A lot of the problems I get here, in the top left hand corner of Wales, are directly related to lack of fibre optic.
Slowness applies to all internet use.
That said I have spoken to my ISP and they have, by means of some upgrade to local (ie local to me) of cabling, increased my average download speed from 2.3 to 14mbs ..... that and a little patience seems to have solved most of my problems .... although the VP deffo runs slower than "The Other Place" most of the time.
