Wiz850io hangs

Hello!

Unfortunatelly I was not able to repeat that state in lab. However, it was constantly repeated in production environment, but this is 600km away… So, I was not able to measure the current.
There is a lot of topics regarding w5500 consumption issue and crashing.
One was, that ferrite bed between AGND and GND should be removed (shortcuted).
The other was about how to connect TCT and RCT.

Can Wiznet guys confirm any of these solutions, to prevent crashing?
Thanks in advance for all the answers!
