Surfboard modem not registering gigabit router
I have a Motorola Docis 3 gigabit Surfboard cable modem. and an asus rt-n56Ugigabit router. According to the documentation there is a light on the front of the modem (looks kind of like a lightning bolt) that should light up blue when there is a gigabit connection and orange when there is not. I'm not able to get it to register the blue gigabit connection. I'm curious if there is some sort of setting I'm missing to enable gigabit speeds?
