I buy this modem after my 6.5 year old Terayon die a slow painful death . that be a long story . well , I have have this modem for 2 week so far and it work great . it do run a little warmer than a DOCSIS 2.0 modem -lrb- but not hot -rrb- , but I think it be well worth it . I also keep mine in a well ventilate area , so no worry . I have a mid-tier plan with Cox Communications and this have cure all of my problem . oddly , I see a lot of new people pop up when search for wireless network around I . I assume that I be lose bandwidth to the increase in use over the past year or two . it be clearly the modem . I be to the point prior to this purchase of be unable to do any gaming and netflix streaming for the past two month be a gamble . now , all be well and all of my service be work as well as I would have hope . I have regularly test on speedtest.net , just to see what I be get now . a rough average for I be : 50 mbp down 5 mbp up 30 m Ping however sometimes it be a little higher or lower , for instance yesterday I download a 80mb podcast and it take 8 seconds , so do the math on that . and it work out to about 80 mbp download . so , I do believe that if you have the bandwidth in you local area , future proof with DOCSIS 3.0 lastly , the design of this cable modem be great . it be compact and attractive , even though I have do a good job of hide it . to quote my wife `` its really cute ''
