Alright, I'm not actually that stupid. :)
I'm talking about wifi for arduino... like this (http://www.sparkfun.com/products/9954). The page mentions that it "equips your Arduino the ability to connect to 802.11b/g wireless networks." But is this internet? Could I use this in place of an eth shield? (I am thinking not) Which leaves that it just connects to the network... but what can it do? How do I interface it with a computer? Or is it just wireless internet?
