We have fiber to the premises in our little 12 unit condo building. They installed a switch and all that, that’s theirs, the CAT runs in the walls are the association’s, and anything inside our walls is on us, including the router, but it still works and I’m too lazy to shell out on another quite yet. It’s really quite a layout since everyone has a little bit of responsibility at different points in the building.
Edit: The thought of running CAT6 through a surge protector never crossed my mind but apparently it’s a thing, copper and all
I have fiber to the property but the router is still the property of the ISP not me. Of course they’re not very interested in it and if it breaks they never want it back but they do replace it when I call.
It’s a piece of crap though, so I actually have disabled most of the functions and put it in bridge mode, and then have my own setup, but the ISP don’t need to know that.
