I have a Xbox 360 S console, and for whatever reason when I plug my modem in by the Ethernet cord, I get static on my screen. It is barley visible, but it is a new console and I'm just wondering if this is common. I've plugged it into both my router, and my modem, but I get these small static lines that move up the screen vertically. However, it does not do this when I'm connected to the internet via WiFi. Any help on how to get rid of these would be very much appreciated so I don't have to see that static anymore aka snow or little white dots.
