Got this modem and right away have the problem that ` niideep ' write in he review . I follow he advice exactly and within a few hour the modem be up and run flawlessly . the key be to hook it up to the cable and leave it alone for about 2 hour . that be what I do . I then have to wrestle with the Comcast activation page for about 45 minute but finally it take and walum , everything be fine . no drop in service at all . the Comcast tech guy be suppose to come and do this for I but I be glad I do it myself now because I think he would have give up have the modem not initialize right away which alot of time it will not . again , read ' niideep 's ' review and follow what he say . this be indeed a great modem . I initially pair this modem with the Mediabridge router you see everyone buying , but the range be not good enough for I so instead I get the Belkin 600 and that hook up very easily and have be great despite the so-so review . again , I think you can not go wrong with this Modem if you be patient . special thanks . to ` niideep ' for he great review and advice which get I through this process .
