How to solve the request timeout when Win7 computer Ping DNS?

Many users find that they can't open the webpage when they use the Win7 system to access the Internet, and then use the Ping command to check whether the DNS is normal. If the DNS fails to ping or the request times out, this indicates that the network cannot be accessed, not the computer problem, but the network problem. How to solve it? The following small series will share with you the solution! Let's go and have a look!

Method /Step:

1. When using the "ping" command to judge the smooth flow of the DNS server, when the "request timeout" phenomenon occurs, we first need to The line is checked to ensure that the interfaces of the router, Moden, hub, switch, and network card are plugged in reliably, and the network cable is intact.

2, in the case of ensuring that the hardware circuit and equipment are connected correctly, we take the following methods to check the fault one by one: first enter the MSDOS interface, execute the command "Ping 192.168.0.1" to judge this When the connection between the machine and the router (gateway) occurs, when there is no timeout, it indicates that the line connection is correct.

3. When one of the DNS cannot be accessed normally through the “Ping” command, we can try to change other DNS. For specific information about the DNS address, you can consult with and obtain the local telecommunications carrier. The valid DNS is then entered into the IP protocol and used as the preferred DNS.

4, of course, we can also use public DNS, such as Telecom's 114.114.114.114 or 8.8.8.8 to try to connect.

5 Another important cause of DNS request timeout failure is packet loss caused by carrier server overload. For this kind of situation, we need to avoid the rush hour of the Internet, and wait for the BT and other download operations during the low Internet period.

6, In addition, the computer is not able to properly ping Ping DNS is a major reason related to the system, it is recommended to perform a full-scale anti-virus treatment on the system, or important installation of the operating system, which to improve access to the DNS Has an important role. Or it is more effective to optimize the network by using related programs such as network optimization.

7, we can also use the 360 ​​security guards in the "run firewall" to improve the security of the LAN. We need to open the "ARP Protection", "Automatically Bind Gateway", "IP Conflict Interception" and "External ARP Attack Intercept" items.
