Virgin Media Hub 3.0 VMDG505/TG2492LG-VM and Orbi RBK50 - HELP!

[CmdrBond]

I am trying to set up a new Orbi RBR50 onto my Hub 3.0 and I cannot get it to detect the internet.

1. I believe my Hub is successfully in modem mode as the light is solid magenta/red/whatever

2. Directly connecting port #4 (lowest) to my laptop gives my laptop internet.

2a. Doing an IPCONFIG /ALL shows the Ethernet adapter as follows:

Connection-specific DNS Suffix : cable.virginmedia.net

DHCP Enabled : Yes

IPv4 Address : 82.xxx.xxx.201 (redacted)

Default Gateway : 82.xxx.xxx.1 (redacted)

DHCP Server : 62.xxx.xxx.xxc (redacted)

DNS Servers : 194.168.4.100 and 194.168.8.100

So all seems well.

But take the lead out of the laptop and plug it into the WAN port on the Orbi, and the Orbi refuses to see the internet connection. (Laptop directly connected to Ethernet port on orbi)

Connecting via DHCP

Forgot to mention I previously had an RBR40 connected to an original super hub, but something fried the pair of them. The RBR40 won't even turn light up, it just clicks a bit. So I can't test it with that (which was working fine until it died).

"I believe" isn't exactly reassuring.

Are you convinced that you are in modem mode.

I'm not sure that I follow the narrative here. Take this bit:

Do you mean that simply by plugging the laptop into the Orbi kills the Internet for everything?

I am having a  bit of trouble working out what is plugged in where in this scenario.

This would be a double NAT (two router) condition which isn't recommended. 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. 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
