Hi All I bought an iMac G5 in 2005 (Ambient Light Sensor) model, I later sold this to a friend. I was speaking to them earlier and they have bought an Airport Extreme and wish to connect the G5 to this wirelessly. I vaguely remember in 05/06 that I wanted to connect it to the net wirelessly but I would have needed to buy a card to put into the iMac G5. I have now looking on the Apple Store and cannot find this wireless card. My question is, was there a wireless card and have Apple stopped selling this? Or do I have real issues with my memory. Any help would be appreciated.
