I recently had FTTP installed (UK - YouFibre) which came with its own router connected to the newly installed ONT.
Previously I was on Virgin Media, using their router on modem-only mode and connected to my Google Nest Wifi.
Despite the engineer telling me I had to go through the supplied YouFibre router first, on a whim I switched the Google wifi from the Virgin router directly into the Ethernet port on the ONT. I was pleasantly surprised to find it worked immediately without any additional configuration.
This is great - one less device plugged in etc. but I wonder if there is anything I should be aware of in doing this?
Am I just being paranoid?
The ONT gives out an Ethernet signal. If the Google WiFi gets the IP address you are good. The one thing that the ISP can say is that you are not supported if you have an issue because it’s not connected to their router. If that’s the case swap out routers when you have issues.
I’ve been running Google WiFi straight to my ONT for years.
