So we have the brown box on the wall outside (of course). The shielded / green cable goes into there, behind the faceplate inside where the box is on the wall outside is that green cable.
Further along in the media panel there is coax, and behind the VM blanking plate upstairs is also white coax. I can't see any white coax anywhere near where the green ethernet is though...
