K40 Network port stopped working

[Joepat]

Dan,
I Got one of your K40 controllers last year and it worked great. I worked with the zoom group and figured the network chip went out. I need to see what I need to do to send it back in for repair if I can. I did order a new one but I would like to see what I need to do to replace the one that stopped working. I upgraded it to 7.5.5 on the bench and it was connecting to my network, I took it out and connected it to my f16v3 using a comscope factory cable and I couldn't connect. What can I do about my issue. I left about three messages on your website. Help with the one that stopped working.
