I have no idea why it happens or what specifically triggers it. But here’s what I did to fix it.
Open device manager, by typing
devmgmt.msc
into search box or run dialog. At the device manager expand the Network Adapters and uninstall each and every adapters that exists in there.
then just scan for hardware changes……….
Everything should be back to normal. YESHHHHHHHHHHHHH.
