There is a problem in my /RESET line, and in the logical level of MISO,MOSI,SS,SCK.
For the issue with the /RESET line i have put a 10k resistor, and for the logical level issue, y made a logical converter 3V3 to 5v ,5V to 3V3 with four 2N7000 and a few resistors.
In the Wiz5100 Datasheet says that the IC is 5V tolerant, but in my case doesn’t work without adapt the levels.
Now all is working ok for me.
Thanks for your replies!!!
