I be look to save on some month to month modem rental fee from the cable company and after read the review , decide on this model . I use Comcast and be a little concerned about what I have read when it come to set up this modem with this provider . it be good that I be prepare for some hiccup because you probabaly will run into some . Stay patient ! I start by plug the coaxial cable into the modem , then the power cord , then ethernet into the modem and finally into the computer . click on ie and the comcast set up page initiate . so far so good . I input my #s , hit submit and here 's where the aggrevation begin . it seem like it be progress and then the connection seem to freeze and the modem power down . I attempt to repeat again and again but I do not seem to make any progress until I would completely unplug the modem and basically start from scratch . I then would get to the next Comcast setup screen but would have to power down again , and again . eventually , you will make it through it and once you do , you will have some pretty fast internet . I be speed along at 25 mbp . I want to stress here that I feel that the setup hangup be definitely more Comcast related as other 's have claim . the biggest and only negative so far be the fact that this modem only have one ethernet outlet which can hinder the set up of a home wifus . you may need tech support for you router . I couple mine with a Belkin n150 and after have a 15 minute conversation with the tech -lrb- would have be 10 min . if I could understand she english ! -rrb- , have my household internet rolling . as I mention , be patient and you will be more than happy with this modem . well worth the money .
