Comment 164 for bug 1065400

@painterengr, it's a firmware issue instead of a driver one. The driver tried to load /lib/firmware/brcm/BCM20702A1-0a5c-21e6.hcd and it failed to find the file. The .hcd/.hex file can't be included in a distribution due to license issue (it cannot be re-distributed). One way to make it work is to copy the firmware from windows driver. The other is to boot to windows, let windows driver load the firmware, and then reboot to linux.
