Remember the Firefox hack that worked????
I've got another one for you....not browser based, this one is for any internet connection, but is particularly good for Broadband.
Download and run (you don't have to install) TCP Optimizer.
If you know what you're doing, you can tweak away to your heart's content...if you don't know, just tell it what speed your tube is supposed to be then hit the 'use optimised' button.......it'll backup your settings so you can revert to them if you don't like the results, then it'll tweak things for you and ask you to re-boot.
Do that, then sit back in wonder as your connection flies
It works

PS Normal caveats.....it worked well for me on my machines and I've used previous versions for dial up accounts for years, but don't go
if it doesn't work for you....use at your own risk

If I spoke to a computer expert
It would have cost me
