According to Martin Pitt in bug #1298641 Ubuntu should be using the bcmwl driver rather than b43. The trusty installer at the moment is loading the b43 kernel module but failing to load the firmware (because the firmware is not on the cdimage). To use bcmwl needs to be installed and b43 blacklisted.
