Topic: Ethernet shield not found (Read 2636 times) previous topic - next topic


Hello everyone,

 I try as best I can to understand why my ethernet shield is not recognized by my arduino UNO ...

 Currently I am using the basic IDE examples.  But at each initialization I have:

« Ethernet shield was not found.  Sorry, can't run without hardware.  :( »

 Do you have an idea?  I have absolutely nothing connected on the shield (Pin In / out), the shield is well pressed on the UNO, and connected to my home ethernet switch.  All the LEDs seem to flash correctly anyway.

 It is a shield w5100 from SUNFOUNDER, new, first use

Any help?


Thanks for your answer but I solved by myself my problem yesterday evening... I finally reduced the length of the shield legs by few milimeters and now everything is working fine ! :)
