How much of the download speed is a function of the ISP, and how
due to appalling quality of BT Openreach lines over which most
broadband runs? In other words, what is the point of changing from
"slow" ISP to a "faster" one if the rate-limiting step is that you
miles from the exchange over wire that has wet, corroded joints?
Very little, but Openreach can provide the ISP with line length and
quality information which will allow an estimate of speed. Also, a
good ISP will apply pressure to Openreach to repair corroded joints.
The only way one could get a guarantee of a specific speed would be
.... or cable.
