I have found out that my eMac/Airport card is faulty. When I installed the card at first, I turned it on but the only thing that happened was the chimes played, and nothing more. After 3 tries, it actually booted into Tiger, but in System Profiler, nothing showed up for Airport. I am assuming there is a problem with the Airport card, so I would like to know what products are good for OS X by way of wireless USB sticks, etc. Any suggestions on how to fix the problem are welcome too.
