(Este manual se probo en Mandriva/ROSA y funciona). Basicamente cuando instalas el SO no es reconocida la wifi. Apesar de que el driver esta instalado en "/usr/src", si intentas ejecutar en consola el siguiente comando
#ifconfig wlan0 up
aparecera un error en "/var/log/messages"

Para esto debemos descargar el siguiente firmware http://emelramone.host22.com/drivers/broadcom-wl-4.150.10.5%20(1).tar.bz2 , y copiamos a la carpeta "/usr/src/". e instalamos:
#cd /usr/src/
# bunzip2 broadcom-wl-4.150.10.5.tar.bz2
#tar -xvf broadcom-wl-4.150.10.5.tar
#cd broadcom-wl-4.150.10.5/

Si la salida de b43-fwcutter es la indicada anteriormente, probamos el manager de redes. Y listo deberiamos ya poder ver las redes y conectarnos.
