## Article

Original : <https://www.arduinotehniq.com/index.php/2017/12/06/solve-problem-with-511-at-w5100-ethernet-shield/> I have an W5100 Ethernet shiled who work ok in home network, but notwork in other network, so I search about this problem and find solution. In my case, manufacturer put a wrong value for a quad resistor, instead 51 ohms (noted 510) was put 510 ohms (noted 511)… ![](https://maker.wiznet.io/uploads/2021/06/1E1TJ-300x225.jpg)
