Method/step:
1. When the "ping" command is used to determine the smoothness of the DNS server, when "Request Timeout" occurs, we need to first troubleshoot the line, to ensure that the interfaces of routers, Moden, hubs, switches, and NICs are reliable and the network cable is intact.
2. When the hardware lines and devices are correctly connected, we take the following methods to troubleshoot the faults one by one: first, go to the MSDOS interface, run the "Ping 192.168.0.1" command to check the connection between the local machine and the vro (Gateway). If no timeout occurs, the connection is correct.
3. When one of the DNS servers cannot be accessed through the Ping command, we can try to change other DNS servers. For more information about the DNS address, contact your local telecom carrier and obtain it from them. Then, enter the valid DNS in the IP protocol and use it as the preferred DNS.
4. Of course, we can also use public DNS, such as China Telecom's 114.114.114 or 8.8.8.8.
5. Another cause of DNS request timeout failure is the packet loss caused by overload of the carrier server. In this case, we need to bypass the peak hours and perform download operations such as BT during low hours.
6. In addition, a major cause of computer failure to Ping DNS is related to the system. We recommend that you perform full anti-virus processing on the system or install the operating system, this plays an important role in improving DNS access. You can also use network optimization and other related programs to optimize the network.
7. We can also use the volume firewall in 360 security guard to improve the security of the LAN. We need to enable "ARP protection", "automatically bound Gateway", "IP conflict interception", and "external ARP attack interception.
8. When the DNS cannot be pinged or the network connection is unstable, we can use the "network disconnection first aid box" provided by 360 security guard to diagnose the entire network, in this way, you can find out if you cannot access the Internet.
9. Click the "repair now" button to complete the network repair operation, so as to ensure the normal smooth operation of the network.
The above is a small Editor for you to solve the problem that the request timeout occurs when you Ping the DNS on Windows 7. If you also encounter the same problem, you can try the above solution, hope to help you!
