I have an iMac flat screen G4 800 MHz running OS X 10.3.5. I am buying a notebook and want to set up a wireless network with an Airport Express. My first question is do I need to buy an Air Port Card and install it in my Mac. If so, do I need to buy the old Air Port Card or can I use and Air Port Extreme Card? It appears to me to be the latter. What is the difference between using the old Airport vs. the newer Extreme??
Once I install the card and hook up the Airport Express, is it easy to configure?
Thanks for your help!
