When the Windows Troubleshooter tells you The wireless functionality is disabled it means that you have the WiFi on your laptop or desktop turned off and you need to turn it on. To activate the WiFi is very easy. First, you have to make sure that it is activated in the physical WiFi button.
In many laptops, you will find it at the top of the keyboard or it may be on one of the keyboard’s function keys, you should notice if one of these keys has the WiFi signal icon. When you find it, you must press it together with the FN key.
Upstairs there is a led/light bulb, which lights when the WiFi has it activated. You should make that light stay on when you press these keys. Doing so may solve the problem. Therefore, you should check if the error is no longer displayed. The wireless functionality is disabled.
