Greetings all, I am a PC user turned Mac-Man. I recently purchased my first Mac. Being that I know nothing about Macs all I know is that it is a used 400 MHz Power PC G4 running OS 9.2.2. I was using a PC/Laptop to connect wirelessly to my network at home and was told that I could also connect my Mac this way. Ihave been told to purchase different types of cards for my machine. The tech support with my internet provider said to get an Airport Express/Extreme card, while the folks at the Apple store said to get an older Airport Card which they no longer carry. I am not at all computer savvy and purchase dthe Mac to get in touch with my creative side. Would anyone know which card is the appropriate card and where I can get one? Thanks for any help or suggestions and I look forward to becoming part of the Macosx community.
