I be look to switch to Charter Cable Internet service , so I price it out online and find that they charge $ 7 per month to rent a cable modem . so , I check what type of cable modem be require and it say DOCSYS 3.0 . hit amazon.com with that search and find this . so , I call Charter to hook I up with service , tell they I would purchase my own modem , and immediately ordererd this . get it the next day , unpackaged , hook up in under 10 minute , call Charter with the MAC address and I have Internet service with speed upward of 60mbp down \/ 4mbp up all in less than 20 minute after open the box . the spec say it will handle up to 160mbp , so when Charter get better , it should grow with they . have not have to reboot the modem a single time , like in the good ole day . the only improvement I can think of would be the modem be able to hook itself up .
