In Win 10 as in Win 8.1 WiFi is disabled in Safe Mode with Networking, so you would normally Ethernet connect.
However, you can manually connect to your SSID in that mode by when on the desktop press CTRL ALT DELETE - click on the wireless icon then on your SSID and select Connect.
Click on Cancel where you should then see a full wireless icon.
You shouldn't have had to change the driver in your Wireless adapter.
