Cant get external ip address when setting up eero 6

[HelenB4]

My fibre 150 went live last Tuesday, but the eero 6 router wouldn't connect to the internet. The app said it had found the eero 6, but it wouldn't get an external ip address. After many hours on the chat to talktalk, they decided the router didn't work and they sent me a new one. Which has the same problem. I feel like I must be doing

something wrong. Please help if you can, I can't afford another week without WiFi

I'm sorry to hear that you've experiencing problems with your service. Which lights are on, on the ONT?
