Hello. I am a homeowner and I’m trying to get the Ethernet ports in all of my rooms working. They do not work in any rooms of the house. I have included a picture of the panel. I am assuming the issue is that there isn’t anything in the “service in” port. There is an Ethernet cord that is running straight to my ATT modem/router from outside. I have tried running a cord from my modem directly to the service in port but that didn’t seem to help. Any idea what the issue is? Panel Picture
