Re: Are ALL RBR750s defective?

Let's start with:

Who is your ISP and what equipment did they provide? AT&T lightspeed BGW210
What is the current firmware on your Orbi device? Listed above, it is latest and greatest.
What device is your Orbi router connected to? BGW210 from the ORBI box.

 

Let me go through this and report back...


Did you reboot your ISP modem/router, before starting the Orbi router install? Between 10 and 15 times.
Have you changed the network cable connected from the ISP device to your Orbi router? 3 times, every time I get a new system.
Are your satellites wired or wireless? Wireless and they are the only part of the system functioning as intended.
Disable Circle, Armor, Daisy Chaining, Fast Roaming, IPv6 and uncheck 20/40Mhz Coexistence. 
Enable WMM, Implicit BeamForming, Mu-MIMO,
Set Short preamble mode. Save settings, reboot Orbi.
If wired, what cable size was used, as wrong size can cause slow speed.

Modem Combo Units: 
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=deskto
