tonyhughes: Re-do your wiring... replace your modem line cord... don't use an extension phone cable...
I know you are on naked DSL, buuuuut, do you have a line filter on there?
tonyhughes: Considering your upload speed is what it is, your download speed is probably "acceptable" (from a technical viewpoint).
Borrow someones modem, and see if your stats change significantly.
corksta: Just tried that now, 202KB/s was the maximum I could get, sat at about 180 though. Someone tell me it's Orcon and not the wiring in our house!
