Bad batch of W5500 shields

I’ve got a batch of W5500 shields (1826) that I recently purchased that fail to create a link with certain switches. I tried removing R17 from the board, which should disable auto-negotiation, but that didn’t work. I have a few from what I believe is batch 1836 that work perfectly fine with the same networking equipment. What changed?

Hi rasetten

Is there a difference between the 1826 and 1836 board versions?

If there is no board version difference, there is no change.

Thank you
