UDP Dropped Packet on Optiplex 7060 ( Intel Xeon E3 1200/1500 )

Hello,

 

We are experiencing Network troubles on the Dell OptiPlex 7060 Computer with Windows 10 Version 1803 and 1809.

This affect greatly the UDP performance for one of our application.

 

To Demonstrate this we used Iperf3 on another computer with a direct network link.

Here's the output on the OptiPlex Computer :

-----------------------------------------------------------

 

In some cases we even had a Lost packet ratio that goes well beyond 20 %.

 

We suspect that this behavior is linked with an Upgrade from some drivers ( ?? ) :

- If we install a fresh 1809 version without being connected to the internet : the tests with iperf3 are pretty good : 0% of Lost Packets

- if we do the same , but we instead connect the computer to the internet, we experience a high ratio of lost Packets. We tried then to install drivers from intel and Dell to go back to a working state : this had no effect on the network performance.

 

 

Has someone any idea of :

- the source of the problem ? we think it's around the intel 300 chipset ( we have no real clue )

- how to solve the problem after being connected to the internet ? ( rolling back to version that worked )

 

 

 

PS :

 

We made the same test in Safe Mode with Networking.

And this is quite surprising...

Here's the output from iperf3 :

Ok Thanks !

we had just opened an IPS case for this RST Driver problem
