what has FTTC and FTTP got to do with USING your OWN Router.....
and I know A LOT more about FTTC and FTTP than you I work for BT openreach installing FTTP, and USED to install FTTC...
I say again thinking it alters ANYTHING shows how much YOU know about both....
do you THINK there is no such thing as a router with built in ont ?????
You may install it, but it don't mean you know about it, like a sky bloke sticking a dish up and connecting it to a some boxes,, just because he can do that, don't mean he knows how it works.
A lot of things are just following the instructions these days.
I am, not saying you don't know more about it, just saying that installing something don't mean you know more than somone else.
