HELP! Slow WiFi on RBR850
Desperate for some help, this system is driving me mad!
I've got the RBK853 - AX6000 Router and 2 Satellites
The router is plugged into the service provider modem with a Cat 8 cable. On the Orbi app it's saying 920MB download and 110MB upload. All good so far!
When I run a speed test (using FAST.COM) right next to the router I'm not seeing anything above about 560MB. I'm being told I should see about 90% of what I get through ethernet, which would be about 830MB.
I've tried the standard adjustment of removing 20/40MHz coexistence, setting the 2.4GHz and 5GHz channels and putting it on 1492 but none of it improves the speed.
Would really appreciate any feedback or experience anbody has on how to improve 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?What devices are you using to speed test with near the RBR?
What are speed results with a wired ethernet connected PC at the RBR using Ooklas installable speed test app?
Hi FURRYe38
Thanks for responding.
Firmware is V3.2.18.1
The ISP modem is a BT Smart Hub 2 (UK product) - with WiFi turned off
WiFi tested on a MacBook Pro 15" 2019 and iPhone 12 Pro Max
Ethernet tested on a MacBook Pro 13" 2010
WiFi results on Ookla Speetest is 620MB on both devices standing right next to the Orbi router
Wired ethernet speed is 913MB on the old MacBook
What connection rates are you seeing on the MBP 2019? Select Option and right click on the wifi icon on the top tool bar to reveal connection rate info. If your 2019 Mac Book doesn't have AX mode support, then max connetion rate you'l ever seen between the MBP and Orbi is 1300Mpbs on 5Ghz AC.
My 12Max iphone has seen near 700Mpbs however mostly hangs around 500-600Mpbs. My MBP 2018 sees around 700Mpbs at close range. 500-600Mpbs mostly. This is typical for the AC mode support on 5Ghz. You wont' see much near 900Mpbs on wifi like on wired ethernet. Unless you have AX mode supporting devices along with 3x3 or 4x4 MIMO antenna support. My ASUS GT-11000 in client wireless bridge mode gets 900Mpbs+ while connected to the RBR. Close distance.

Assuming you are using a 2 srteam AX capable wireless device the maximum sync rate will be 1201 mbps and your syncing at that rate.
Historically my impression is that (on a good day and not all days are good) I get throughput around two thirds of the wireless sync rate but, if yor lucky, you might get three quarters of it. That's just the way it is due to the various protocol overheads involved in both wireless and IP communications.
Given that you seem to be able to get around 920mbps that should relate to about 610-690mbps. If you get getter than that then the wireless technology is improving which it should be.
What your seeing isn't that far from what I'd expect but 90% (aka. 820 or so) is a bit optimistic IMO.
So there may be room for improvemnt here but I'm not so sure it will be as much as you think.
Testing with a 4 stream wireless device (not many desktop or mobile devices around with that) then you would expect to be able to get the maximum possible available throughput.

I hear what you're saying, but it doesn't match up with what Netgear and other users are telling me.
Actually my analysis was flawed, I assumed your device wireless was syncing at 1201mbps but used 900mbps to calculate expected throughput.
If you use 1201 for what I'm describing you get 800-900mpbs so the speed is a bit slow.
It's worth checking what rate the device is actually syncing at, that will make a difference and whether the trafic is being routed via a satelite (unfortunately I'm not aware of a way to check the sync rate of a satelite) or not since that will make a difference too.
