How to enable and disable Wi-Fi

Laptops today all have Wi-Fi (wireless Internet) built-in, allowing people to connect to the Internet from almost anywhere. For security, compatibility, or other reasons, you may want to enable and disable the Wi-Fi on your laptop. To do so, select from the list below and follow the steps.

How to enable Wi-Fi on a laptop

Wi-Fi can be enabled by performing any of the steps below.

Enable with laptop Wi-Fi button

Some laptops have an On/Off button or switch for the Wi-Fi connection, as shown in the picture. It is usually found on the laptop's front edge or above the keyboard. Find the button or switch, and make sure it's enabled. When enabled, the button should be illuminated as blue, or the switch should be in the On position.

Enable with laptop Fn and function key

Some laptops enable and disable Wi-Fi using the Fn key and one of the function keys (F1-F12). As seen in the picture, some laptops use the Fn and F12 keys to enable and disable Wi-Fi. The F12 key also has an orange LED (light-emitting diode) when disabled and blue when enabled, shown in the picture.

Enable Wi-Fi in Windows

Look in the Windows notification area to find the Wi-Fi or wireless Internet icon. Right-click with your mouse on the icon and select the option for enabling (or turning off) the Wi-Fi device in the pop-up menu. If no Enable option is available in the pop-up menu, there may be an option called Open Network and Sharing Center. If so, select this option and then Change adapter settings. Once the wireless network card icon is seen, right-click it and select Enable.

The Wi-Fi adapter can also be enabled in the Control Panel. Click the Network and Sharing Center option, then click the Change adapter settings link in the left navigation pane. Right-click the Wi-Fi adapter and select Enable.

Enable Wi-Fi in Windows Device Manager

Access the Device Manager by right-clicking with your mouse on the My Computer icon on your desktop or in the Windows Start menu. Select Properties from the pop-up menu, click the Hardware tab in the window that opens up and click the Device Manager button.

Find the Wi-Fi adapter in the list of hardware devices. Right-click the adapter name and select Enable from the pop-up menu. If no Wi-Fi adapter is found in Device Manager, the Wi-Fi adapter drivers are not installed.

Enable Wi-Fi in BIOS setup

Finally, there is also the option of enabling the Wi-Fi device in the computer's BIOS setup. However, it is very unlikely the Wi-Fi device would be disabled in BIOS.

Wi-Fi on desktop computers

Wi-Fi adapters are also available for desktop computers. The Wi-Fi button mentioned above is not available with most desktop computers. However, there is the possibility that the Wi-Fi adapter itself (e.g., an external version, like a USB (universal serial bus) Wi-Fi adapter) has an On/Off button or switch. If there is no button or switch, disconnecting the adapter from the computer disables the device.

If the Wi-Fi adapter is not an external device, it is either an internal PCI (peripheral component interconnect) expansion card or built onto the motherboard. When you install the software for the Wi-Fi adapter, an icon shows in the Windows notification area, giving you access to enable and disable the device. Alternatively, you can enable and disable the Wi-Fi adapter through the Device Manager or the BIOS.
