RBR50 slow speeds

Hopefully someone will have some insight on this issue I'm experiencing.

 

When I'm plugged directly into my AT&T modem, I'm getting about 950mbps down and 1050mbps up.  Using the same cables, computers, and the same port on the AT&T modem, when I route the internet connection through the Orbi and plug the computer into the LAN port, I am getting 40mbps down and 100mbps up.  I have verified that all connections are gigabit and for some reason it would seem the Orbi is causing this slowdown.  Any suggestions?

    What FW is currently loaded?
    What is the Mfr and model# of the ISP modem the NG router is connected too?
    Is the Orbi system operating in Router or AP mode?

     

    Modem Combo Units:
    Couple of options,
    1. Configure the modem for transparent bridge 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 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

      Thanks for the quick reply.

       

      I'm running 2.2.1.210

       

       

      Internet connection provided by AT&T's Pace 5268AC.  It was not totally clear on how to bridge the modem, but I do have the Orbi DMZ'd and have always had the WiFi disabled on the AT&T modem.  In other testing, I have tried to put the Orbi in access point mode and let the AT&T device handle DHCP, but there was no speed improvement with that.  Again, this is an issue with wired performance, wireless does seem to follow with similar speed issues, though.

       

      I have noticed that the other wired ports on the AT&T modem do run considerably slower when the Orbi is wired in as well.  My next step will probably be to run a factory reset on the Orbi to see if there is any difference.

        See what the reset does. 

         

        I've seen others post about this particular modem and the Orbi. Seesm to not like each other. AP mode should work well if you let the modem be the router. 

         

        Ensure LAN cabling is good. CAT6 is recommended. 

         

        Try disabling the following and see:
        MIMO, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

        If you updated to recent FW v.210, try enabling Daisy Chain. Some have mentioned that this seems to be working in reverse order, enabling means disabled actually.
