A:AnswerYes. I just plugged it into my modem, downloaded the Netgear Genie and was able to set it up. You can also download the Genie onto your computer if you connect it to your existing network via Wifi, as that is part of the setup process.
A:AnswerThis is a router, not a modem. For the most part though a DOCSIS 3 modem is a DOCSIS3 modem. You can use the speed on the modem packaging as a guide, or you can call cox and they should be able to give you a list of compatible modem model numbers.
