Win7 system to prevent being tricked by others by binding routers and mac addresses

1. First, the win7 user opens the run option in the start menu, enters cmd in the run dialog box, and then presses Enter to enter the dos interface;

2, in the pop-up command prompt window Enter the command ipcongfig /all command, note that there is a space, and then press Enter, you can see a series of information, there is a physical address in the information, followed by the local mac address;

3, finally Log in to the wireless router, and then view the surrounding mac address by view, find the mac address corresponding to your own machine, select the binding, and then complete all operations.

ps: After binding the local mac address and router, only the local can use the wireless network. If there are other users in the same LAN, you need to use the wireless network. By the same method, bind a mac. The address is on the router, so that as long as the mac address is bound to use the wireless network, and the mac address is not bound, it cannot be used normally.
