Yes, I have what should be the newest Cox DOCSIS 3.1 modem/router device.
A buddy who is "in IT" also suggested that I buy a Google Mesh device that I'd attach to my current modem/router but "disable" the Cox unit's WiFi and then use the Google router and pod devices.
I did finally get the Cox Pod to go online yesterday in our kitchen, and directly one floor above my basement office but its doing nearly nothing to provide a usable signal there, which is where I need it the most.
I guess speeds diminish with each subsequent pod, so I see this as a huge issue if I try to add more, as I'm only getting 300-400Mbps from my gigabit service when I'm 10 feet away from the router as it is. Maybe running ethernet cable is the ultimate solution, as I am hearing that I'll never get gigabit speeds over WiFi.
This is all rather ironic and unfortunate I had a perfectly good setup with my (now unavailable) 300Mbps service and the hard-wired extender which provided consistent 300+ Mbps speeds in my office. I feel like I've been sold swamp land by Cox, as in the end I am now getting a far, far reduced TV package and terrible internet coverage for more $$$.
My city only has Cox or AT&T, and on my street the only AT&T is Uverse, which we had and which drove us to Cox in the first place.
