Hello Mo,I should have asked this question way long time ago. What operating system are you using? I was told that the Zcorp printers did not play nice with Windows 10. I only used Windows 7 Professional for all of my CNC machines so I never had a problem. I would try connecting the CAT5 cable directly to your router to remove any possibility that, that is causing a communications problem. No LEDs on the CAT 5 connection is not a good sign. I can check my screen shots I took months ago and see what I can find. Also I have a video I could post, Somewhere? so you can see my printer booting up as far as I ever got it to.Cismontguy
