Been reading heaps of Geekzone threads about people connecting their mesh network routers directly to their Fibre ONT box to avoid sitting behind their ISP's provided gateway (modem+router). Brcsuse, from what I gather, if you don't setup your mesh router as an an Access Point when behind the gateway, then you'd need to fiddle with the ISP gateway to turn off its router + wifi functions else it'd be a double router setup like ONT -> Gateway Router -> Mesh Router (in Router Mode) -> Mesh Satellite?

So, I'd like to do the same but for the life of me cannot seem to get it to work. Here's what I have and what I've tried:

- Orbi RBK23
- Chorus fibre ONT
- new Skinny fibre broadband (7th day waiting for new Skinny gateway to be delivered due to NZPost delays)
- old TrustPower gateway -> THIS ACTUALLY WORKS ON SKINNY after manual modem configs

But, I don't want to have to use any ISP gateway between ONT (since that should have a built-in modem) and the Orbi router as others have allegedly accomplished.

Tried using this PBTech guide: https://www.pbtech.co.nz/NetgearISPSettings#sparkorbi

However, this PBTech article doesn't specify the Orbi VLAN tagging needs for Skinny but what I still don't understand is why neither Internet Settings + VLAN/Bridge tagging options work for Skinny? When I tried both, the Orbi eventually just ends up with the magenta/purple ring to say No Internet.

I feel like I tried this when I had TrustPower too and that also just got the purple ring.

What am I doing wrong? I'd really like to not have to be reliant on an ISP Gateway to use my mesh wifi regardless of which ISP it is. Because else, is having the Orbi in Router mode and the ISP Gateway configured like it is out of the box, wouldn't that cause like double-routing issues?
