does it work with cox?
I am looking for a modem that will work with my internet service provider which is cox
N600 works with COX. But device don't expect very good performance with N600. If you are really concerned about dazzling speed and range. I recommend to go with separate modem and a separate router. Like Arris 6141 ( something like this ) modem and router like Apple airport. Or if you still looking for integrated device Netgear AC1750 should be your best bet.
