Hi Jean,
I am Dave, I will help you with this.
The Wi-Fi Direct Virtual Adapter is not related to your WiFi connection, that is for the Hotspot functionality.
The best option is, on another device, like the one you are using to access this forum, go to the support page for your PC on the manufacturers website, then from there, download the installer for the WiFi (WLAN) card device driver.
Then, transfer that driver installer to your PC using a USB drive, and install that driver, and restart (not shut down) your PC.
