RBR850 satellite 5ghz automatically disabled

[Kunson]

Hello there.

I purchased orbi rb854 suite and setup as router mode with PPPOE ISP. Three satellites use ethernet connect (use cisco switch). I used the network almost month occur few problems can't be resolve even upgrade to latest firmware (v4.6.7.5)

problem 1: use computer (side of one satellite) ping to orbi main router delpy is not stable. Mostly deplay is 2-9ms but every minute occur 100-300ms and turn back to 2-9ms.

problem 2: all clients in area lost connection. showing dhcp no IP (phones and mac computer). in this time login into this area satellite show 2.5ghz and 5ghz network disabled.

model version: orbi RB854 

firmware: v4.6.7.5.

wifi-users: iphone13promax; cameras; macs.

If your using v5 FW and have done a full factory reset on the RBR and RBS and the RBS continues to disable the wifi radio when it's ethernet connected, it would be a HW problem. Mine have been ethernet connected since I applied v5 FW and no radios are disabled. 

NG support needs to look into this one RBS.

What is the model# of the ethernet switch in the configuration?

Is this switch connected to the RBR? https://kb.netgear.com/000051205/What-is-Ethernet-backhaul-and-how-do-I-set-it-up-on-my-Orbi-WiFi-Sy... 📡

What Cat# LAN cable is being used? CAT6 is recommended.

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. Even if RBS are ethernet connected.

Has a factory reset and setup from scratch been performed since last FW update?

[Kunson]

Yes. I did factory reset many times and tried resync. cannot resolve this problem.

Thanks for your reply 

My home use CAT6 Lan cable.

And my home have three rooms and each room use one satellite with wired ethernet connect to main orbi.

My home total almost 1200 Sq. one room 277Sq.

So the problem is too much RBS on my house?

Thanks.

[Kunson]

My satellites between almost 20~25 ft to each one..

[FURRYe38]

For 1200 sq ft, the RBR alone would be enough. Maybe 1 RBS set out at 30 feet. 

I'd turn OFF all RBS and test with just the RBR alone. If you need to add a RBS, find a good  remote location out at 30 feet. If the distance can't be at 30 feet, you can turn down the power output on the RBR from 100% to say 50% and this would help with a bit too much signal strength between the RBR and RBS being too close. 

[Kunson]

Thanks for your advice. 

I just tried just one RBR and one satellites far out 30 ft. it problem still existed. 

And I want keep my rooms have enough RSSI for low latency.

Do we have any other solutions?

[FURRYe38]

If you connect the RBS to the back of the RBR via ethernet while in same room as the RBR, does the 5Ghz get disabled still? 

[Kunson]

Yes.

RBS always getting disabled 5ghz and 2.5ghz with unknown reason.

[FURRYe38]

You might give this a try on the RBS first the RBR lastly, then see if the RBS syncs correctly with 5Ghz enabled while ethernet connected. https://community.netgear.com/t5/Orbi-WiFi-6-AX-and-WiFi-6E-AXE/New-RBR850-RBS850-Firmware-Version-v...

[Kunson]

I've trired many times with on RBS firstly and then on RBK let it fully synced with configs and RBSs show blue IDE..

But still not resolve problem.

[FURRYe38]

Thats with the v5 FW applied and if so, did you factory reset the RBS and RBR and setup from scratch after the FW was updated? 

[Kunson]

Hello.

I've tired many times with factory reset after upgrade firmware.

[FURRYe38]

I would contact NG support and ask for help and information regarding this. The 1 RBS maybe faulty and needs replacing. Ask about RMA options.

Thanks for you helps!

This problem should be firmware problem? or hardware problem? and how to confirm what is the cause of this issue.?
