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...

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?
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.
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.
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?
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.
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.
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 only used a switch briefly as a test
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
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.
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.
JamesSimpson I'll second some of FURRYe38 's comments re: number of satellites. I have a 4500 sq ft house, lots of heavy walls - a basement and 3 floors above it - original house built in 1862, completely gutted and redone in 2010.
I original put the RBR in the basement, where the cable line came in, I put an RBS on each floor. I had nothing but troubles, wired or WiFi backhaul. So, I took a signal checking app on the Mac (two - WiFiExplorer Lite, iAnalyzeWiFi), disconnected the satellites, and started walking around and seeing where signals were strong and weak. I found I could EASILY have strong WiFi throughout the home with just the RBR in the basement, 1 RBS on the 1st floor, 1 on the 3rd floor.
I have seen so many people over-saturate their houses with satellites - it just causes lots of problems.
Here is my procedure for how to figure out optimal location based on signal strength - note, the RBS location needs to be DIFFERENT if you are using wired vs. wireless backhaul! Maybe this will help, I have posted it here before...

I would highly recommend to do this right, you need a software app that shows real time WiFi signal strength. There are a number of free ones. I use a Mac laptop, and walk around the house running either/both of 2 tools - WiFi Explorer Lite and iAnalyzeWiFi. Both are free and in the Mac App store. I am sure there are comparable tools in the Windows world, if not more of them. Both tools will give a real time view of ALL signals in your house where you are standing. As a bonus, you'll even see neighbor's signals if they are close enough, so it gets really easy to determine channels to set up with the NG routers for 2.4GHz and 5Ghz so that contention between networks is minimized.
Now there's two options with how you do this - you didn't say if your backhaul would be wired or wireless. With wired, pick the WORST signal area that you can get a wire to, to increase the coverage. With WiFi backhaul, pick a STRONG signal area so the backhaul connection is fast and reliable.
I would recommend getting an RBR and 2 RBSs to start. Get the RBR working, walk around with your laptop signal app, and place the second RBS - THAT'S IT. get them both up, and then do some more walking around to see what the final strength is. You can see them in RSSI so it doesn't take any "figuring" to know if the signal is good enough for WiFi. One e that is working, you will know whether you have an area with weak signal to set up the second RBS. Try putting it as far as you can in the apartment from either the RBR or RBS - I think Netgear recommends 30 feet minimum? Others can chime in.
With 2 RBSs in place, just keep walking around checking signal strength - and do some speed tests. Only then will you know if you have an objectively weak signal area demanding a 3rd RBS. Keep in mind as well, if that area for the third (or even the second) RBS is weak but small in size, you may need to reduce the signal power from that RBS so it doesn't overlap - you want it just strong enough to cover the weak area. Note on the two signal apps I mentioned above, I can see signals from each RBR and RBS individually - so I know if I have a strong overlap in a region of the house.
I really think you will be shocked at how few satellites you need - certainly well less than 6 unless your walls are like Fort Knox. I was SHOCKED how strong the signal is, in some cases going to a room directly above on the next floor, but at the other end of the room - it has a lot of interference to get through but it does GREAT.
Good luck and let us know how it goes - but please don't buy 6 RBSs until you know objectively you need them - the overlap in signal between them will destroy the successful operation of your mesh!
Thanks all for your comments and help with this. All food for thought.
I should have mentioned that I have been using the WiFi explorer app on my Mac, and did as suggested when working out the optimal placement of my satellites in the first place.
I wan't aware that the firmware update page on the browser based config page was misleading, so will definitely try that.
I will also continue to experiment!
Thanks again all for your help!
Hope you can get it all working to your liking and in good operation.
Good Luck.
