Hello, with my Intel(R) Ethernet Server Adapter I350-T4 and others, I get Error 27 in Windows system logs, which indicates loss of connection. Has anyone else solved this?

[Jkell25]

We are using Intel NICs for a long time. With Win7 no problems occured so far. However, when recently switching to Win10 64 bit, all (or most) of our NICs seem to behave strangely. This includes onboards NIC on Siemens IPC 847D (Intel(R) Ethernet Connection I217-LM?), single network controller or the above mentioned Intel(R) Ethernet Server Adapter I350-T4.

Most of the time, the systems work like a charm. But sometimes, the system gets continous network losses (Error ID 27 in Windows System eventlog) and consequently reconnection events (Information ID 33) (see attachement).

We tried all of our very best, but since we are working with video image processing over Ethernet, we need a stable connection.

What else can we do?

Done so far:

Changed potentially errorous components,

Changed energy settings on Windows to "always on",

Changed EEE setting to disabled,

Changed link rate to fixed 1000 mbit/s,

Your help is highly appreciated.

Best regards,

Jan-Hendrik

Hello Michael,

Thank you very much for your kind support. I took a scan from a non-productive PC, since at the moment, I can only provide this. This has not been in prouction so far and can be seen as our clean reference.

If you find anything here, please let me know. In probably two weeks, I can provide scans from another fresh system and from an "older" system, where the networking error occured quite often.

The pattern is not quite easy to recocgnize. Sometimes network connection gets lost 2-3 times per hour, sometimes it hold 2-3 days. We tried to actively force down the network here in our testing environment with high throughput, but could not see the problem as seen at our customer's site.

Thanks again for your support. I highly appreciate it.

Best regards,

Jan-Hendrik

Hello Jkell25, The network adapter that I can see in the SSU that you provided is Intel(R) PRO/1000 GT and not I350-T4. It is best if you can provide the SSU of the actual system that you reported. If you have questions please let us know. Best regards, Michael L. Intel Customer Support Under Contract to Intel Corporation

[Mike_Intel]

Hello Jkell25, I just want to check when can you provide the SSU from the reported system. If you have questions please let us know. Best regards, Michael L. Intel Customer Support Under Contract to Intel Corporation

Hello,

in about 2 weeks, I can present newer logfiles from SSU, when comissioning phase is done.

I appreciate your support in this case.

Best regards,

Hello,

we have compiled a fresh log. However, the problem mentioned earlier did NOT occur sofar. However, can you please check, if the attached configuration is fine?

Thanks for your help. I appreciate it.
