[Reprinted] Build WiFi hotspots for Windows 7 laptops, and provide tutorials for accessing the Internet from iPhone and Other Devices
Objective: To enable Windows 7 laptop to become a Wi-Fi hotspot in certain conditions (for example, dormitories, hotels, and companies without WiFi but with a network cable that can access the Internet, bring your iPhone, iPad, and itouch online.
The technology comes from the network. I just sent my experiment process for your reference. Because my computer is Windows 7, XP or Vista FY can only find another way to experiment on my own.
1. Microsoft key + R. Open the "run" prompt box and enter "cmd" and press enter, as shown in figure


2. Enter a command prompt
"Netsh WLAN set hostednetwork mode = allow SSID = testnet
Key = test1234 "press ENTER
The meanings of the three parameters are mode = allow: The bearer network mode is set to enable (disallow is disabled)
SSID = testnet: the name of the wireless network broadcast is testnet (you can change it by yourself. It is recommended to use English only)
Key = test123: the wireless network password is test1234 (which can be changed by yourself)
Note: Do not close the command prompt for the moment. You will need to use it later.




3. After the network connection is enabled successfully, a new Nic named "Microsoft Virtual WiFi miniport" will be added to the network connection.
Adapter, rename it as "test WiFi"
If not, the original tutorial said that you only need to update the driver of the wireless network card, but I have it directly. I cannot test this...

4. In the "Network Connection" window, right-click the network drive you have connected to by network cable (in this example, "Local Connection "), select "attribute"> "share"> "allow other network users ...... To connect to the "front tick -- select" test WiFi "from the drop-down menu below and click" OK ".

After this step, the NIC Of The Wired connection network has been shared with the virtual wireless nic "test WiFi.
5. Return to the command prompt and enter "netsh WLAN start hostednetwork"
Enter


By now, your personal WiFi has been successfully established. When you enable the network settings of iPhone 4, you will find the "testnet" wireless network and enter the password to connect to it.


I thought that one step was missing in the original article, that is, setting the IP address. I didn't expect that the virtual WiFi in win7 also had the DHCP service and the IP address could be automatically obtained.
In addition to sharing the Internet with iPhone, iPad, and itouch, I think it can also be shared with other laptops.
There is a laptop, but there is only one network cable that can access the Internet. This method is good, but no experiment is available.
