      Be sure to speed test with a ethernet connected PC. 

      Use good quality LAN cables. CAT6 is best.

        It is an odd situation.  Here is a summary of what I have experiented in order of what I did.

        • I connected directly to the model using a 5e cable, and was able to pull 400 MBts/sec
        • Then, I connected the R8000 router and connected to one of its LAN ports.  I was able to pull 400 MBts/sec. 
        • Then, I ran a speed tests using the Genie Web-App (192.168.1.1).was only able to pull ~200 MBts/sec.
        • Then, I started WiFi and did a speed test using the Nighthawk app (iPhone).  It also indicated only a ~200 MBt connection.
        • Then, out of curiousity, I connected a older Nighthawk 1700 to a LAN port of the R8000, and I set the 1700 to AP mode. 
        • When I tested using a LAN on the 1700 with a 5e cable, I was able to get 500 Mbt/sec.
        • However, when I tested using the Genie WebApp (192.168.1.1) only ~200
        • Finally, when I turned on the WiFi for the 1700 and did a test with the App on my iPhone, I only got a 200 MBt connects.

        What this tells me.  It appears the LAN ports on the Nighthawk series are configured as passthroughs.  In other words, the internal hardware/softward of the Nighthawk does do anything.  That is why they are able to support such fast connections.  However, as soon as the processors/software is engagued, they act as a 'throttle' on any fast connection.

         

        In case you are wondering, I included screenshots of my settings.
