We have developed a board based in Elkart Lake an the two i226-IT connected to PCIE1 and to PCIE2, when the PC goes in sleep mode, after the out of sleep mode, we lost one of the two ethernet based on i226-IT...
There are some modification to do at the NVM to solve the problem of the lost of a Lan?

Hi denislodolo,
Thank you for posting in Intel Ethernet Communities.
Regarding this issue reported, we recommend some action plan that you may follow:
1) Disable Energy Efficient Ethernet (EEE) in Driver Settings
2) Update NVM Firmware.
Kindly contact your motherboard or system manufacturer to inquire about the availability of an NVM firmware update for the i226-IT Ethernet controller.
3)Check your system's BIOS settings to ensure that power management settings are configured correctly, especially those related to PCIe devices.
4)Kindly ensure that you have the latest drivers installed for the i226-IT Ethernet controllers. Updated drivers can address known issues and improve stability. You may download Intel generic driver or reach out for OEM manufacturer for specific NIC drivers
For our Intel generic driver, you can refer to link below:
If you have any other questions, please let me know.

Hello,
the problem is partially solved, the two Lans work, but if I disattach one cable of one
of the two Lans, for more than 10 seconds, I lost this lan, also if I reattach the cable
the lan remain not connected. The same problem also if I put the system in sleep mode,
the lan lost the connection; this happens every time in one of the two, every time the same.
The other lan works fine in all the conditions. Where can I investigate?
Regards
Lodolo Denis
