ssid: The name of the wireless network, it is best to use English. (This is livdran2012 as an example, free to set)
key: wireless network password, limited to more than eight characters. (In this case, 100100100 is an example, you can set it freely.)
After entering the command, press the Enter key to run.

After running successfully, open the Network and Sharing Center and click on the left to change the adapter settings.

Entering the Adapter Settings will reveal an additional NIC for the Wireless Network Connection 2 of the Microsoft Virtual WiFi Miniport Adapter. If not, try to update the wireless network card driver.

For your convenience, you can rename wireless network connection 2 to virtual WiFi.

In the network connection, right click on the network connection that is connected to the Internet, select “Properties”→“Share”, check “Allow other network users to connect to the Internet through this computer To connect (N)” and select “Virtual WiFi”.

After the confirmation, a shared NIC icon will appear next to the words "Shared", indicating that "Broadband Connection" has been shared to "Virtual WiFi".

Then, continue to type: netsh wlan start hostednetwork at the command prompt and press Enter to run.
Finally, the red cross of the virtual WiFi disappears, the WiFi base station has been set up and started, and the WiFi-enabled device is used to search for the wireless network established by itself (for example, livdran2012), and enter the password set by itself (for example, 100100100) , you can share the Internet.

Notes
Virtual WiFi is based on Win7 system. The premise of virtual WiFi sharing network is that you must open the computer to connect to the network.
The network status of WiFi devices is completely dependent on the network to which the computer is connected.
