    your Netgear "modem" is not a modem but a router. Your ISP provided device is a modem/router combo. Connecting these two together without setting your ISP modem/router into bridge mode creates a double NAT which you should avoid

     

    The firmware version of the R8000 can be found either in the app or the Web GUI at http://192.168.1.1

    Your ISP modem/router most likely has a label on it with the device model

Thanks for your respond,

I need of a procedure of how to setup, 

When I set up, it just went very fast and smooth untill I see only one band which is 5Ghz, 

I then down load the nighthawk app then I was be able to see other 2 bands

But then I would lost the internet connection, so I unplug the ethernet cable from the comcast modem and go back to the original setup of comcast, which is their modem/router.

I don't know where to get the info of firmware, my netgear modem is R8000, ac3200 X6

 

Thanks

    I am having hard time to re-connect to http://192.168.0.1 or http://192.168.1.1

    Now I understand the double NAT, I will looking for how to disable the ISP Modem/router then re-connect my NETGEAR R8000 to and set up again

    Another question, now when you disable the 'bridge' from comcast modem/router.. can I switch back if the NETGEAR router set up do not go through?

     

    Thank you

      You should be able to switch back the mode on your ISP modem/router

       

      NETGEAR firmware automatically sets 10.0.0.1 as LAN address if it detects another router is connected to your network, like the ISP device you have. You may try login to http://10.0.0.1

        Thank you so much Microchip8,

        I will try again, but this time I  will disable the comcast modem/router's 'bridge' before reinstall the netgear R8000.

        I will let you  know how it goes.

        Have a happy holliday!
