Unexpected disconnections - Intel(R) Ethernet Controller I226-V

[Dietoreborn]

Hello,

I am experiencing unexpected disconnections from my ethernet card for a few seconds multiple times during the day.
I proceeded to the following steps:

- Verification that the disconnection does not come from my internet box (no other device suffers from these disconnections and no disconnection in the logs of my box)
- Uninstall and reinstall the driver
- Installation of the last update provided with my motherboard.
- Complete reinstallation of Windows
- Installation of W11 to try to have another version of the driver

Name of my ethernet card : Intel(R) Ethernet Controller I226-V
Driver Date : 09/02/2023 12:00
Driver Version 1.1.4.38
Name of my motherboard : ROG STRIX Z790-F GAMING WIFI

Is it possible to help me please?

Thank you.

Kind Regards.

Hi William / Dietoreborn,

Thank you for posting in Intel Ethernet Communities.

An Intel I226-V was distributed to OEM/vendor to have own build, configuration and settings.

For us to further check the issue, please provide the following details.

- Is it working fine before?

- How often do you encounter the issue?

- Can you share with us on the system report? Guide for the Intel® System Support Utility as following:

https://www.intel.com/content/www/us/en/support/articles/000008563/ethernet-products.html?wapkw=ssu

There is known issue for ASUS mobo:

Asus workaround or updated driver for Intel LAN I226-V

https://rog-forum.asus.com/t5/intel-700-600-series/updated-intel-lan-i226-driver-for-z790-motherboards/m-p/906665

Secondly, proceed with testing if issue persisted:

- Please try to reboot into safe mode with networking or "Enable Safe Mode with Networking" and let us know the result of LAN connection:

The guide to safe mode with networking : https://www.asus.com/my/support/FAQ/1013018/

- Please try to disabled that Energy Efficiency Ethernet and Ultra Low Power Mode settings on the driver. You can do that with the following steps:

1. Open Device Manager.

2. Double-click Network adapter: Intel Ethernet Connection I219-LM

3. Click on the "Advanced" tab, change values for following:

- Energy Efficient Ethernet (EEE) to "Off"

- Speed & duplex to "Auto negotiation"

And this settings, should be apply on your switch or router after ensuring all connected devices have latest drivers:

- Energy Efficient Ethernet (EEE) to "Off"

- Speed & duplex to "Auto negotiation"

Looking forward to hear from you.

Best regards,

Hello B_Y,

Hope you are doing well.

- Is it working fine before ? --> I'm not sure if it was working properly at the beginning, I just remember that the problem started happening more often.

- How often do you encounter the issue ? -->  Several times a day right now, I've had to switch to wifi only.

- Can you share with us on the system report ? --> You can find it in the attachment.

There is known issue for ASUS mobo --> On the topics I could read it does not concern only the Asus motherboards... https://www.guru3d.com/news-story/intel-is-experiencing-network-issues-the-i226-v-controller-is-prone-to-connection-loss.html

Asus workaround or updated driver for Intel LAN I226-V --> Already installed, unfortunately the problem is not solved.

And for the few test --> None of them solved the problem, I had already partly tested following the indications of this topic. (https://community.intel.com/t5/Ethernet-Products/Intel-Communication-Intel-Ethernet-Controller-I226-Series-Random/td-p/1453177/page/2)

Since I can't figure out if it's a hardware or software problem, I don't know if I should wait for a fix from Intel or turn to Asus for the warranty.

Please tell me, if you have other manipulations that could solve the problem.

Thank you for taking the time to help me.

Have a nice day.

Hello William / Dietoreborn,

Thank you for sharing your update.

I'm working directly with our engineering team to help debug this issue. If you are willing we could use your help.

Can you please share with us the following:

1. May I know if you have try the asus driver shared by Murph_9000 , link:

https://dlcdnets.asus.com/pub/ASUS/mb/04LAN/DRV_LAN_Intel_I225_I226_TSD_W11_64_V11438_20230321R.zip

It’s recommended to update driver through the device manager instead of using exe file and the best practice is to: Extract "DRV_LAN_Intel_I225_I226_TSD_W11_64_V11438_20230321R.zip", go to device manager > double click "Intel(R) Ethernet Controller I226-V" > click "Driver" and "Update Driver" > browse my computer for drivers: "DRV_LAN_Intel_I225_I226_TSD_W11_64_V11438_20230321R\W10"

2. Memory dump after the issue reproduced (see instruction below)

3. Collect event viewer log (see instruction below)

4. What is the link partner (switch/mode,/router) being used (company and model), it might be that the issue related to interoperability with specific devices.

After the above information is collected, our next step will be to collect a driver log during the failure. Instructions on how to do this will be forthcoming.

Memory dump:

https://learn.microsoft.com/en-us/troubleshoot/windows-client/performance/generate-a-kernel-or-complete-crash-dump

1. Follow the manually generate memory dump file 

2. After restart MEMORY.DMP will be found in C:\Windows\memory.dmp

Event viewer: In event viewer choose Windows Logs > System > Save All Event As and save the file

Thank you very much for your help.

Hi William / Dietoreborn,

Thanks for the information. We apologize for the inconvenience caused.

Since OEM design their product using Intel component, OEM driver might be optimized/customized for their product which means there are some differences between OEM driver and Intel Generic driver however both driver still can works.

Rest assure that Intel still continues working towards solutions as per other community post below and we will cross check with engineering team for any browser speed issue suggestion:

https://community.intel.com/t5/Ethernet-Products/Intel-Communication-Intel-Ethernet-Controller-I226-Series-Random/td-p/1453177/page/2

We would be grateful if you could provide any link post that have the same issue with you. You may try disable IPv6 however and check Offload suggestion on other website as per below link.

https://www.reddit.com/r/buildapc/comments/vot7no/comment/ij1mmek/?utm_source=share&utm_medium=web2x&context=3

After reviewed the SSU, I noticed that the I226 Driver Version:"1.1.3.28" which seems old and for windows 10.

2) You can do clean driver installation here
