i210 always training to 100Mbs.

Ian_m — Tue, 16 Jan 2024 14:33:40 GMT

We have a COMe PC based carrier board, we have designed, that has two i210 ethernet controllers.

We have successfully programmed these devices (NVM & EEPROM) with MAC address and PCIe ID's and are seen correctly and work in Windows 10.

However both controllers always, about 10 seconds after a network cable is plugged in, end up running at 100Mbs. The smart switch at the other end of the cable indicates the i210's are only advertising a max speed of 100Mbs.

We have copied our EEPROM & NVM code to a PCIe i210 add in card (on same system) and when connected connects almost instantly at 1Gbs.

1. Are there any diagnostics/registers/logs we can observe on the i210 (using Lanconfw64) to see why it ends up at 100Mbs.
2. Could it be a PCB &/or circuit design error ?

Hi lan_m,

Thank you for posting in Intel Ethernet Communities.

Kindly check this Intel® Ethernet Controller I210 Datasheet.

In order for us to investigate further, please provide the information below:

- Your operating system(OS) and build version

- Is it an integrated I210 or an I210 card purchased separately?

- If separately: Please provide us the Serial Number and Part Number as well as Front and Back Picture or i210

- Please provide us the SSU Logs by checking on the Help Guide for the Intel® System Support Utility

The operating system is Windows 10 21H2 build 19044.3570.

This is an integrated i210 we have designed onto a board with a plug in processor module (COM express module).

Attached is a picture of the i210 on the board and System Info from Intel System Support Utility.

Kind regards

Ian

Updated System info with both i210's connected.
