wireless networking - Missing Microsoft Hosted Network Virtual Adapter while setting up WiFi hotspot in Windows 10

I've recently upgraded from Windows 8.1 to Windows 10.

I'm using my computer as a WiFi hotspot, and I can't get that to work in Windows 10.

First, I'm setting up the network:

netsh wlan set hostednetwork mode=allow ssid=[name] key=[password]

I'm trying to start the network:

netsh wlan start hostednetwork

The hosted network couldn't be started.
The group or resource is not in the correct state to perform the requested operation.

Investigating a little, I saw that I need to enable "Microsoft Hosted Network Virtual Adapter" on the Device Manager, but it is not there.

Next, I tried

netsh wlan show drivers

Interface name: Wi-Fi

I have Hosted network supported : No - which I think is the cause of my problem.

How can I fix this issue? Did anything change in Windows 10?

Answer

I solved the issue by updating the drivers, like the comment suggested.

In my very specific case, for Dell Inspiron 3721, I found the drivers at http://downloads.dell.com/published/pages/inspiron-17-3721.html#Drivers , under Dell Wireless 1704 WiFi Driver.
