I do not know how well the modem work so ignore the star rating , but if you be try to use it on Time Warner Cable 's Wideband service in New York , THIS MODEM will not work . they rep originally tell I that any DOCSIS 3.0 compatible modem would be fine , but when I call in to activate it the provision department tell I that only twc equipment can be activate with the Wideband service . they would not give I a straight answer as to why , but I be fairly sure it be not a technical issue as this modem and the one they provide be basically the same , except they have a router build in -lrb- they give the  Motorola SURFboard Gateway SBG6580 DOCSIS 3.0 Wireless Cable Modem  anyway , Amazon customer service be awesome -lrb- as always -rrb- and provide I with a prepaid shipping label to return the modem to they at no cost ! so prop to Amazon customer support !
