Re: Is there any benefit to have a wired backhaul for an Orbi Mesh system?
In my experience no! I’ve had an RBR750 and 5x RBS750s for a couple of years. Although for some of that time I’ve had pretty good Wi-Fi network, I’ve spent countless hours/days/weeks fiddling tryin...
Would need more details and feedback on questions given to better help you figure out the "I’m not sure why".
Sorry, last reply was in fact a reply to the post before yours. Thanks for taking the time to help.
In answer to your questions:
Firmware V4.6.14.3_2.3.12, all satellites up to date.
Property size is roughly 5000sq feet. Lots of thick cob (mud) and stone walls. Minimum distance between APs is 20 feet (when walls are v think), max 40 feet (across garden to garage). I have read the recommendations about optimal placement/distance and have spent a lot of time experimenting with different positions, as well as reducing the transmit power of both bands.
Switch was a TP link SG1005P unmanaged gigabit switch. It's not in there at the moment, but I tried with and without as a test just in case.
I have tried different cables, but the current ones (which I disconnected last week and it's been fine since) were brand new, Cat7 shielded. The RBR750 confirms that when connected they manage to negotiate a full speed connection, looking at the statistics page (1000M/Full).
I have 5 satellites. Now that they are all on wireless 5GHz backhaul, it's all working pretty smoothly, with generally good handoff and roaming, reasonable speeds and quick device joining. Testing speeds from APs to the router with the openspeedtest add-on for Home Assistant (ethernet to router) I get generally get 300-600mps wirelessly with latency of a few ms.
It is probably worth noting that I do have a potential double NAT situation going on at the moment, as I have a Starlink v2 router providing my internet. This is plugged into the WAN port of the RBR750. Starlink does not appear to be fully compatible with Orbi (numerous examples in these forums of people with similar experience), and I have found that when enabling bypass mode (as recommended by Starlink when using a 3rd party router) on the Starlink my network (in terms of latency and speed) is actually much worse! So whilst I do have a potential double NAT situation, my network is currently performing the best it has for a long time with the Starlink in router mode and the Orbi using 5GHz backhaul. The problems with wired backhaul being less stable than wireless pre-dated the Starlink router (I had an ADSL modem before that) so I had assumed the two were not linked but I thought it was worth mentioning just in case.
Your system is behind on FW as well:
What is the size of the home in Sq Ft?
Where do you have the RBR and RBS placed with in the home and remote locations?
Can you draw us up a floor diagram and lay out with indication of where the RBR and RBS are placed with distances please?
Please describe the issues and problems seen when the RBS were all ethernet connected...
Some non NG branded switches can also impact how the RBR and RBS work when ethernet connected. NG GS-105/108v4 and GS308v3 series switches work for Orbi systems.
For the 7 series Orbi system, CAT6 UTP cabling would be recommended and sufficient for ethernet connections between the RBR and RBS.
Recommended connection paths for ethernet connected RBS:
Depending on size of home and placement of RBS, 5 RBS maybe too much. I have a 5k sq ft home and can get away with one RBS ethernet or wireless connected when I have my 750 series online.
Hi,
Thanks for your reply.
In answer to your questions:
I'm surprised about the firmware - I've just rechecked on the router browser config page and it states that all the devices are up to date - is this not accurate?
My home is approx 5000sq feet. Two floors, but the problem is that much of it is made out of cob (mud) or stone and the walls and some of the floors/ceilings are very thick. I have placed the router centrally upstairs, and done extensive experimentation with the position of the satellites which are all downstairs. I'm aware that optimal placement is 30 feet or so, but in certain areas I've found that things worked much better with a smaller distance for the wireless backhaul due to the sheer thickness of mud and stone (RBSs 2 and 3)! That's why I've got 5 of them.
The thick walls also make routing ethernet tricky, but I managed to route two ethernet cables from the RBR to the RBSs numbers 1 and 3. The other RBSs run of wireless backhaul. They are all arranged in hub/spoke orientation, apart from 5, which is daisy chained from 4. 5 is in a garage with a clear line of sight and works pretty reliably.
So I was running a mixed ethernet/wireless backhaul, but have since ditched the wired part and it's all 5GHz now. The whole network was generally less stable when these two ethernet backhauls were connected. Devices took longer to connect, sometimes several minutes, and would drop connections. Pings and speeds were less.
I only used a switch briefly as a test
I'm aware that a minimum of Cat 6 cable is recommended, I went with Cat 7 to future proof things. The cables are all brand new and shielded/braided.
I followed the link you mentioned about connections.
I've attached a floor plan. Sorry it's quite busy! Hopefully it's all self explanatory.
I very much appreciate you taking the time to help!
Thanks

Some times NG doesn't auto update or push FW to users systems. NG finally gave control of this back to users after many years of users complaining of FW being pushed that broke there systems. So if you don't see it in the FW update page or Orbi app, please check NGs download page or here in the forums. User can Manually update there systems if they choose too.

I presume the marking of RBS750 Upstairs near the door and stone wall is the RBR?
Looking at the floor plan, though with the building materials in the mix, RBS 2 and 3 maybe problematic, even being close at 20 feet, there could be some too much wifi over lap here. Any chance of getting RBS2 ethernet connected so you could move them farther away from the RBR and each other?
Just curious on RBS 1 and 2, If you turned these OFF temporarily, would you see problems here?

This maybe indicitive of the RBS not having good ethernet connections to the RBR via ethernet which cables and such would need to be checked, or, Wifi signals and such in the home between all the RBS is too much when ethernet connected. Something to test would be to reduce the RBS that are wireless, then leaving the ethernet connected RBS, test and observe.
Something else to try as well if you can get all RBS ethernet connected. Turn down the power on the RBR from 100% to 25% and test. Being that the RBS would be ethernet connected thus don't need full wifi power, the coverage from each RBS could be reduced to a lower setting, and maybe getting RBS2 moved farther away or maybe reduce the RBS count by one while ethernet connected. I do see the need to keep RBS3 ethernet conneted. Something I do with any Orbi I have, if two RBS are ethernet connected, power goes to 25%. Still get great coverage and operation.

This switch has some PoE features as well which is not recommended for Orbi systems. I would recommend something NG next time you want to put a switch in between the RBR and RBS. NG GS-105/108v4 and GS308v3

Over all, there maybe several factors there that could be problematic over time. House building materials, Placement and distances with regards to wifi over lap, wireless or wired. Cabling between the RBR and RBS. Too many RBS deployed, however given building materials at play.
If you think the system run Ok as you currently have it, then I guess keep it that way. Just know this maybe hard to troubleshoot in the future should something happen. For any MESH System. Building materials are definately hard to work with. Nature of that beast.
