Good morning,
I have a w5100 connected to an Arduino UNO. From time to time, the shield gets unreachable until I reboot the whole system or press the “reset” button. Is there a way to reset the shield by software, so that the button doesn’t need to be pressed?
Yes, using MR register setting bit 7 to 1. See 4.1 “common registers”.
Thank you very much for your answer but, in which document is point 4.1 “common registers”?
The question really is: Which command of the Arduino Ethernet Library should I use to reset the shield?

If you know command which is used to write to chip’s register you can use it writing to register #0000 (MR).
Thank you very much
Ethernet.init(53)
Use native library Arduino.
