I've never touched Linux before, but I've of course heard tons about how its better than Windows, both by credible sources and by rabid zealots. Well, I found out about Knoppix not long ago, and figured I should try it, seeing as how it's small and portable and won't mess up my computer. I downloaded, burned, and booted Knoppix, and everything went fine. However, I have no idea how to get online with it.

I have a D-Link DWL-520+ wireless PCI adapter installed in this computer and a D-Link router downstairs (can't remember model number, sorry). Is there a simple guide to getting online under these circumstances, or can somebody help me with this?
