My internet always worked, only this time nothing works anymore. All Wi-Fi's are not shown and I can't connect to any. What should I do?
Install network drivers away and reinstall, then it works again.
Restart your notebook.
See if there's a switch for Wi-Fi on the notebook that you accidentally turned off.
How do i do that without internet
This is because the driver is still there, it is only installed away and brought out of the system.
