Suddenly slow WiFi RBR850
Hi
I’m having a weird issue, since i bought the RBS850 and RBS850 before 6 month they were working fine but suddenly since last week the WiFi speed dropped significantly from 500Mb to 180mb without any reason. But the WiFi performance on my other RBS are still performing as they intend with 500Mb download and 300 upload. So my issue is only with RBR (router). When I do the speed test from the App it shows the max as I used to have but not Wi-Fi.
I tried Factory reset (twice) and I tried different WiFi channels but it didn’t solve the issue.
I noticed also my XVR is disconnected from time to time even thou its connected by cable.
my setup:
Firmware Version V4.6.3.16_2.0.51
Asus as Router WiFi is disabled
RBR850 as AP 2.4ghz channel 11, 5ghz channel 36, AX is enabled
2 RBS850
ISP Speed 750Mb download and 300Mb Download

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
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 Auto and 48 on 5Ghz. Or 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?What devices are you using to speed test with?

RBR on the ground floor and RBS on the First Floor, more than 30 feet.
What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors nearby? If so, how many?Tried auto and manual (1,6,11). Neighbors wifi is hard to reach since my house and their house are made of concrete also they use different wifi ch than me.
What devices are you using to speed test with?
I used Wifi and cable by my laptop and my S22 ultra which supports wifi6

I saw that before but cant risk it using an unstable/verified version which might make my case worst.
FYI, as I mentioned previously This happened suddenly without changing the settings and it was working fine for months. and no issue with the RBS850.
Try turning OFF the RBS...and power cycle the RBR.
For that size of home, having the RBS maybe a bit too much wifi. The RBR alone can handle that size of home.
Same issue.
Cable modem service is consistently over 200Mbps.
Internet speed test from RBR850 consistently around 230Mbps.
Connections wired into LAN port are over 200Mbps.
All Wi-Fi connections are throttled to about 20Mbps.
Almost as if there is a configuration in the Orbi that is limiting throughput on WLAN.
Also, it’s very curious how the default 90 day support ran out just before this started to happen. Hmm… don’t pay for extended support and you get throttled?
What Firmware version is currently loaded?

Firmware Version - V4.6.7.13_2.1.9
Comcast Internet using a Motorola MB7621 (DOCSIS 3.0)
- Bridge Mode. Not double NATed Router is getting public IP direct from Comcast.
Speed Test Results:
Mac directly to CM: ~230Mbps
RBR850 onboard speed test: ~230Mbps
Xbox X ethernet to satelite (RBS850) Wi-Fi 6e meshed to RBR850: ~230Mbps
Any Wi-Fi 2.4Ghz or 5gHz connection: ~20Mbps
- iPhones, iPads, Mac, Samsung S21, Windows PC with SpeedTest, Fast, Speakeasy, and Google across all platforms.
Note: FW was upgraded recently after slow throughput noticed. No improvement after upgrade.
I have professional experience with throttling technologies and this behavior matches to something artificially restricting Wi-Fi connections.
