RFID-RC522 problem connecting via RJ45 cable

[Michel - It]

hello everyone, I have created a two modules with 3d printer, I followed another project created by Barte, to open the garage, but I've used it, to turn to disable alarm inside the house, of course I made some changes the original design. Now I finished and running the project, I mounted the RFID-rc522 form and i connected to another module where inside there is Arduino and radio. I connected via RJ45 cable and the distance of 3 meters. The radio module is no longer recognized. my question is spontaneous at this point. How can I fix the problem?

Attention to the fourth pin from the bottom not connected to rc522 form because that cable I used for the LED and therefore not connected to rc522
