Geek Stuff: understanding Tech Details of WiFi for WiFi LAN & etc

I don't put to many tech things on this blog.

But this Ars article on WiFi looks very good.

Hard core computer Geeks will probably think it is fluff, but for others, like me, that usually only learn enough to use computers well I think this is a very good article.

I am in the planning stages for setting up good gaming quality home WiFi LAN, so I am mining this article for hints and tricks for setting one up.
