Instructions on using virtual WiFi in win7

If you have installed a wireless NIC driver that supports Virtual WiFi in Windows 7, you will see a virtual Nic In the Control Panel \ network and Internet \ network connection. The device name is: microsoft Virtual WiFi miniprot adapter.
If your system does not have this function and your Nic is intel, you can download the latest driver.Program[32-bit, 64-bit], if not, the system's third-party drivers can also support (such as My USB-tplink, TL-wn321G ). 
How can I start using this virtual Nic? I used to think that this network card is similar to a real network card, but after selecting this network card, I found that it does not have the connection/disconnection option: 

Reference if the computer has a single wireless network adapter. This virtual device is used exclusively for parameter Ming software access point (softap) connections

Only then can you find that if you only have a single wireless network card, this virtual network card can only be a softap, that is, a software virtual AP. This means you can share the network connection on your computer to implement the router function. The procedure is as follows: 

• Open the command line window with administrator permissions (START-> attachment-> command line prompt, right-click to open with administrator permissions)
• Input:Netsh WLAN set hostednetwork mode = allow SSID = windows7ap key = Password(SSID and password are customized based on your preferences)
• Start the adapter and enter:Netsh WLAN start hostednetwork
• Finally, right-click the virtual network card (Microsoft Virtual WiFi miniport adapter) in the Control Panel \ network and Internet \ network connection and select the sharing item. Select an existing network connection to share with it.
• If you search for available networks from wireless NICs on other machines, you will find that an AP was created before. 
• This enables network sharing. Of course, if you think these command line operations are very difficult, there is a software that can help you: connectify. This software should encapsulate the above command line functions.
