Orbi rbk50 90% performance drop over 2-3 days, memory leak?
I found another post, it seems there are hundreds of people reporting symptoms where their 300Mbps connection drops to 30Mbps. Completely unacceptable known issue. I updated the firmware but I c...
...some folks reported that it's impacting only the Satellite and not main Orbi itself. If that's the case, please get the debug.htm from the affected Satellites. Here is an example of my healthy Satellites debug info:
Satellite-1:
Basic Infomation CPU Load 17.2577% Memory Usage(Used/Total) 124MB/495MB Flash Usage(Used/Total) 2945MB/4096MB Satellite-2: Basic Infomation CPU Load 22.2222% Memory Usage(Used/Total) 123MB/495MB Flash Usage(Used/Total) 2945MB/4096MB
One factor that could negatively impact throughput/speed is high CPU usage. To monitor Orbi/Satellite CPU usage, please do this:
- Enable telnet via debug.htm page
- telnet into Orbi
- telnet 192.168.1.1
- type this cmd at the telnet window
- top
Repeat the same steps and replace Orbi IP address with IP address of the Satellite you want to monitor. CPU usage should be less 30% and should not anywhere near 100%.
I will give it this last try later today. I hope that's the case! which seems to be the cause based on your description. Then what is the solution?
Has a factory reset and setup from scratch been performed since last update?
What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem 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 is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-routerWhat channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings
Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

It's hard to speculate what the solution is until we can confirm the reason for CPU hog or memory leak. Assuming that's the case, we could kill the offending process by turning off the associated feature if we could identify it. Otherwise, we could roll back to a prior FW version that didn't suffer from this problem.
Hey guys, I've got an update on my side...
I could see when I disconnect my MBP or other device and reconnect it, the RX/TX rate came up to 866Mpbs again.
So, I don't know what happenning on router when I disconnect, but disconnecting/reconnect is better than rebooting the router each 3 or 4 days.
I reseted it to factory, reconfigured all the settings again and this issue still happen.
When I see the problem again, will try the telnet solution above to see CPU/memory activity on RBR.
