How can I hook up a wireless broadband internet in my home?

An internet connection from an ISP. And a router. A very popular router is the Linksys WRT54G. It takes all of 5 minutes to set-up and in a few months if your router breaks (not that they do, their usually reliable but hey), so when it goes down and you are back to a wire for a few hours you will feel so crippled you wont believe it.
