I have been looking all over to get certain broadcom wireless network cards working in Mandriva, then I found this link.

However it is important to upgrade
b43-fwcutter to the latest version especially for Mandriva 2011
Installing the firmware on Mandriva Linux 2011 or higher
Open a terminal (in your application menu in Tools you will find Terminal or Konsole)
Execute the following commands, by copying and pasting them in the terminal:
wget
http://mirror2.openwrt.org/sources/b...mipsel.tar.bz2
tar xjf broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
su
b43-fwcutter -w /lib/firmware/ broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o
modprobe b43
