Here I am having just had FTTH installed, but capped to a mere 160 Mbps. The main problem I am having is not the router (which handles such a "slow" speed fine) but the wiring throughout the house. It's all copper ethernet and because of the lengths and the fact that the runs must go parallel to some mains electricity cables, it tops out at 100 Mbps. I hope the poster has already put fibre around his house.
