Orbi RBK752 Speeds
Hi all, I recently picked up an Orbi RBK 752 AX4200 kit which has the RBR750 and RBS750. My ISP is AT&T Fiber with a 1 Gbps plan. After setting up the Orbi kit, maximum wifi speeds I can get is around 350 Mbps. This is over wifi 5 Ghz band to the main router (RBR750). I also get the same speeds with my PC which is hardwired into the satellite node (RBS750). When I do the speed test on the Orbi app (between main router and modem), I'm seeing around 600 Mbps down and 900 Mbps up. When I connect directly into the AT&T modem, I see around 800 Mbps down.
When I did the initial install, there was a firmware update which was installed. However in the process of troubleshooting my speeds, I've done a factory reset, enabled WMM, disabled security, etc. However speeds remain the same. Anything else I can try?
Pretty disappointed at the moment since my previous set-up with an Asus RT-86U was almost the same speeds but at 1/3rd the price. I'll continue to troubleshoot for a few days before I return this set-up.

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?What are wired speed results with a PC and using Ooklas installable speed test app connected at the RBR?
What wireless devices are you using to speed test with?
Firmware is currently v3.2.15.25.
AT&T Modem is a Pace 5268AC.
Wired speeds at the RBR is around 500 Mbps down.
I've tested wireless on:
- 2019 Macbook Pro with Airport Extreme network card- Two different PCs both equipped with a Wifi 6 AX3000 PCI-E wireless card.

You can try upgrading to v32 and see. What I'm using. ALso using default CTS value of 64.
AT&T Modem is a Pace 5268AC.
What node is this modem working on? Router or Bridge? Bridge would be recommended.
This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-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=desktopWired speeds at the RBR is around 500 Mbps down.

At what distance are these devices from the RBR?
Realize that the difference between your old Asus and the Orbi is it is a mesh wireless (broader coverage in your home) and AX (wifi 6, but only for such devices). Therefore if you use a wireless wifi 6 device, like an iPhone 11 Pro, then you should be seeing faster speed. In my experience even these devices see 600s or maybe 700s on my RBR850, but there is always other wireless communication overhead which will limit it to less than what you see with a wired connection.
Other non-wifi-6 wireless devices will not see much difference (though my non-wifi-6 laptop did see a little better speeds). If you're cost conscious then waiting until you have mostly wifi-6 devices before upgrading to AX is probably a better approach.
For best accuracy, make sure you're using something like the speedtest.net app or website to measure speeds and not the Orbi app or web portal measurement.
Yeah I wasn't expecting much of an improvement on my wifi 5 devices. But I do have two PCs equipped with Wifi 6 cards and another PC which is hardwired into the satellite node. Speeds are still disappointing right now...
> Wired speeds at the RBR is around 500 Mbps down.
We can focus on this issue first (before worrying about why your wireless clients are also seeing slower speeds). Is your Pace 5268AC in bridge mode, i.e., the WAN IP address shown on orbilogin.com is the same as seen at https://canyouseeme.org/? If not then you have Double NAT and putting your modem in bridge mode may increase wired speeds.
