Do not know if you have not considered a problem: In the case of a good network, when you visit the web page, you may occasionally appear to be “not responding to this site†and “refreshing the pageâ€. Well, Xiao Bian had thought about this issue. After a complex test, I discovered that in addition to being locked into Windows, the IPS service providers (also known as websites) must be honest.
Before solving this problem, we must first understand a network term: MTU (Maximum Transmission Unit), translated as the "maximum transmission unit." It is in charge of the maximum packet size (in bytes) that a layer of the communication protocol can pass. In simple terms, the correspondence between the MTU value on the computer and the website is as follows:
The computer MTU value > network MTU value, the network will automatically split the data, increase the transmission time and website response time;
The computer MTU value <network MTU value, transmission is not an obstacle, although it is a waste of bandwidth but will not let the site appear unresponsive.
If you look at it this way, you should understand that as long as the MTU on the computer is smaller than the website, it is OK.
To know the Windows default MTU, run the command prompt in administrator mode and enter the following command:
Netsh interface ipv4 show subinterfaces
The default MTU for all network cards in the computer will be listed.
To test out the MTU of a website, you also need to enter it at the command prompt
Ping -l 14XX -f (small series on our own website for example)
The meaning of the command is to send to the website a packet that is not allowed to be split, with a size of 14XX bytes. If the following prompt appears, it proves that the MTU of the website is less than the value we tested.
Then just continue to reduce the size, until you can no longer prompt (quietly, most of the site's MTU is about 1460 ~ 1490, everyone in this interval test on the line).
After understanding the MTU of commonly used websites, it is necessary to proceed to modify the MTU on the computer. It is also very simple.
Netsh interface ipv4 set subinterface "connection name" mtu=value store=persistent
If the small editor changes the input is
Netsh interface ipv4 set subinterface "WLAN" mtu=1468 store=persistent
After the change, try again. Is the website's opening speed faster than before? (In fact, no)? The purpose of such a combination of punches is to reduce the chances of problems such as web pages being open. How to flexibly use the old basin friends should understand, such as to repair computer XX, you MTU value is wrong, I reset it for you! Combine "Does your network have Freestyle?
