Creating the Hosted Network
In the Command Prompt, use the following command to create the hosted network:
netsh wlan set hostednetwork mode=allow ssid=[YourNetworkName] key=[YourPassword]
Replace “[YourNetworkName]” with the desired name for your Wi-Fi network, and replace “[YourPassword]” with a strong password. The password must be at least 8 characters long.
For example:
netsh wlan set hostednetwork mode=allow ssid=MyWiFiNetwork key=SecurePassword123
Starting the Hosted Network
After creating the hosted network, you need to start it. Use the following command:
netsh wlan start hostednetwork
If the command is successful, you should see a message saying “The hosted network started.”
Sharing Your Internet Connection
To share your internet connection with the hosted network, you need to enable Internet Connection Sharing (ICS) on the internet-connected adapter, as described in the previous section.
Go to “Network Connections,” right-click on the internet-connected adapter, select “Properties,” go to the “Sharing” tab, and check the box that says “Allow other network users to connect through this computer’s Internet connection.”
When prompted to select the adapter for sharing, choose the “Microsoft Hosted Network Virtual Adapter.” This adapter represents the hosted network you created.
