So trying to hook up Ethernet port two. No go. Login to modem admin and look under hardware>LAN and it says that port 2 is inactive then has a check box to dedicate to home security (but it will no longer show on the home network). Try 3 techs who send a "hit" to the modem to activate the port. Finally get escalated to a tech who says I dont think it can be activated. So why in the name of all that is holy does Cox proudly advertise the below on the site (straight up false advertising). Anyone able to get both Ethernet LAN ports working??? Considering getting a Netgear CM1200 and just running 2 WiFi routers at either end of the house which would be hardwired into the Netgear as that model is not WiFi.

The keyword is "switch" in the statement. The 2 ports on your CGM4141 is essentially a switch on your personal, private, in-home network.
When you connect a modem to the Cox network, Cox will assign only 1 public IP address to 1 port on your residential modem. It's usually Port-1. You can connect whatever you want to Port-1 for that public address: PC, router, game-console, TV. Whatever you connect to Port-1 (public address) will have Internet access.
If you connect a router to Port-1, the router will have Internet access. If you in-turn connect a laptop to the router, the router will then assign a private IP address to the laptop and then the laptop will have Internet access. Repeat as necessary for more private addresses on your private network.
Port-2 is a switch on your private network. It's a 1-port switch. Whatever you have connected to Port-1 can communicate with Port-2...privately...because it's on the same subnet. However, only the device(s) connected to Port-1 will have Internet access.
The "advanced routing capability" in the same statement probably means Port-2 has high-speed routing capabilities (Layer-3) but without Internet (WAN) connectivity. Cox will have to clarify that snippet.
If you want Cox to assign 2 public IP addresses to a modem with 2 WAN ports, you'd probably pay extra or require a Business account...and possibly a different modem.
