My wireless internet switch will not turn on.

If your computer will not connect to a wireless Internet signal, one of the first things to check is whether your computer's wireless switch is turned on.

Many laptop computers have a switch located on the exterior of the computer that controls its ability to connect to wireless networks.

This switch can be accidentally turned off, preventing users from connecting to the Internet.

Determine if your computer's wireless connectivity has been disabled by viewing the network icon in the lower toolbar on your computer's desktop.

When there is a disruption in your computer's Internet connection, the icon will have a red X through it. For further information, go to the computer's Network and Sharing Center where you can troubleshoot connectivity issues and view available wireless networks.

If the computer isn't recognizing any wireless connections (and you're sure that there are wireless signals in your area), the likely problem is that the wireless switch is turned off.

Locate the wireless switch on your computer.

It may be located on either side of the laptop or along the back or front.
If you aren't sure whether your computer has a wireless switch, check the user guide that came with the unit.

Determine whether the switch is currently in the "On" or "Off" position.
The switch will be clearly labeled.

Push the switch in the direction of the "On" position to ensure that it is turned on.
If the switch was already turned on, see if there is a keyboard combination that will activate your laptop's wireless capability.

The key combination for your laptop will depend on your computer's manufacturer, but will generally involve a combination of the Function, Control or Alt and the F1 to F12 keys.

Check your user manual for your computer's key combination.

Why don't the internet work? What happens when you try to open it? What type of message are you receiving? Did it work in the past for you?

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.
