You may also encounter this situation when using wireless Internet functions to create Routers: Only Network cables and laptops, no wireless routers, but your mobile devices need to access the Internet, will this happen to you? In fact, the solution is really very simple. As long as your laptop is pre-installed with the Win7 system, you can create a wireless router by using the shared wireless Internet access function of the Win7 system, allow your mobile devices to access the Internet. It sounds complicated, but it is not difficult to use it. You only need to follow the steps below. First, find "command prompt" in the Start menu, or directly Type cmd to quickly search, right-click it, and select "Run as administrator ". Run the following command in the command prompt to enable the virtual wireless network adapter: netsh wlan set hostednetwork mode = allow ssid = "win7 ap wow! "Key = wifimima enter the command to enable the virtual wireless network card. This command contains three parameters: 1. mode: whether to enable the virtual Wi-Fi network card. If it is changed to disallow, It is disabled for the Green System favorites, and the virtual network card disappears. 2. Ssid: specify the name of the wireless network, preferably in English. 3. Key: Specify the password of the wireless network. This password is used to encrypt WPA2 securely on the wireless network, which can prevent network attacks. These three parameters can also be used independently as needed. For example, if you only want to disable the virtual Wifi Nic, you only need to use the mode = disallow command. Next, to enable the iPad to use the network that has been connected to the laptop, you need to enable the "Internet Connection Sharing" function. Open the "Network and sharing center" window, click the connected network, and click "properties" in the "Network Status" dialog box ". Open Network connection open connection properties switch to the "share" tab in the Properties dialog box, and select "allow other network users to connect through the Internet connection of this computer ", and select the network connection that allows them to share the Internet here, that is, our virtual Wi-Fi network card. Enable Win7 Connection Sharing and continue to run the following command at the command prompt: netsh wlan start hostednetwork enter the command to enable the Win7 virtual wireless network card to see the "started bearer network" prompt, that is, we have enabled the previously set wireless network. Return to the network connection and we can see that the virtual wireless network card has enabled the specified wireless network. After you enable the Win7 virtual wireless network card and complete all the above settings, you can see the wireless route we enabled in Win7 in the network connection of the iPad, the name is the first time the ssid = character "win7 ap wow!" entered in the command prompt! ", The password is the character "wifimima" after key = ". The way Win7 transformed into a router to share wireless Internet access has been passed on to everyone.
