    FURRYe38 I’m gonna close this and mark it solved and come back if I have any more issues. I probably won’t get a chance to fiddle around with the routers for another few days.

    Thanks a lot for your advice, which really helped me sort this out

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? If it's got a built in router, This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
https://kb.netgear.com/30187/How-to-fix-issues-with-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. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

    Hi FURRYe38 thanks so much for taking the time to respond. I’m in the UK and the ISP is a company called PlusNet, and it’s their Hub One router I’m using.

    I’ve had a look on their support community site and it doesn’t look like they support bridge mode for that device. I’ve also seen something on here saying you can’t use the netgear app if the RBR750 (or any of their routers) is in AP mode.

    I think AP mode is the most straightforward option (I think) so the question is, will I have limited functionality if I can’t use the app, and if so what will I be losing?

      The Orbi app is limited in any mode. Mostly to see what is connected, you can stop access per device, speed test and thats about it. The app works in both router and AP mode. At least on the 8 series Orbi. I presume 7 series it should as well since there both close in nature and HW san some wireless speed supported rates on 2.4Ghz and memory and LAN ports, FW is same code base. So the app should work on the 7 series as well.

        FURRYe38 Ok great, thanks. I'll have a look at setting up the AP this evening and let you know how it goes.

         

        I also found this: https://kb.netgear.com/26765/Disabled-Features-on-the-Router-when-set-to-AP-Mode

         

        Some of those disabled functions are I think available through the PlusNet Hub One. Also, I've got a fixed IP address from my ISP because I have a NAS that I want to set up a link to a remote backup NAS. So it probably makes sense to keep the functionality of the PlusNet router and limit the functions on the Orbi.
