All commands in blue need to be run in elevated command prompt. 

1. Check that your Wi-Fi hardware and drivers support wi-fi hotspot:
   netsh wlan show drivers
   Look for line: “Hosted Network Support: Yes“
   
   
2. Create wireless hotpot:
   netsh wlan set hostednetwork mode=allow ssid=my-wifi key=mywifipsw
   Where:
   my-wifi – wireless network SSID (name)
   mywifipsw – wireless network password
3. Start Wi-Fi Hotspot:
   netsh wlan start hostednetwork
   Go to Network connections (Network and Sharing Center > Change adapter settings) and make sure you have new virtual network adapter
   
   If you need to stop Wi-Fi hotspot run:
   netsh wlan stop hostednetwork
4. Share Internet connection:
• Go to Network connections (Network and Sharing Center > Change adapter settings)
• Right click on the live network connection (one connected to the Internet) > Properties > Sharing
• Check “Allow other network users to connect through this computer’s Internet connection” and from the drop down select connection you created in the previous step.
  
  
5. Connect your wireless devices (smartphones, tablets, etc) via the hotspot.
   To show hotspot statistics, run:
   netsh wlan show hostednetwork

After you run through the setup once, in the future you only need to run commands in the step 3 to enable and disable the wi-fi hotspot.
