Did a windows reset fix the issue temporarily as well?
(btw Comanglia what it does is just removes all the network drivers and preferences. Just hopes that on a restart Windows finds functional drivers I suppose)
This can help solve connection problems you might have after upgrading from a previous version of Windows to Windows 10, as well as fix problems where you can connect to the Internet but not to shared network drives. It removes any network adapters you have installed and the settings for them. After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.
