Good afternoon GattoNero,
I've updated the driver with the one you said. I noticed that only one "Microsoft Virtual WiFi Miniport Adapter #3" appeared in my Network Connections.
After installing the driver, unfortunately, the error appears like always:
After installation, I also noticed that Bluetooth audio has an dislike of drivers that was mentioned by exclamation sign:
I'm afraid, I need to reinstall the previous drivers in order to have everything without exclamation sign.
I tried reset the wireless to factory settings and tried to logg in but still same issue. WEP ok, WPA2/WPA-PSK nok.
It's weird that I just made HotSpot with my smartphone and the security was WPA2 (AES) and the laptop connected with no issue.
The WLAN filtering is disabled by default. Never used it. (checked also)
If it's possible and if you want, I would accept a teamviewer connection in order for you to have a look. You can access the router and also the issued laptop.
