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?
To be fair they will be trained to follow a standard setup and may not know any better - easier just to say "This is the thing that I know works" after all.
When I saw the ONT had an ethernet port I suspected it might be as simple as plugging in despite what he said!
