I set up my neighbors Linksys router for his Windows machine using my dual USB iBook, because he couldn't get it to work with his computer. You need an ethernet cable and a web browser (I used Safari) but IE would work. The hardest thing to do was update the software of my neighbors Linksys (it wasn't a necessity but I thought I'd bring him up-to-date; it required downloading some shareware ( which I happily paid $12 for ) and then only took about a minute to do. I am now running a Linksys router as a second node after my Airport on my wireless network.
