b43 and b43legacy are drivers for the 802.11b/g/n family of wireless chips that Broadcom produces.

• b43legacy: supports BCM4306 Rev 2 and cards that have only 802.11b capability
• b43: supports all other models

The b43 drivers require proprietary firmware to be loaded onto the wireless chip before it can operate.
BCM43228 is present in supported list :)

PCI-ID	Supported?	Chip ID	Modes	PHY version	Alternative
14e4:4359	yes (3.17+)	BCM43228	a/b/g/n	N (r16)	wl

The Broadcom wireless chip needs proprietary software (called "firmware") that runs on the wireless chip itself to work properly. This firmware is copyrighted by Broadcom and must be extracted from Broadcom's proprietary drivers. To get such firmware on your system, you must download the driver from a legal distribution point, extract it, and install it.

b43-fwcutter tool will help extract firmware from the Broadcom driver.
