what is what you call "Arduino Ethernet R2"?
Please post a link to your Ethernet 2.0.0 library. In the IDE you only get the Ethernet2 library in version 1.0.4 (currently).

Why don't you use version 1.x if that works for you? Are you using the original Arduino Ethernet shield or a clone?
I have a clone and it works
Works with library 2.0.0?There were some features when switching from 1.xAre the pins the same?Even the example from the library does not work for me.
yes it works with 2.0.0what error do you get? how does it not work?
Example: SimpleClient.Throws an error: Ethernet shield was not found.Pins connected: SCK,MISO,MOSI - Due 6pin SPI, SS - 10 pin, 3.3v, gnd,reset.
A duplicate of this question was posted on the PJRC forum. Same answer, works fine with the shield plugged into Arduino Due.https://forum.pjrc.com/threads/57416-Arduino-Library-Ethernet-2-0-0-Not-Work!Version 2.0 uses a faster SPI clock speed. Maybe your wiring is good enough for the slower speed the old version used, but not good enough for the faster clock?
