The drivers are called bcm43xx in mainline kernels, and b43 and b43legacy in wireless-2.6 and 2.6.24 and later. This number is read by the driver ssb, and the correct choice for your device is made at that point. If your card is a BCM4306 Rev 2 or only has 802.11b capability, it uses b43legacy. The choice of which driver your card uses depends on the revision level of the 802.11 core. I found this site,, very helpful in solving this problem.ī43 and b43legacy are drivers for the 802.11 B/G/N family of wireless chips that Broadcom produces.
After installing Linux Mint 12 on my Compaq Presario CQ40-410AU (圆4 bit) laptop, the wireless LAN Broadcom BCM4312 802.11/bg doesn't work out of the box.
