About a month ago I had a problem after installing ubuntu which resulted in my Wireless card not working because I didn't have the required firmware on my installation media (USB), if I hadn't had a way to connect to a physical Internet connection I pretty much wouldn't be able to use my Internet, and find out about firmware-b43-installer which I had to install while connected to the Internet.

So the main question is this: Is there a custom way of including this firmware (firmware-b43-installer) in my USB installation media, so the next time I install Ubuntu the from the USB I would have the firmware installed or be able to install it without a physical Internet connection.

I prefer to do this a VM personally. I configure it how I like and install my broadcom sta driver and then remaster it so I have it all there during a liveusb boot.

Apparently the answer is on the Ubuntu Community Wiki: WifiDocs Driver bcm43xx, b43 - No Internet Access. If you need the driver installed in the live session, you can make a USB drive bootable with a live session in persistent mode (meaning it saves your changes to the session), that should keep driver configurations.

If you do not have any other means of Internet access on your computer, you will have to install b43-fwcutter and patch packages from the install media. After that you will need to setup firmware manually (without the firmware automatically downloading and being set up).

Step 1.

b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online.

Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

Double click on the package to install or in a terminal (under the desktop menu Applications > Accessories > Terminal) navigate to the folder containing the package and issue the following command:

:/b43-fwcutter/$ sudo dpkg -i b43-fwcutter*

In case you couldn't find the folder, wubi keeps it as a hidden folder so you have to mount it. Follow these steps:

~$ sudo mount -o loop /host/ubuntu/install/.fuse_hidden0000000400000001 /mnt

~$ cd /mnt/pool/main/b/b43-fwcutter/

~$ sudo apt-get install b43-fwcutter

~$ sudo dpkg -i b43-fwcutter*

As for the patch:

~$ cd /mnt/pool/main/p/patch/

~$ sudo apt-get install b43-fwcutter

Then unmount:

~$ sudo umount /mnt

Step 2.

On a computer with Internet access, download the required firmware files from and

Step 3.

Copy the downloaded files to your home folder and execute the following commands consecutively in a terminal to extract and install the firmware:

~$ tar xfvj broadcom-wl-

~$ sudo b43-fwcutter -w /lib/firmware wl_apsta-

~$ sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-

Step 4.

Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.

Note: A computer restart may be required before using the wifi card.


Note: The install media contents are mounted under /cdrom of the filesystem.

Step 5.

For temporary use with the LiveCD and LiveUSB environments, instead of a computer restart, in a terminal issue the following commands:

~$ sudo modprobe -r b43 ssb

~$ sudo modprobe b43

Note: Allow several seconds for the network manager to scan for available networks before attempting a connection.

I'll try out these things. – Roberts Jan 8 '12 at 21:41
