Two Win 7 system computer A dual network card sharing internet

A WIN7 via USB without a line by the Internet, the other using a crossover line connected to, if you have two simultaneous access to the Internet, you can use the bridge, the following methods:
Taking the author's network as an example, The use of the network segment is 192.168.1.X, one of the desktop has been able to access the Internet, the network card is a wireless USB card, and its network card IP is 192.168.1.88, the motherboard with a different network card, the IP set to 192.168.1.90 subnet mask and DNS reference wireless network card settings, Do not set the gateway.

Use a twisted pair to connect the motherboard's network card to another computer's NIC, while the IP of the other computer's network card can be set to 192.168.1.91, and the subnet mask and gateway and DNS reference wireless card settings. After the twisted pair is connected, we again turn on the dual network card Local Connection window, the two local connection all selected and right click, in the pop-up menu select "Bridge", this time need to wait patiently for a while, the "Network Bridge" icon when the connection has been successful, This time just want to set the IP as a normal network card to the bridge TCP/IP configuration, the IP address can be set to 192.168.1.92, subnet mask and gateway and DNS reference wireless network card settings.

This way another computer can be used to share the Internet through the Network Bridge, when not only need to disconnect the twisted pair of wires, very convenient.
