There is one a step up, Model # 6183 which has 16 channels for downloads and claims to be faster. However, unless you are in San Francisco or somewhere with crazy fast internet, the modem is rated for more than you can get. Bottom line, save the $ and get the one from the link above. I go through Cox and it's approved for them and most cable companies. I just upgraded to a Docsis 3.0 Modem so I did all the research. I stayed with my old router. Don't get the wifi router and all in one modem combo...they are garbage. Don't rent either, you will have it paid for in a year.
