Here in Hereford we had slow internet down copper wire, but a few months ago Openreach installed FTTP - fiber to premises, which is better and faster than the FTTC they were installing in towns last year. Because I think with FTTC there's a copper wire from cabinets to your premises
First they strung a new optical cable along telegraph poles to a loop at my wall. Then screwed a box to the outside of my wall and connected and tested the cable.
A few weeks later another lot came and put a cable from that box along holes and a route i'd already prepared to a box inside. From this there's an cable to the BT homehub - which has wifi .
