recently , we provider -lrb- Mediacom -rrb- introduce 50meg internet in we area , which require the use of a Docsis 3.0 modem . I purchase this after read the review , and be very impressed with the result . as I upgrade both my cable modem and internet at the same time , I can not attribute gain in internet speed to one or another , but I be consistently pull 47meg down\/5meg up on speedtest.net , which be great speed in my book ... the modem do what it should ... connect I to the web , and it seem to do a very nice job of it after about 3 week . have never have a issue that i have have to reboot it -lrb- problem frequent with my last modem -rrb- and just continue to work . one word of advice be to make sure to keep the box , as it have the ID you will need when you call you cable company to activate you modem once you hook it up . Might be somewhere on the modem as well , but find it on the box be convenient . overall , very good buy .
