If you want to Win7 share a wired network and realize the Internet, you need two commands to achieve
First enter the Netsh wlan set hostednetwork mode=allow ssid= the network name you want to establish (English format) key= the password you want to set (at least 8 digits) press ENTER
For example my is: netsh wlan set hostednetwork mode=allow ssid=test key=12345678 carriage return
Re-enter the netsh wlan start hostednetwork press ENTER to activate the wireless network. (These two orders are in order)
You can then use your mobile phone to search for and connect to this wireless network
Then go to the local connection--properties--share--tick the two √ on the page, and select "Wireless Network 2" from the Drop-down menu.
Then use the mobile phone to search the wireless network, connected to the Internet
