I had try that in way that before I uppload program to atmega, I reset W5100 with on board button. A also try to wait 10 (!) seconds before "spi config" line, and before "tcp config" line too, without help.
Reset with port pin... How....where to connect signal for reset?
I connected all pins which are already connected from arduino board which are +5, ss, mosi, miso, sck.
Why everythng is working on arduino board if I have to wait 300ms, which I not doing as you can see from program....
Confusing ...
