This article mainly introduces how to use tracert command to deal with computer network failure, the article is very detailed, has a certain reference value, interested friends must read it!

1. First of all, we need to know the IP address and gateway of the current network, and then detect it. Press Win + R, open run, type cmd, click OK (or press enter) to open the command prompt window

2. Enter: ipconfig / all in the command prompt window, and press enter to execute the command

3. Note here that if there are two network cards in the computer, then the Ethernet card is usually the network card device of the wired network, which is connected locally.

4. If it is a wireless network card network, it is a wireless LAN adapter and wireless network connection.

5. Once you know the IP address, you can use the tracert command to test. The format of the command is: tracert + space + IP address (usually IPv4), press enter to execute the command until the trace is complete; (it takes less time and belongs to normal)

6. For testing, you can first disable the network you are using. Press Win + R key, open run, and enter: ncpa.cpl, press enter key to open the network connection. Right-click on the network in use (either wired or wireless) to disable

7. Then, go to the command prompt window and use the tracert command to check the network status, and there will be an error. From this, we can know that if the network device in the computer goes wrong, it can be detected by using the tracert command.

8. If there is only a problem with an individual website, it may be due to the maintenance of the website. If there is an error in the parsing, you might as well use the ping command to see if the URL makes sense. No, website problem, communication, computer problem. Sometimes, cleaning up the DNS cache can solve problems like this. Enter: ipconfig / flushdns; in the command prompt window (press enter to execute the command to clear the DNS cache)

9. Sometimes, the web page opens slowly, which may be due to problems with the parsing of the DNS server (especially visiting foreign websites at home and visiting domestic websites abroad). If you get DNS automatically, you might as well change it to 8.8.8.8. You can also use the tracert command to test whether the DNS server is valid or fast.

10. You can also use the ping command to find the IP address of this URL, and then enter: notepad "% SystemRoot%\ system32\ drivers\ etc\ hosts" ipconfig / flushdnsexit → to confirm that you can open the hosts file and associate the domain name of the URL with the IP address (because the system will read the file first)

Similarly, you can also use this command to check whether the IP addresses of other hosts in the LAN are open one by one, so as to find the point of failure of shared printers and files.
