I boot backbox from a usb flash drive as a live iso. I am trying to install wireless drivers for the dell inspiron b120 laptop using the broadcom b43 wireless radio without rebooting. I tried to follow these directions on this site:
I installed b43-fwcutter and downloaded the two files listed to another usb drive (apsta and broadcom) and copied the files to the running backbox home directory and ran the 6 commands in a terminal.
tar xfvj broadcom-wl-18.104.22.168.tar.bz2
sudo b43-fwcutter -w /lib/firmware wl_apsta-22.214.171.124.o
sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-126.96.36.199/driver/wl_apsta_mimo.o
sudo chmod 775 /lib/firmware/b43
sudo chmod 775 /lib/firmware/b43legacy
This link goes into further detail on installing the driver for the particular chip set. It seems straight forward, however, I am not sure which ubuntu I am using with backbox 3.0.
