Ethernet shield not found

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. :frowning: »

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 ! :slight_smile:
