Windows 10: Intermittent failure to open UDP socket

Summary of Problem:We have a Win 10 application hereafter, “the application/app” that communicates with an external embedded Linux system hereafter “the device” via Wi-Fi. The Wi-Fi connection to the device is provided by an external AP – the PC is connected to that AP via a local ethernet cable from a PCIe NIC.The app opens several TCP sockets and one UDP socket to the device. Occasionally, after suffering an unexpected disconnect from the device e.g., due to poor Wi-Fi signal strength, the application is unable to open the UDP socket to the device TCP sockets are not affected.

Intermittent UDP drops in Windows 10 OS

Hi,
I have a receiver-side NDIS ETL capture. It shows packets in order and all present. I also have an application receiving data off of the socket. The application misses some data, and the data is occasionally in the wrong order.
The application is receiving multicast UDP via a LAN. The loss is apx. 0.01% of data received. While UDP delivery and ordering aren't guaranteed by the protocol and the throughput isn't terrible, I want to understand why the OS would drop the data.
It doesn't need to be lossless, but I want to first identify where the packets are being lost (e.g. in some finite kernel buffer), then find the threshold (e.g. after 64MB of queued data).
Any tips or ideas on steps to take would be greatly appreciated.

 

Error message "missing registry socket"

Hi Harry,

Thank you for bringing up your query on Microsoft Community.

I realize this may be frustrating. Now that you have me with you, let me take care of this.

Winsock or Windows Sockets is a technical specification that defines how Windows network software should access network services.

Let us try the following steps and check if it helps.

Step 1: Perform a Winsock Reset

• Open the Windows Start Screen or Start Menu and type
  cmd in the search box.
• Right-click Command Prompt or cmd in the search results and select
  Run as Administrator.
• Type netsh winsock reset in the Command Prompt window and press
  Enter. Wait for Windows to finish resetting your Winsock configuration.
• Reboot your computer.

Step 2: I suggest you to follow the steps suggested by
