Wifi problem in Windows 10?

[Petie]

I've seen this happen pretty frequently with Windows 10. The optimal solution here is to delete the wireless card from the device manager, uninstalling any drivers with it, and then download and install the latest drivers for the card. Obviously, this is difficult to do when you can't download the drivers to begin with so start by running System Restore and go back to the day before it happened and then update the driver.
