Can I split an Internet Connection?

[eBolasNiper]

Hey

I do not mean by using a Router

What I mean is...

I have FIOS hooked up to a router right now using 2 PCs

My speed is 20MB/s DL and 5MBs UL

I do a TON of Downloading, which slows down my entire Network so both PCs run slow

is there some way to maybe split up my package

for example, take the 20/5 package I have, and split it up

so that I can use one half for all my downloading, and the other half for my usual browsing ect,...

That way, no matter how much DLing I do, it wont slow me down, because the 2 connections are split / seperate

any info on this, would be delicious!
