@Shih-Yuan Lee Your BCM4321 (14e4:4328) also used bcmwl-kernel-source in kernels before 3.11, but now works better with linux-firmware-nonfree. I found this in http://askubuntu.com/questions/55868/how-to-install-broadcom-wireless-drivers-bcm43xx/60395#60395. That post is kinda a one stop place for everything on Broadcom driver installation in Linux. I wish the Broadcom guys did a more complete listing of cards and drivers for Linux.
