this be a update after own the modem for just over 30 day : originally give 4 Stars , I have reduce the rating to 1 star . the modem die after a month of use . that leave I stick without service for several day until the weekend could pass and the cable company technician check what the problem be with my Internet Service . after a great deal of checking and cross checking , a new Motorola modem be put in by my cable guy . they sell it for $ 75 -lrb- as oppose to Amazon 's $ 50 -rrb- but offer 1 year on-site warranty with immediate replacement and installation of a problem unit - not so bad a deal if you really need to be online for certain . the new Motorola Surfboard sb5101 be instantly recognize by my Linksys router - so the problem describe below with instalation of the Linksys cable modem wre not encounter . it strike I as odd that there would be less compatability between a Linksys router and modem than between a Linksys router and Motorola modem . I get a LinkSys modem because of the good review , but also because I think it would `` play nice '' with my LinkSys router . my router be the WRT610N dual n-band so it be pretty good . when I get the modem I plug it in and give the MAC Address to my cable company . however , I could not get on the itnernet ; my cable company supply modem have work fine - I just get tire of pay the rental . they have I direct connect the modem to the computer - no problem . the problem be with the router ! the modem and router do not play nice together at all ! since my router be just over a year old , my call to LinkSys let I know they could tell I how to configure the router to get it work ... but it would cost $ 29 . to do so . they product do not work so well together , so they charge to make they work ! I refuse to pay . I get out my LinkSys Router CD , look up my router login and password and other info , then re-install the router . the reinstallation process fix it up so it get on the internet . if you get this modem and have a router , be prepare for a little hassle get it go . first impression of the modem after get it operational with the router be that it seem to provide faster internet access than the old modem from the calbe company do - though only marginally so , but still enopugh to notice . this seem to be a excellent modem and work really well . but , if you have a LinkSys wrt610n -lrb- and probably any other LinkSys router -rrb- be prepare for a little extra work to get the modem go .
