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, like the button shown in the picture. It is usually found on the front edge of the laptop 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. In the picture, the F12 key also has an orange LED when disabled and blue when enabled.
Enable Wi-Fi in Windows
Look in the Windows notification area to find the icon for Wi-Fi or wireless Internet. 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 select Change adapter settings. Once the icon for the wireless network card is seen, right-click it and select Enable.
Note
In Windows 8, when you right-click the Wi-Fi icon, check to see if Airplane Mode is turned on. If it's turned on, turn it off to enable the wireless network card.
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.
Note
In Windows Vista and later, there is no Hardware tab. Click the Device Manager link in the System window.
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 Wi-Fi adapter) has an On/Off button or switch. If there is no button or witch, 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 expansion card or built onto the motherboard. When you install the software for the Wi-Fi adapter, an icon will then show in the Windows notification area, giving you access to enable and disable the device. Alternatively, you can disable and enable the Wi-Fi adapter through the Device Manager or the BIOS.
