W5500 schematic

I have made my own board DUE + W5500 , I also used the official schematic as a reference to design it,
When programming a sketch as a chatServer i can get my local ip pretty well , but when I plug a cable into the RJ45 connector , w5500's light won't be on (DUPLED,LINKLED,ACTLED), and it can't be ping on cmd,
if there's any information that u think is helpful please tell me

and my MISO signal is not clean will that cause problem either ?

thanks all

frank.

Post the schematics of your board. Did you use exactly the parts that are mentioned in the posted schematics?

Definitely. But please define what "not clean" means. Do you have a scope screenshot?
