Open Tencent Computer Manager-Toolbox-Wireless Security Assistant.
When you use Tencent computer to check the wireless assistant at home, it will display the devices you are currently using the network, including the machine name, MAC address and IP address, to prevent surfing the Internet. You can change the name of the machine. Adding an existing device means adding another computer (your own or someone you know) used by the network to the trust list, so that you won't be prompted that the device is unknown.
