Works like it be suppose to . I like the design compare to the older model . Speedtest be show the corresponding result to what I be sign up for with Comcast . there be a review here that state you need to give you customer id print on the box label instead of the MAC address to Comcast in order to get this add and work . I be not sure how accurate that be . I have a issue get the modem online in my new apartment but that be because of a cable wiring issue , not because MAC Address\/Customer ID number . I have mention this to two different Comcast tech and both tell I that the customer id have nothing to do with it -lrb- before get a tech out to my home and confirm it be a wiring issue -rrb- . I be up and run now and it be be run great . I buy this because I hate give more money away to Comcast or any provider for that matter . Leasing fee on equipment for both internet provider or digital tv be ridiculous when they be already make money off you service .
