Doubts abouts infra-red Ir e18 d80nk

Hello guys...

I'm doing a new project to my school and I'm using Ethernet Shield and infra-red sensor (Model: IR E18 D80nk).

The Sensor works very well, so when I put the Ethernet Shield and connect all wires in the same place where ones were, the infra-red wokrs all the time, same without anything in front of its.

If someone knows, help me. Thanks :slight_smile:
