Netgear r7800 - not getting gigabit via router but it is possible via the access point

    Since your Arris device is locked down and providing routing functions, you might consider configuring both R7800s as access points.

How are you speed testing with the main R7800? 
How is the Basic and Advanced Wireless settings configured. 


Wired speed tests you shoul see near or just over 900Mpbs on the down.

Wireless, depending on wifi device design and support usually maxes out at around 300-500Mpbs on 5Ghz AC with 80Mhz channel width. If you enable the 160Mhz channel with to support 1733Mpbs on 5Ghz AC and IF your client devices also support 160Mhz, then you could see near 900Mbps and over on 5Ghz AC.

 

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 disabling the following and see:
Armor, Circle, Traffic Meter.

 

The 2nd R7800 in AP would would be correct since it's ethernet connected to the 1st R7800 at 1000Mpbs.

    Speedtesting is done via the Nighthawk app (Router and Accesspoint)

    I experience the same cap via Wifi AC on the router (between about 600Mb. It can reach 650Mb briefly but then it 'maxes out' - it seems and drops to 500Mb).

    Speedtesting via Wifi AC on the AP is about 750-800Mb (Standing close to it). Which is probably pretty good for wifi.

     

    Router uses 160mhz

    AP uses 80mhz now (because of DFS issue). The speedtest was done with 160 mhz.

     

    Cablemodem

    Arris TG3492LG-ZG

    Ziggo is an Internet provider (cable) in the Netherlands (1000 down, 50 up)

     

    Firmware versions

    Router and accesspoint: V1.0.2.92

     

    Armor, Circle, Traffic Meter etc. were and are not is use.

      2,4 up to 800 (ch -6)

      5 up to 1733 (ch - 48)

       

      Enable Implicit BEAMFORMING - Boosts WiFi speed, reliability, & range for all mobile devices - V
      Enable MU-MIMO - V
      Enable HT160 - V

       

      WAN

      Disable IGMP Proxying - V

      Disable SIP ALG - V

      Nat filtering open (was secured - no difference in speed)

      Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
      https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
      Couple of options,
      1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
      2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
      3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

      Try option #2 first...Thought I believe Arris supports option #1.

        Option 2 is the current situation.

         

        Option 1 is an option but i cannot do it myself. Ziggo has give the modem its own interface and that option isn't available.

         

        What I do not understand is that the AP can reach up to 950 via the router and modem, but the router cannot and needs the modem to be in bridge mode.
