When you try to run ‘netsh wlan start hostednetwork’, you get the following message:
The hosted network couldn’t be started.
The group or resource is not in the correct state to perform the requested operation.
This happens after you disable the newly created hosted network:
Control Panel -> Network Adapters -> Right Click on the Virtual Connection -> Disable
To fix that go to Device Manager (Windows Key + X on Windows 8 and Windows 10). Then, open the network adapters tree, right click on Microsoft Hosted Network Virtual Adapter and click on ‘Enable’. Try now with the command ‘netsh wlan start hostednetwork’ with admin privileges. It should work perfectly.
Note: If you don’t see the network adapter with name ‘Microsoft Hosted Network Virtual Adapter’ try this:
Menu -> View -> Show hidden devices in the Device Manager window.
