Nighthawk compatibility with Xfinity xFi Advanced Gateway

Xfinity just sent me a replacement modem/router named xFi Advanced Gateway. Is this device compatible with my Nighthawk AC 1900 router? Is there any adaptation I need to make to ensure that if I set up the Advanced Gateway, it will work with my Nighthawk router? 

  • If possible, you should put the Xfinity modem/router in bridge mode and let the Nighthawk be your main router. Otherwise, you'll be stuck in a double NAT

         To replace _what_, exactly?

         Does your (unspecified) "Nighthawk AC 1900 router" have a model
      number?  Look for "Model" on the product label.

         This, presumably, has nothing to do with anything?

       

         How, exactly, were you using your (unspecified) "Nighthawk AC 1900
      router" with whatever you had before?

         Probably, but that might depend on what you're trying to do.  Why,
      exactly, do you want to use your (unspecified) "Nighthawk AC 1900
      router" with the new xFi unit?

       


      > [...] Otherwise, [...]

       

         Most likely, you want one router, not more, so you'd need to
      configure one of these devices differently, but there's more than one
      way to do that.  You could, perhaps, for example, leave the xFI as-is,
      and configure your (unspecified) "Nighthawk AC 1900 router" as a
      wireless access point.  But that might depend on what, exactly, your
      (unspecified) "Nighthawk AC 1900 router" actually is, and why you're
      using it at all.

        1) The xFi Advanced Gateway modem/router combo is a replacement for an older xfinity modem router combo, Arris TG 1682G

        2) Nighthawk model number was posted previously in the Model box above: A7000

        3) The first reply to my post reminded me that I had put the Arris modem/router into bridge mode. I doubt the instructions explain how to do this, so I will contact Xfinity support if I decide to do that.

        4) I am assuming that the xFi Advanced Gateway modem/router is faster than the Arris which is four to five years old. Faster internet was suppose to be one of the benefits of my new Xfinity plan.

        5) I chose to keep the Netgear Nighthawk A7000 when the Arris was delivered because the local Xfinity store agent told me that the Nighthawk was a better router than the Arris device.

        6) Overall, my reason to keep using the Netgear Nighthawk A7000 was that I purchased it in 2014 when I began to convert to a number of smart home devices, e.g., Lyric thermostat, Alexia, Kasa plugs and switches, Ring doorbell, Behmor smart coffeemaker. At the time, I knew the Nighthawk A7000 could handle smart home devices, but I had no info from Xfinity support advising that the Arris could do that.

         

        If this reply gives you more information, please advise me what steps to take.

        Thx.

      Thanks -- this is helpful. I knew there was a special setup used when the last xfinity modem/router was delivered, but I couldn't recall what it was.
