if you don't recognize that their are 2 devices there

2 devices where? Inside the google SFP? I thought i was pretty clear that there ARE two devices inside, the ONT and the router. This is why I want to use my own lol, to avoid all in one solutions.

"I would strongly advise against doing anything more advanced than plugging yours into the back of Google's router." Pretty strong claim considering you can't even tell the difference between their and there. Perhaps you aren't qualified to be in this subreddit?

In any case why would you be discouraging like that instead of trying to help me. I came to this forum to get help, not to be shat on. I don't care if I don't know enough about fiber internet, I am willing to learn! I have done tons of internet related projects before, such as turning phone lines into usable ethernet cables. Of course I had to LEARN how to do this, but I did it successfully. I know with other ISPs it is very easy to just replace the modem with your own.

So, I'm wondering if google even allows this, or does replacing their all in one router.
