I have Lenovo X220 notebook (Core i5), Windows 7 SP1 x64. I had Lenovo wireless driver package 15.03.1000.163 (driver 15.3.1.2). I wanted to disable the virtual WiFi hosted network feature due a security reasons by netsh commands:
netsh wlan stop hostednetwork
netsh wlan set hostednetwork mode=disallow
That worked as expected, the "Microsoft VirtualWiFi Miniport Adapter" has disappeared from Device Manager and it also persisted after reboot. No issue yet.
After updating the driver to Lenovo package 15.6.1 (driver 15.4.1.1) one, I can see two virtual wifi adapters now in Device Manager:
Microsoft VirtualWiFi Miniport Adapter
Microsoft VirtualWiFi Miniport Adapter #2
Disabling it by these netsh commands above no longer works (no error reported, but it still remains in Allowed state). I have tried to disable and delete them, reboot, uninstall the driver completely and reinstall ... still the same result. Reverting back to the previous driver 15.03.1000.163 solves it but I would prefer to have the most recent one.
