I absolutely love this modem . the lead 's be super cool and the design be awesome for how compact it be . I have mine in open air not surround by anything and this modem never heat up it and have stay at the same temp as it first start . speed be amazing also , this modem keep I either at my advertised rate without drop in speed or it even increase it to almost 2x as fast as what I pay for . so far I get this to work with charter high speed call they to activate it and once activate there have be no problem at all . overall for a great Modem to replace you old beat up docsis 2.0 modem and take advantage of the new speed I would highly recommend this modem for a great internet experience . \*\*\* Update 6\/15\/12 \*\*\* : it time for out with the old and in with the new ! Docsis 2.0 modem now will be speed cap since cable network be upgrade to docsis 3.0 . that be why you need this guy ! . not only have it give I up to double my speed but it also give I a constant internet speed . I still highly recommend it !
