Just wanna say thanks to all of you who helped my in time of crisis. My ibook G4 is now up and running, with a 60 GB HDD, Leopard and out of the blue, it is not freezing anymore while using the Airport Extreme Card. Apparently when I opened up the ibook G4 to install the hard drive, the problem disappeared but I didn't know till today when I decided to give it one last try before getting a usb wifi adapter. Thanks for the help! PowerPC till it last or any Chinese company decides to manufacture laptops with PowerPC processors!
