WiFi technology has changed the habits of many computer users. Over the years, fzhan has not only improved the speed, but also has expanded coverage and security. Great improvement. While win7 is a successful system model of Microsoft, it is very common nowadays. It is mainly very powerful. There are many unexpected internal things in WIN7 system. For example, it is convenient to set WIN7 wireless network card routing settings. Share WIFI Internet access, let's share with you the new features of Windows7 and the mdash;—"virtual Wifi". In short, Windows7 can be based on existing wireless network cards. Then virtualize a wireless network card to support network sharing, let our computer become a wireless router! It seems that nowadays, "virtual" is really everywhere.
Some students may know that before this, in fact, you can also establish a temporary network to share Internet with other Wifi devices. What are the new advantages of virtual Wifi NIC?
Traditional temporary wireless network (Ad Hoc mode) ) is a peer-to-peer network, similar to the "dual-machine interconnection" in the wired network, although it can also achieve Internet sharing, but mainly used for temporary interconnection of two devices, and some devices (such as devices using Android system) Connecting to a temporary wireless network is not supported. There is also a serious problem. Since a wireless network card can only be connected to a wireless network, if you connect to the Internet through a wireless network card, you can no longer use this wireless network card to establish a temporary network and share the Internet.
The virtual Wifi function in Windows7 can virtualize a network card based on a real wireless network card to realize the AP function of the wireless router and solve all problems of the temporary network.
This tempting feature is now taught to everyone:
1. Run the command prompt as an administrator
Because the following steps must be run under administrator privileges, we find it from the start menu ; command prompt & rdquo;, or directly type cmd quick search, right click on it, select “ run as administrator & rdquo;, click “ is & rdquo; in the pop-up user control window. Another way is to hold down the Ctrl and Shift keys and click the shortcut directly, which is even simpler.
2. Enable and set the "Virtual Wifi NIC" mode
Run the following command to enable the virtual wireless network card (equivalent to open the router):
netsh wlan set hostednetwork mode=allow ssid=”Win7 AP WOW!” key=wifimima
There are three parameters in this command:
Mode: Whether to enable the virtual Wifi NIC, disable to disallow, the virtual NIC will disappear.
Ssid: Specify the name of the wireless network, preferably in English.
Key: Specify the password for the wireless network. This password is used for secure WPA2 encryption of the wireless network, which can prevent the network from being blocked.
The above three parameters can be used separately. For example, only mode=disallow can be used to directly disable the virtual Wifi NIC.
