Hi, I am poised to buy a 12" powerbook (my first mac ) but I need some help with networking so I know what products to order at the same time so I can get everything set up as soon as possible. I have an ADSL connection currently attached to my Wintel PC via a USB modem (the ugly green manta ray one). I want to wirelessly share the ADSL connection between this PC and my new powerbook. What do I need in order to do this and what are the principles behind it? I would like to be able to use the connection on my powerbook even when the PC is off (and vice versa) Any help would be much appreciated!
