like the tittle say ; I think this modem be great ! its a great deal since I have see older model sell at walmart for about the same price . I do not want to rent a modem from Comcast and I be a bit worried at first that the tech be go to tell I he could not use this one , but it all work perfectly ! I have the modem connect directly to my router for wifus and I have fast internet on all my device at home -lrb- a blue-ray player w \/ wifus , two smartphone and two laptop -rrb- . it be super fast and have not give I any issue since I buy it back in Novermber 2011 .
