Only getting ~400Mbps down on 1.2Gbps service with CM1150V Cable Modem and Nighthawk AC2600 (R7450)

Thanks for the reply. I'll try a direct-wired speedtest tonight to confirm the Modem isn't the issue.
The WAN port is definately a bottle neck for over 1Gbps, but I should be able to get more than 400Mbps over it. I expected at least 800-900Mbps since this is typically what the videos I've seen on YouTube are getting for Gbit Cable Modem service ising the ISP-provided modem. This is less than 1/2 what I should be getting, but all the hardware seems to be condigured properly.
I've got to be missing something, but I have no idea what it could be.

Id do a full on factory reset and setup the router from scratch. Power OFF the modem for 1 minute then back on. Do not enable any additonial features like QoS, Access Controls, Armor, Traffic Meter or Parental controls. Test with a wired PC connected to the router only. Don't have any other devices connected and use Ooklas speed test app to test the speed. I found that the onboard speed test on the routers web page may not report accurate results on 7 and 8 series routers.
See what speeds you get after a reset...
