well what do you need to make faster? do you mean you use a program such as a bit client and want to speed it up? or do you mean you download from the internet directly?
if you're using a bit client, have you tried to open your ports? forward your ports?
if you download from the internet directly, the question is do you have dial up, dsl, or cable? is your firewall blocking you from downloading? what do you mean by slow? what do you expect by fast? like for a karaoke video let's say, how many minutes do u expect to finish downloading this file?
and lastly, it also depends where you are downloading from, some can be a website but the download rate can be slower than a snail crawling race or the turtle marathon competition lol. need more info.
