If I were a router, what would I be?

So, I'm looking at possibly trying to connect a router to my computer, so that i can use the internet on my computer, as opposed to dad's. now this is what i have to work with:

if it asks for a postal code, put in B4N 4H5, it's just a local postal code. I am looking at something $40-60 tops, but the problem is I don't know much about routers, so I don't know what to get. I use an ADSL modem, so, if anybody can help, that'd be great!

AOL should work, and should be fine for the internet connection, just open things in IE instead of running the AOL software.

well, it's for two different computers

ok, what is AOL software? How do I use it for two computers in two different rooms?

At the same time? Okay, I think it would be better not to ask me, I'm not as good with computers as others here (who may or may not have built their own!!!!)

ok. please, i need somebody to help, as i don't know what to get. i do need a router don't I?

i think you do, but sorry im not good with that stuff.
