I buy this after realize that I should have buy my own cable modem year ago to avoid the $ 7\/month rental fee from Comcast for they lousy equipment . I get this up and run with a short phone call to Comcast technical support so they can enter the modem 's MAC address into they system . the setup be easy ; the indicator light on the front be fairly intuitive so you have a idea what the problem be if you internet be not work quite the way it should . the modem can also be access from any web browser on a computer on the local network -lrb- ... -rrb- , provide lot of information about the quality of you internet connection , system uptime , etc. . this be helpful information when I do have a issue with intermittent internet outage and I be able to report this to Comcast to get the problem fix -lrb- it be a problem on they end , not with the Motorola surfboard -rrb- . good price now , too ! this will pay for itself in under a year of use .
