Nighthawk X6 Smart Wi-Fi Router (R8000) - AC3200 - much slower than modem

I have 600 mbps upload/download speed fiber optic service. 

When i connect a PC directly to the modem I get >600mbps service.   

When I connect the modem to my router then hard wire to the router I get < 200 mbps.

I have:

  • CAT6 cables connecting everything.
  • latest firmware.
  • disabled Access control, QoS and no parental controls.
  • Rebooted everything 

What should be my next troubleshooting step be?

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

     

    Try a factory reset and setup from scratch along with powering OFF the ISP modem for 30 seconds then back ON. 

    After the router is set back up with a web browser and wired PC, run a speed test using Ooklas installable speed test app. 

    Don't enable any Access Controls, Armor, SPC or Traffic Meter. These will degrade the speed results.
