I bought a card from from ebay and made the solders by myself, i am not so good for that because it was my first time but anyway I did it finally !!!
Here is what I get after several hours of soldering....
Perfect, I can connect it to the arduino !!!
I did follow the progress from the actual reference site :
http://code.rancidbacon.com/LearningAboutArduinoWIZ810MJ
and after configuring the module I was able to ping (so great ..... !!!).
I did use a cross ethernet cable directly connected to the computer, My ethernet cable was free because i am conneted via wifi ...
I did configure a mini local network (http://www.commentcamarche.net/faq/sujet-2639-windows-xp-mise-en-place-d-un-reseau-prive-virtuel-vpn). sorry it's in french. WIFI connection is not compatible with ethernet local configuration !!!
Here is the code to be qble to enable the ping response (Arduino Code) :
*
Code to test wiznet WIZ810MJ module
See:
Current features:
* Read register/address values
* Write register/address values
* Configure networking to enable ping
* Terrible hacked-together code
