I have a Motorola Surfboard SB6121 Modem with a standard DLINK 10/100 mbps switch. There are currently two active towers on it. However, when I try to connect the ethernet cord from my tower and plug it into my laptop, xbox, or playstation, It won't connect to these devices without needing to reset. Although it wasn't always like this, I was able to do this with the same setup and setting as before.
