I just inherited an iMac G5 (10.4.11) which I would like to add to my existing PC setup. I currently have a DSL modem (2Wire from Qwest, my local phone service) hardwired to my PC. I understand if I want to connect the iMac wirelessly I will need an Airport connect. But I'm confused about the types available. There is a basic Airport Card, an Airport Extreme Card, and an Airport base station. Which of these would best suit my needs. BTW, distance from the modem is not a factor. The modem is about four feet from the iMac. Advice much appreciated.
