hey there guys.
this tip was stated before, and it was brilliant and i dont want it to die out.
go here and download a little programme called TCP Optimizer.
you do not need to install a thing, it opens on its own.
once your in it, choose your connection type and then, you will see that it makes settings for you.
these settings are the best for your connection type.
click on apply (cant remember, its either apply or OK cos i used it long ago) and then restart your computer.
when you reeboot, you will notice a difference in your webpage loading speed and downloading speed (well, at least you should, many have).
i really hope this works and helps you,
