That should be close enough to my system, thus I cannot duplicate your problem. I have no idea what the difficulty might be. There should not be a major difference between my BCM4306 and your BCM4318 at this level. I do not see any way to get the firmware onto the live system during booting. If you copy any existing firmware files in /lib/firmware/b43/ on your working system, either from a USB stick, or from mounting a hard drive partition, could you then load b43? If not, perhaps we can get some better diagnostics from a running kernel. Larry
