Our company has a product called DCU with W5100, and we have faced some network connection stability issue.
When DCU is connected to switch, ping test is not stable for a while and later then completely out.
If we use port forwarding function with router, then the connection is stable.
Please refer the attached summarized document.
We are looking forward to hearing any experience and solution as well.
