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:
http://linuxforums.org.uk/index.php?topic=5842.0

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.

cd ~
tar xfvj broadcom-wl-4.150.10.5.tar.bz2
sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/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.

I am not familiar with Backbox.
However, to install the driver for the Broadcom BCM43XX chipsets on Ubuntu you need to have the
firmware-b43-installer and the b43-fwcutter packages installed.
See this: http://askubuntu.com/questions/55868...s-card-bcm43xx
To get the Broadcom BCM4311 wireless working on my Lenovo laptop I just installed the firmware-b43-installer and the b43-fwcutter
packages and it worked. I did not even bother uninstalling the bcm-kernel-source package as it says there. I think it is automatically uninstalled when you install the b43 firmware packages.
I don't know what that apsta package is or why you would need it. Just install the firmware-b43-installer and the b43-fwcutter
packages and you should be good to go.

The b43-fwcutter can be installed using synaptic installer. I downloaded firmware-b43-installer_015-9_all.deb to another usb drive and copied the .deb file to the running backbox ubuntu /home/Downloads, then ran in a root terminal:
dpkg -1 firmware-b43-installer_015-9_all.deb
It complained:
Problems were encountered while processing:
firmware-b43-fwcutter no such file or directory

However, b43-fwcutter was installed via synaptic so I am not sure what it is complaining about. Is the problem from where I ran the .deb file in /Downloads?
