Netgear Nighthawk XR500 slow speeds

So I have a 1gig ISP package. When It tests the speed , It only comes up with 523.34mbps down and 254.87 up.. My package is for 1gig down and 250 up... I have speed tested the internet straight from the adtran fiber optic device(modem) to a laptop and have gotten 900+ mbps down and 240-50 up... what could be the issue here??

      Could you first of all make sure QoS is set to maximise your bandwidth speeds: http://support.netduma.com/support/solutions/articles/16000076586-dumaos-optimal-settings-guide-speeds

       

      Then are you able to set you modem to bridge mode or modem mode? It's possible that it's struggling to pass full speeds onto your router.

       

      If that is not possible, can you check the CPU graph on the XR500 (found in System Information). Does it get fully maxed out when you run a speedtest?

        So i was doing a speedtest on my laptop using the ethernet cable i normally hook up to my ps4 pro.. amd i was getting 800+ mbps download and my 250up. The thing im wondering is why the speedtest the duma interface does is soo low? When you do the setup and checks for internet connection.. the interface then tests the speed to automatically give you values for the download and upload speeds in the qos settings.. thats where i received the 5xx download speed.. thats 500mbps off what my service calls for.. my laptop clearly read over 500mbps on a speedtest.net.. now do i adjust the values manually to a higher number for my download? I would assume the router should do that on its own.. what sense would there be for anyone to plug in a faster download speed than what they actually pay for. Or do i just leave the values the router plugged in automatically for my speeds??
