How to set mtu value in Win10 system?

　How to set the mtu value in Win10 system? How to set the mtu value in Win10 system? MTU is the largest transmission unit. Setting the mtu value too large or too small will affect the Internet speed to a certain extent, so we need to set the appropriate mtu value. , can make the network speed the fastest. Recently, a win10 system user wanted to set the mtu value, but did not know how to do it. He was very distressed about this. So how to set the mtu value in win10 system? The editor below will bring it to you Let’s take a look at the steps to set the mtu value in the Win10 system!

The steps to set the mtu value in the Win10 system

1. What is the mtu value?

　mtu is the abbreviation of Maximum Transmission Unit. The Chinese translation is the maximum transmission unit, which refers to the maximum data packet size (in bytes) that can pass through a certain layer of a communication protocol. The maximum transmission unit parameter is usually related to the communication interface (network interface card, serial port, etc.).

2. How to set the mtu value in Win10

1. Right-click on the start menu and select [Command Prompt (Administrator)];

　2. In the command prompt, enter: netsh interface ipv4 show subinterfaces, press the Enter key to view the current mtu value;

　3. Then enter it in the following format: netsh interface ipv4 set subinterface "connection name" mtu=value store=persistent (for example: netsh interface ipv4 set subinterface "WLAN" mtu=1492 store=persistent). Press the Enter key and "OK" appears. ”The prompt indicates that the modification is completed.

## 3. How to get the value?

1. Also open the command prompt (administrator) first, enter: ping -l 1472 -f www. baidu.com (detecting Baidu as an example), requests to send a 1472-byte data packet that is not allowed to be split;

　2. If the transmission fails, it will prompt that it needs If the data packet is split, it means that the mtu value of the current network is smaller than the specified 1472, so we appropriately reduce the size of the data packet (such as 1450), enter: ping -l 1450 -f www.baidu.com Press Press the Enter key;

#　3. If the transmission is successful, it means that the mtu value of the current network is larger than 1450. So we need to slightly increase the value (such as 1460) in order to obtain the most accurate network mtu value, as shown in the figure:

　4. After taking the value, we then pass the above Just set it up.
