First of all,Thanks for reply. I used your code (SurferTim), but I get:
Starting w5100
0.0.0.0
as answer. Does that mean, there ist an SPI error? No SPI Bus-connection? if so, I will have to look with an oscilloscope.
To clarify, when I use the above described EthernetSHield, do I only have to stick it to the mega2560 or do I have to make any more connections or something else?
When I read on the net, it looks like: stick the two PCB together, use the samplecode, it works. I sit like that, or do I have to do something else?

P.S. I use an open source version of English and German. I am allowed to modify, as long as I publish it.
