Well that rules out a badly set up PC.
I'm guessing you've done the usual checks of plugging the modem directly
into the master socket behind the BT faceplate - and testing with two
different filters, with no other phones/filters plugged in anywhere in the
home, etc. etc..! No Number 3 wires connected anywhere (just 2 and 5).
Deactivating the modem's wireless capabilities during a test as well... just
in case a near neighbour is hogging you traffic..!
Try running a test on
http://www.speedtest.net/ and see how smooth the Green
Graph is during the download test.
Also.... you haven't got a huge Upload Speed by any chance have you?
