Orbi AX4200 WiFi 6 Router (RBR750) doesn't detect internet connection

My router isn't detecting the internet connection from my modem. However, I know the internet connection is good because I can use an ethernet cable to connect my PC to the modem and have access to the internet. I've tried all manner of reboots and factory resets for both the modem and the router to no avail. I feel like I've exhausted the options I'm aware of using. Does anyone have another suggestion to resolve this issue?

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

     

    Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
    Be sure to restart your network in this sequence:
    Turn off and unplug modem.
    Turn off router and computers.
    Plug in and turn on modem. Wait 2 minutes for it to connect.
    Turn on the router and wait 2 minutes for it to connect.
    Turn on computers and rest of network.

      Firmware version: 4.6.7.13

      ARRIS SB6190 modem (not provided by ISP [Comcast] but it is compatible with Comcast's signal)

      Yes, the power off/on cycling has been completed since the last update.

      I followed your instructions and the router cannot make an internet connection.

      My computer is only functional with an ethernet connection from the modem.

        What's the connection rate show on the Connection Status for the WAN port on the RBRs web page under Advanced Tab? 

        What is the CAT# LAN cable between the modem and RBR? CAT6 is recommended.

         

        Also, be aware that the SB6190 has a vulnerability and is not recommended.
