Method One,
The reason for this is that, starting with Vista, Microsoft added a new feature called Window auto-tuning in the TCP/IP stack. The purpose of this function is to allow the operating system to dynamically adjust the size of the data window transmitted on the network based on the real-time performance of the network, such as response time, so as to achieve real-time optimization of network performance. By setting autoTuningLevel to Disabled, you can leave the Data window at its default value.
The settings command is as follows:
netsh interface tcp set global autotuninglevel=disabled
(or highlyrestricted).
Method Two,
1. Run Registry regedit
2. Enter the following option \hkey_local_machine\system\currentcontrolset\services\tcpip\parameters
3. Create a new DWORD (32-bit) value (D) with the name Disabletaskoffload value set to 1
4, restart the computer.
Method Three,
