I am having issues with getting wireless to work on my iBook G4. I have followed the FAQ and installed the b43-fwcutter tool then I downloaded and extracted the firmware. Normally in Debian and Ubuntu I would run the command sudo modprobe b43 to wireless working. However I cannot get it work. I have verified the kernel modules are configured correctly. I am not sure what else I am missing.
