the same key combination to switch off the wireless also. When the wireless is turned on the wifi light glows to indicate it is on.
