Backhaul at 2.4 = low bandwidth
Hello,
I have an Orbi RBk50 and 1 satellite since beginning of december.
Everything was working flawless (300Mbps everywhere), but today, I had a huge bandwidth drop off.
Every devices connected to the satellite had 05-15 Mbps bandwith.
After some research, I did a Telnet on the router and here what I got :
Backhaul connectype : 2.4 Ghz
Bachaul RSSI : -62
Backhaul phytxrate : 96
Backhaul phytxrate : 86
The synced satellite connection shows as "Poor" in the web interface
I rebooted the satellite and then I got :
Backhaul connectype : 5 Ghz
Bachaul RSSI : -63
Backhaul phytxrate : 1300
Backhaul phytxrate : 1300
The synced satellite connection shows as "Good" in the web interface, and bandwith was like usual around 300 Mbps
Then half an hour later, again, the satellite switched to 2.4 Ghz with very poor bandwith. I couldn't work anymore.
My FW is v2.5.2.4
The satellite is 30 feet away from the router.
I changed the chanel to
Automatic > 1 on 2.4Ghz
chanel 48 in 5Ghz
I acivated Beamforming
Since then I've been watching with some anxiety if the router won't switch to 2.4Ghz.
What can I do to avoid this ? I don't really care if it switch to 5Ghz to 2.4 Ghz as long as I don't have a huge bandwith loss...
Thank you very much for help.

Re: Backhaul at 2.4 = low bandwidth
The construction of your house could be attenuating the signals so that 30 ft distance may be too much at your installation. Try moving the satellite closer or at a different room, reset it and have it find the router fresh (like you have tried before).
Also, post your firmware version. It is unlikely that you have a very old firmware on such a new system.. but might as well check. Keep in mind that "improved backhaul" isn't mentioned in the updates release notes, it is an assumption that newer firmware will improve the performance.
The good thing is that your system is new, and you can try the latest firmware. You are in the warranty period or could even return the device to the seller if you "brick" your system with a manual firmware update.

Re: Backhaul at 2.4 = low bandwidth
Has a factory reset and setup from scratch been performed since last FW update?

Re: Backhaul at 2.4 = low bandwidth
Hello,
Thank you for your answers.
My firmware is V2.5.2.4, I think it's the latest version.
I'm in an appartement and everything during 3 weeks without any problem...
I didn't do any FW update since I have it. When I check the FW it says I have the lastest version : V2.5.2.4

Good work to find the telnet command to display the backhaul status. Yes, you care very much if the backhaul switches to 2.4G because the maximum throughput on 2.4G is 400mb, and it is shared with the "user side" 2.4G devices since there is only one 2.4G radio.
I do not see "what can change" when 5G backhaul has been working for some time. The walls were there when the connection was "Good". Walls have no moved. My fear is that something has disrupted the backhaul signal. (Weather/military radars can do that.) Do you have any tools that will show what frequency the 5G backhaul is on? (It will appear as a WiFi system with hidden SSID.) If the switch happens again, I would want to see if that hidden WiFi remains alive or has disappeared.
It is so seldom that someone comes on the forum with time left on Netgear's 90 days of "complimentary support". If this happens even one more time, I would be on the phone asking for a warranty replacement.

On Android, my personal favorite is WiFi Analyzer by Kevin Yuan. I also have one by Abdelrahman M. Sid. (there are dozens more) For Windows WiFiInfoView from Nirsoft. I believe iOS does not allow developers access to the WiFi stack to create apps like these.

Re: Backhaul at 2.4 = low bandwidth
Ok I installed a wifi analyser and I did some test :
When everything were Ok in 2Ghz this morning :
Freebox-435267 is my box
Then 5 Ghz
And this afternoon it started again
And now, with the Wifi analyser I have this :
I have 2 times my Box (Freebox-435267)
In 2 Ghz :
And in 5 Ghz, same thing :
So I don't really understand whats going on...

"Inline" images do not appear in posts until one of the forum moderators approves them. considering how many forums they look at, this can take hours (or days?) Images attached (The "Browse" button in the lower left) are immediately available.

Re: Backhaul at 2.4 = low bandwidth
Yes, I believe several pictures can be attached to one message.
It appears to me that the backhaul channel may be impacted by radar systems. Check channel 106 for Europe in this chart:
https://en.wikipedia.org/wiki/List_of_WLAN_channels
There is a long post about radar and 5G channels:
https://community.netgear.com/t5/Orbi/5Ghz-channels/td-p/1538610
(reading over it illustrates how little CrimpOn knows about networking)
Two points stand out:
- If there is only one satellite, Daisy Chain should NOT be Enabled.
(Advanced Tab, Advanced Settings, Advanced Wireless Settings, toward the bottom of the screen) - There is a way using telnet to see if the backhaul channel if being affected by radar.
Message #23.
I have tried this on my Orbi and "got nothing", which leads me to conclude (a) the instrutions are incorrect, or (b) my Orbi has never changed backhaul channels because of radar.

Thank you for your help.
Daisy chain is disabled, and I tried the comand but I have no such file or directory...

Re: Backhaul at 2.4 = low bandwidth
It might be time to contact Netgear and take advantage of that 90 days of "complimentary support". Doubt that calling from (France? Belgium?) is practical. I believe the web page when systems are registered has a link to "Contact Support". Maybe they support a Chat session?
Orbi WiFi switching to 2.4G backhaul is supposed to be a "last ditch, desperation" way to keep the system alive, NOT a part of regular operation. When it syncs at 5G and runs for hours before suddenly switching to 2.4G, something is wrong. If this can't be fixed, the system needs to go back.

Re: Backhaul at 2.4 = low bandwidth
I forgot to mention, I set the strenght signal 5Ghz and 2.4Ghhz to 50% ? Can it be a track ? Even if it works during 3 weeks without any problem ?

The "Transmit Power" setting affects only the "user facing" 2.4G and 5G radios. The backhaul radio operates at full power (at least the user has no control over it).

Re: Backhaul at 2.4 = low bandwidth
Last question, in the event that I put an 15 meters rj45 cable for example, between my orbi router and my orbi satellite, does it will bypass the backhaul radio ? The router and the satellite will communicate with the cable instead of the radio ? I don't know if I'm clear..
Because I doubt it's a hardware problem, because if it was hardware, it wouldn't work 3 weeks ans some times all day without problem. I lean more for an interference problem

Re: Backhaul at 2.4 = low bandwidth
Yes, wired connection between the router and the satellite replaces the WiFi backhaul connection between them
The advice here is to update the firmware, set up the satellite with wireless backhaul and then switch over to wired backhaul.

The backhaul wifi ratio is still active when the RBS is ethernet connected.

OK thank you. Does it mean you can have this kind of drop off even wired ?

Re: Backhaul at 2.4 = low bandwidth
No, it shouldn't. Would be less unless there was near by wifi interferences.
