the earlier review be right about this device . once properly set up , it run without a hitch , and we internet connection seem to be a bit faster than with the older modem it replace , which we have foolishly rent from Comcast for year . I do , however , have some trouble get it register with Comcast . I have read the review say that you just plug it in and fire up you browser to get the online Comcast registration screen , but that do not work for we -lrb- we never see that screen -rrb- . it take a couple of call to Comcast -- the first one to someone who have not a clue , and the second one to someone much more knowledgeable -- to get it register . once that be do , it have work without a hitch for about a week .
