Cox Hot Spot running off my modem

Thanks - but this does not solve COX using my router as a hotspot.  All of these security measures had already been taken.    My network was secure.  This hotspot is something built into the router supplied by COX that I rent.   I was never told of this.  When I saw this open access hotspot - I assumed it was a neighbor.  I had no idea it was my router.   Cox is supplying this to strangers (in my case the homeless person living outside my house that the police will do nothing about) using my monthly fees and my electricity payments. I imagine one day they will be a class action lawsuit against this - it is not right.

In this thread we're discussing Cox-provided Panoramic WiFi equipment, whereas your support link gives advice to customers who own and manage their own equipment.

Thankfully the modem/router rentals take this security responsibility out of our hands and allows Cox to manage it.

If you follow the news you would see that customer-owned routers are a weak link and very likely to be compromised, joined to botnets, and abused by threat actors, and the owners will never find out because of poor monitoring and logging.

Cox's hotspot service is a logical idea because most customers' connections have tons of bandwidth and resources to spare. Why not rent out that excess capacity to neighbors?

Whose bandwidth does it use then? If a consumer router offers a hotspot then it will necessarily use the cable connection for connectivity. Unless Cox has devised an ingenious mesh network connecting all their hotspots wirelessly, which seems out of character.

Data usage can be measured separately, indeed. VLANs can segregate frames and packets for security and privacy, yes. But at the end of the day, you've got one box serving many masters, and resources such as memory, CPU, backplane, and DOCSIS channels are shared with your "guests" or parasites.
