Slow LAN speeds on RBR850, half of what I got on my RBR50
My RBR50 finally gave up the ghost. The firmware was corrupt and I could not figure out how to telnet the firmware to it any longer. So...I replaced my system with an RBR850 and two satellites. The wifi is faster than what we experienced before and seems to be more seamless. However, I used to get 950ish Mb/s to my desktop in my office, and now I get about half that speed. If I swing the cable for my office directly to the cable modem, I am back in the 950 range as expected. Speedtests run from the Orbi management screen show speeds around 1400+ Mb/s. Any ideas on what would be causing such a drop in speed from an RBR50 to an RBR850?

The WAN (Internet) port on the RBR850 router is a 2.5GB Ethernet port. When the Orbi Speed Test reports 1.4GB, that is an indication that the link between the cable modem and the router is running at 1.4GB.
My guess is that the computer has an 'ordinary' Gigabit Ethernet adapter. That means when the computer is connected to anything, the maximum Ethernet link that can be negotiated is 1GB. In practice, the maximum throughput on a 1GB Ethernet link is slightly less than a full gigabit because of the overhead in Ethernet transmission. 950ish is pretty typical.
I agree entirely, when
the modem is delivering 1.4G to the router
the Orbi router port is 1G
the computer port is 1G
Then the measured speed at the computer should be slightly under 1G ("950ish") A speed of "half that" is unacceptable. I can think of nothing that would explain how an 850 would produce less speed than a 50. None.
Fortunately, a new purchase comes with 90 days of "complimentary support" (as opposed to, "you bought it. YOU figure out how to make it work.") How about registering the new system with Netgear at my.netgear.com and have them explain this?

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.
How many RBS are deployed? What is the size of your home? Sq Ft? What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS🛰️ to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 🛰
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz. Any Wifi Neighbors near by? If so, how many?

Something that can possibly help is to ensure that the Ethernet Network Adapter is set to link speed to 1Gigabit. It might be set to Auto Negotiation. Please let us know if this helps.
You can change the link speed from Auto Negotiation to 1000Mbp/s by going to device manager. Then click on Network adapters and double click you ethernet adapter. Then go to advanced tab and click link speed or speed/duplex.

I would be very interred to hear what L2 has to say. I experienced a very similar condition ever since I upgraded to Windows 11 22H2. When I revert back to Windows 11 22H1, no problem. My NIC is set to 1Gbs - no auto negotiation

Hi Robert,
Microsoft was very engaging on this and no traces I provides indicted problems on their end so they suggested I try another manufacturers mesh router again so I borrowed an ASUS Zen WiFi Pro AXE11000 router and had full contracted ISP speed. No problem. Wired and wireless. Bought a RBRE960 with 1 satellite and problem solved on my end.
Netgear had sent me a replacement RBR850 which made no difference but I wasn’t going to invest any more debug time. Problem may be is a firmware bug in RBR850 code.

In Houston. Took router to another site and had same issue on any PC that was Windows 11 22H2. PC’s with any version lower did not have that performance problem. Unable to try lower RBR firmware without auto update occurring. No longer have the RBR850.
