First, click "run" in the system and enter the cmd command in the "run" column. The DOS window in the operating system will pop up. Here we can enter various doscommands intuitively and conveniently.

Then, we can enter Ping 127.0.0.1 in DOS. This address is a local loop address. If we find that the address cannot be pinged, it indicates that the local machine's TCP/IP protocol is not working properly.

If the above operation is successful, you can Ping it. Then, you can enter IPConfig to view the local IP address and then Ping the IP address (192.168.1.114). The general rule indicates the network adapter (NIC or MODEM) the network adapter is faulty.

Ping the IP address of a computer in the same network segment. Otherwise, the network line is faulty. If the network also contains a router, Ping the IP address of the router in this network segment, general rules: This section of the line has a problem. General rules then Ping the port IP address of the router in the network segment of the target computer. General rules do not cause a route fault. General rules then Ping the IP address of the target computer.

Finally, check a network with DNS service. If the IP address of the target computer still cannot be connected after the IP address of the target computer is pinged in the previous step, you can Ping the network name of the computer, such as Ping www.sina.com.cn, under normal circumstances, the IP address pointed to by the website will appear, which indicates that the local DNS settings are correct and the DNS server works normally. Otherwise, it may be one of the failures; you can also Ping the computer name to detect the failure of WINS resolution (WINS is a service that resolves the computer name to the IP address ).
