There's no point in having gigabit fibre to the premises, if your devices are connected via WiFi and you use the ISP's crappy router which struggles to give you 100mb/s six foot from the router.
Round here Toob are putting in FTTP and someone who hadn't had BT's FTTC disconnected yet did a test around the house. Obviously the speed when connected via Ethernet was far higher on Toob, but their WiFi was slower even in the same room as the router, and dropped off to next to nothing further away in the house. Where as slow old BT less-than-full-fibre was far quicker everywhere, due to spending a few pennies more on the in home hardware.
Of course it's easily fixed by replacing the ISP's junk with a decent WiFi router (and a mesh network if necessary), but how many people know they need to do that?
