>> IP profile for your line is - 135 kbps
Thats the reason for your very slow speeds - more info
IP profile.
At some point over the past few days you have had a very low sync - probably due to some sort of interference on your phone line.
Even now your sync speed isnt that great considering that you say you previously had a 3Mb connection.
Your sync speed depends on local conditions and there isnt anything that PN can do about that part, unless you have an actual fault on your line.
Checking your
line stats may throw up an indication as to what may be going on... but at this time of year its highly likely that there is something causing
Low SNR problems... xmas tree lights often being the culprit.
