How to use the Ping command to determine the network fault

Therefore, these applications have given people a kind of dependence. I would like to ask, if your computer can not access the Internet, it is estimated that you do not even bother to turn on the computer. So, when the computer can't surf the Internet, how can we accurately judge where the network malfunction lies? How to solve this problem quickly? IT Encyclopedia teaches you how to use ping commands to determine network failures.

Method / step

In fact, the computer can not access the Internet can be divided into the following reasons, the system IP settings, network card, MODEM and line failure. To troubleshoot hardware and line problems, we can use the Ping command to quickly detect the status of the network.

Step 1: First, we click on the start run in the system, enter the cmd command in the run bar, and the DOS window in the operating system will pop up, where we can enter all kinds of DOS commands intuitively and conveniently.

Step 2: Next, we can enter Ping 127.0.0.1 in DOS, which is a local circular address. If we find that this address cannot be Ping, it means that the local TCP/IP protocol is not working properly.

Step 3: if the above operation is successful, but Ping can be connected, we can then enter IPConfig to check the local IP address, and then Ping the IP (192.168.1.114). The general rule indicates that the network adapter (network card or MODEM) is working properly, or the network adapter is malfunctioning.

Step 4: Then Ping the failure of the IP, of a computer in the same network segment indicates a failure of the network line; if there is a router in the network, then the IP, of the Ping router on the port of the network segment is not connected, then there is a problem with this section of the line; if the IP, of the port of the Ping router in the network segment where the target computer is located is blocked, the route is faulty; the general rule is to Ping the IP address of the destination machine.

Step 5: Finally, check a network with DNS service. If you still cannot connect to the target computer after the IP address of the Ping in the previous step, you can Ping the network name of the machine. Normally, the IP, pointed to by the URL will appear, which indicates that the DNS setting of the machine is correct and the DNS server is working properly. Otherwise, it may be one of them that has failed. Ping computer names can also detect failures in WINS resolution (WINS is a service that resolves computer names to IP addresses).

When the above five steps are completed, we can easily tell whether there is a network failure in a certain link, the setting that should be reset, and the hardware that should be replaced. In addition, if we want to detect the connection of the network, we can also add-t to the address of the Ping, so that the connection of the Ping can be carried out continuously, which can reflect whether the connection of the network is interrupted or the phenomenon of packet loss occurs. In addition to the Ping command, there is also a lot of small software that can detect the connection to the network and the bandwidth of the broadband line.
