I have just transferred over to Bigpond from my previous provider and notice I am only getting about half my download speeds. I used to get around 650-750KB/s now I am lucky if I get 400KB/s. I am still operating off the same exchange. Had a tech here today and he had issues with dirty lines in our street, said that was fixed, checked my Modem and found it to be a tad suspect, and replaced that. Speed went up to 550KB/s while he was here, now it is back down to a ridiculous 350KB/s. Depending on what download test mirror I use I get as low as 125KB/s.
My distance from the exchange is around 3km. The tech said they were getting nearly max speed at the exchange, so no issues there. It is now nearly midnight here, so cant be too many people on line using bandwidth.
