I recently switch from dsl to high speed internet , basically from CenturyLink to Charter . while talk with the Charter rep , I manage to find the listing of all the modem that they lease out and come across this beauty . I decline to lease this modem from they , as they want $ 7 a month , so you basically buy two of these modem over the course of a two year contract . so this be a no-brainer and I buy it . the technician that come out be surprise to see this modem while hook everything up as the DOCSIS 2.0 modem can not handle very high speed , and this be where the DOCSIS 3.0 come in . I be download speed up to 50 mbp now . I just have to change my wireless router setting to DHCP and the DOCSIS 3.0 take over and I be on my way to the high speed superhighway ! I do not have to go into the modem GUI to mess with any setting either . so basically I hook this up from the coax cable in the wall , feed a cat6 cable from it to my wireless dual band router , set my router to DHCP , and everything on my network instantly have connection . its worth the money if you be look to get speed of over 30mbp to you home and lease one from the cable company be just a waste of money in my opinion .
