Wow - Cox just doesn't apparently know how to run a network. Or customer service.
I've just moved from my old house with Gigabit Fios. I decided, despite the paltry upload speeds, to get gigabit at my new place. I was disappointed when I found out that the neighborhood I was moving into, despite it being denser, did not have FiOS.
Several calls to customer service later, multiple resets, and it just starts working. The only information that I can find about it is that there are issues with MAC address binding. But of course, not information provided by Cox, just a forum on Reddit. Super frustrating. But glad that we have rain in what was our Internet desert.
