It happened this morning that the Wi-Fi didn’t work anymore on my PC with the latest release of Windows 10 insider preview. The very strange think was that even in the Settings page, the Wi-Fi item was not listed anymore as the first item of the Network & Internet settings page, as you can see from the following screenshot:
Even going to Control Panel > Network and Internet -> Network Connections, a red X was shown for both Wi-Fi and Bluetooth!! I started to think it was an hardware problem, often being the same component the one that handle both the Wi-Fi and the Bluetooth connections … but , on the contrary, it was “only” a SW problem … 😉
I tries to force the connection and disabling/re-enabling the Wi-Fi connection using the right click menu, as suggested in some video I found in youtube … but nothing. the solution in my case was to uninstall the network Wi-Fi drivers from the Device Manager and let Windows re-install them forcing to Scan for hardware changes (right click on the Network adapter item on that window).
The Wi-Fi item was again available and the connections too (even thought I had to insert again all the security keys /PINs).
