Linux support for the Broadcom 4331 wireless chip used to be poor. This chip has vendor- and device id 14e4:4331 and identifies as

$ lspci | grep 4331
03:00.0 Network controller: Broadcom Corporation Device 4331 (rev 02)

As of this writing, there is no driver in the kernel, and with ndiswrapper there are many random system lock-ups. As a result, Macbook Pro 8,1 (8,2 ...?) users running Linux couldn't use the internal wireless chip. Recently, the situation has improved thanks to three patches submitted by Rafał Miłecki and Larry Finger. The driver is announced for kernel version 3.2, but if you don't want to wait for this kernel it is possible to compile and use the relevant module with older kernels.
