Asus MaximusVIII Hero w/ onboard ethernet (Intel I219-V controller, Driver Ver. 12.13.17.7)
Extra NIC, Realtek PCIe GbE controller, Driver Ver. 9.1.410.2015
Gigabit Ethernet card.

Motorola cable modem model #MB7621-10

AT&T Arris DSL modem and WiFi router Model #BGW210-700
Windows 10 x64 Home
OK, right now, I have my cable modem connected to my motherboard ethernet, and the connection to the internet is solid. But I've had to disable both controllers on the NIC (rather than pulling the cable). I have the same problem regardless of which NIC port I use. There seems to be some sort of conflict between the two connections that Windows cannot resolve. Once it tries to configure the second ethernet connection, I lose internet in both. It doesn't seem to matter which one I set up first. And the only way to recover is to unplug the ethernet cable from one modem and reset the other one (or disable a controller for one modem, then reset the other modem). Both are set to automatic DHCP. This problem persists regardless of which port I plug which modem into. So I know that both modems and all three ethernet controllers are good. Individually, they all work in any modem/port combination I want. But together, the two connections break each other.
Once we get into manually configuring things, I'm at a complete loss. So please be very specific when telling me what information to plug into each data field and where I can find each field. For instance, let me know if you mean to edit fields in the "internet and settings" page, or through Control panel, or in the Device Manager (properties). They sure don't make it easy to find everything anymore. Also, if you or I need some information, please let me know where to find it.
I sure hope someone can help me get these two connections to play nice with each other.
TIA.
