How do I install wireless drivers on lubuntu?

I have an HP2133 I bought second hand off a coworker. It came with a certain version of linux (SUSE I believe) but he installed windows 7 starter on it and it was running slower than molasses. I tried fuduntu but it was still running sluggish and the screen kept bugging out and not displaying properly, so now I’m trying lubuntu, but it says I need a wireless connection for best install. I found the drivers for the machine, but I have them in an .exe, and the machine is asking for a .inf, it has an “install windows drivers” tool. How shall I proceed?
