Broadcom Wi-Fi adapter on Linux

Some laptops have integrated Wi-Fi adapter which Linux doesn't recognize by default. Probably because the drivers are proprietary. Ubuntu suggests automatic installation of the driver but does it optionally. Lots of other distributives don't do this at all.

I'll describe the process of driver installation for my Wi-Fi adapter in PCLinux. As I could understand on forums, this type of adapter is widely spread and installation process is almost the same for all distributives.

First of all, let's check that system has found our adapter:
$ lspci | grep Wireless
05:02.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
Now lets install fwcutter:
$ sudo apt-get install bcm43xx-fwcutter
Then download driver from here, extract the archive and install the firmware:
$ tar -xjf broadcom-wl-4.150.10.5.tar.bz2
$ cd broadcom-wl-4.150.10.5/driver
$ sudo b43-fwcutter -w /lib/firmware wl_apsta_mimo.o
After all these steps Wi-Fi should start working. At worst, you can try to reboot your laptop.
