Unable to use the built in wi-fi on laptop after this was upgraded from windows 7 professional to windows 10 professional, as this was bought via ebay I  have no idea as to the history: ie previous apps installed at conversion, but I can use a 802.11b/g/n 300Mbps Wireless USB adapter successfully which is not the way I want to go.  Previously did managed, via tweaking the registry with a youtube suggestion, to get the Wi-Fi to connect, yet another download I installed,no idea was it was now,caused the Wi-Fi to dis-connect and I have been unable to re-connect. The Wi-Fi switch will move to the on position but immediately reverts to the off position when I confirm,  very frustrating, There may have been something; which was originally installed by the previous owner, an installed vpn I have heard, which has caused this problem, no idea as to what that may have been but now impossible to diagnose. Anyone any thoughts?  Thankls Dave

Have you tried deleting the WiFi card in Device Manager and rebooting.
