    Comcast supposedly upgraded the speed on their Xfinity internet service and indicated that in order to best way to achieve these download speeds was to upgrade to a DOCSIS 3.0 router. The install of the Motorola unit was easy, and the cost wasn't too high. However, I don't think the difference in download speeds is substantially improved.
