How do I go wireless with my laptop computer?

Ok, right now I have a laptop computer connected to the Internet via DSL. As of right now I don’t have any infrared anything on my computer. What are all the steps involved in going wireless….What do I need to do to my computer (an old Compaq Presario 1200) and with my ISP?

you need a wireless router and a wireless notebook card to get started.

if you would like to shop online for those, tigerdirect is pretty good on prices.
