From > https://forum.openwrt.org/viewtopic.php?id=24208 : >> b43 in Backfire works on most BCM4306-BCM4318-based cards, included master (AP) mode.

Hi, I just wanted to drop you a mail back to say thanks a lot for your help and for your hard work. I now have wlan on my mbp thanks to your instructions- life saver! :) -------------- next part -------------- A non-text attachment was scrubbed...
