  W5500 Ethernet module would not work on my Arduino.

The wireless module was driven by a voltage divider to drop the levels suitable for it. The value for R1 was 10K and R2 was 15K.   The module plugs in a socket and next to socket are posts. I used the posts to wire up the Ethernet module.

It appears that the divider did not provide enough current to drive the W5500. You can use level shifters , maybe a lower resistance divider, or directly drive with 5V.
