Re: Latest firmware for RBR860
I subscribed to a new ISP back in Nov to get an RBR860 upgrade. It came with a non public firmware version way higher than currently listed one. As I had to buy my own satellites and these updated to ...

The ONT is a hyper fibre Nokia 110.
https://www.chorus.co.nz/help/ont/hyperfibre-type-110
I replaced all my ethernet with Cat6e.
I didn't think I could connect to and test the ONT from its 10GE/WAN port without the RBR connected. Worth giving this a try in the future when I need to eliminate my RBR from the mix.
The speed tests were fine from the RBR's webUI Speedtest (or Orbi app) and anything connected via wifi. It just didn't like LAN.
I can't recall the ISP's version but it was a very different number sequence suggesting it was a bespoke version for some local oddity. However, as the ISP also offers BYOR, had I bought a 860 then I would have had to run the public firmware. So I thought there's little risk in downgrading.
I was able to downgrade from the ISP's f/w fine. I did this as I assumed running my own sats on a way different version was asking for issues.
Rather than upgrade tom v15 and then factory reset and provision many hours of config from scratch (static IPs, VPN, device details etc), couldn't I just restore a backup after the factory reset? I've done that before and it's been fine.
IPv6 is disabled on the RBR - I vaguely recall this being one of the things the ISP advised me to change, along with removing the WAN credentials to sign-in (previous ISP had a username and password) and adding a VLAN tag group.
Is it worth running v15 only on the sats?

The link you posted shows that unit as a ONT and full on built in wifi router. If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended and can cause problems. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

Try option #2 first...
First try a factory reset on the 860 after v.15 is loaded on the RBS first, then RBR lastly and after you set the ONT to one of the options above. Hoping that one of the options will eliminate the issue you saw on the Orbi system. Can also try AP mode as well.
FW versions need to be on same version between the RBR and RBS.

I should have elaborated - the ISP has not deployed the built in router or wifi features and uses it as a plain ONT, supplying a Netgear RBR or allowing BYOR & satellites.
There is no SSID enabled on the ONT. I did ask them if this was a supported option and they said no as the ONT is installed separately by the fibre backbone telco (Chorus) for ISPs to come along and connect their router/modem/mesh of choice, or allow BYOR by the customer. Interestingly, they have stopped handing out the RBR and have switched to a TP-Link instead and even discourage BYOR. I wonder if they have had cost, sourcing or reliability issues with Netgear, hence changing to TP-Link. This creates a potential risk should I get a hardware failure - I'd have to buy my own replacement RBR to work with my additional satellites or switch to their TP-Link (and still buy my own satellites).

OK, just making sure with the ONT. If that is the case then thats just the interface unit for the ISP services.

I gave v15 another try but with limited time I just updated without any factory resets. Sats and RBR updated fine and came back online quickly, but within a few mins the ethernet performance from the Mac to the RBR showed the same fault - starts at 900gmps download on the speediest or there about and then quickly drops to near zero.
Reverting back to v7.2.6.31 and ethernet performance was solid 940/900 or there about.
If I get an opportunity I will try a factor reset update but I'm not convinced this is a vital step and nay only be worthwhile when devices crash when updating.
