slow connection speed

Hi,
over the last few months, I have notice a decrease in my internet connection speed. I am running Tiscali Broadband 512k. the best connection ever recieved was 500k but now I am lucky if I achieve 350k. my down load rate has dropped from 49kbps to as low as 17kbps can anyone advise why???

Maybe its because more and more people in your area are signing up for broadband, affecting the contention.

What do you get on the ADSLguide speedtest? It's probably because Tiscali are crap, check the forums at the aforementioned site.
