When I moved into this house, they had these two I believe surface mount ethernet jacks. So, I took an ethernet cord, plugged it into the surface mount ethernet jack and the other part in my computer. However, the ethernet symbol wasn't appearing on my laptop. I tried plugging it into my xbox, but that showed nothing either. Why is this not working? I tried contacting my internet provider and they said "Optimum would not activate those ports since they were not installed by optimum." This is what it looks like
