    Hello,

     

    Thank you for posting in Q&A forum.

    To modify the retransmission limit, please kindly follow below steps:

    1.Run "Win + R", input regedit and hit Enter to open the registry editor

    2.Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

    3.Modify the value of InitialRttData as 10. (10000=1 second)

    4.Restart the system and check if it works.

     

    Best regards，

    Jill Zhou
