In Windows Vista and later, there is no Hardware tab. Once the icon for the wireless network card is seen, right-click it and select Enable. If so, select this option and then select Change adapter settings.
If no Enable option is available in the pop-up menu, there may be an option called Open Network and Sharing Center. 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. Look in the Windows notification area to find the icon for Wi-Fi or wireless Internet. In the picture, the F12 key also has an orange LED when disabled and blue when enabled. As seen in the picture, some laptops use the Fn and F12 keys to enable and disable Wi-Fi.
Some laptops enable and disable Wi-Fi using the Fn key and one of the function keys (F1-F12). When enabled, the button should be illuminated as blue, or the switch should be in the On position. Find the button or switch, and make sure it's enabled. It is usually found on the front edge of the laptop or above the keyboard.
Some laptops have an On/Off button or switch for the Wi-Fi connection, like the button shown in the picture. Wi-Fi can be enabled by performing any of the steps below.
