Ahh well … not a problem if wireless keeps working 
… how’s it going ?
So far so good!
So that exercise results in a kernel panic when I attempt to activate the driver from Additional Drivers screen. I also saw in the article that this would work for the 4318, but the description in the AD screen doesn’t mention that part.
Hello to all!! I’m new here in the forum and I have the problem that when the center appears, the install button is disabled so I can’t click it!! 
What can I do?? Please help me!!
Can people please let us know which version and architecture of Ubuntu you are using … eg. 12.04 32bit … so I can re-test these instructions.
These instructions are quite old now, and I haven’t tested them with recent versions.
–
12.4 32bit!!! You found it!! 
haha
mary … I take it you mean when you click on the b43-fwcutter.deb and patch.deb files, software centre opens but the install button is greyed out ?
If so … here’s another way to install those 2 packages … create a folder on your desktop called b43 … copy both the b43-fwcutter.deb and patch.deb files into it.
Now open a terminal (Ctrl+Alt+T), and run these commands in sequence:
cd ~/Desktop/b43
then
sudo dpkg -i *.deb
That will install those 2 packages … then carry on with the original tutorial.
I have only found the deb file and I didn’t continue to the others because of the grayed install button of the center. Let me see if these things you just said work. And thank you soooo much for the direct answer!!!
I mean the first deb file only, sorry. Let me see.
OK, new instructions for an offline install of b43-fwcutter and firmware for Broadcom Wireless cards in Ubuntu 12.04
(patch.deb is no longer necessary … and there’s new firmware linked below)
With the 12.04 LiveCD inserted …
Create a new directory on your desktop called b43offline
Now navigate onto your Ubuntu 12.04 LiveCD, and go to pool > main > b > b43-fwcutter directory
Copy the b43-fwcutter_xxx-x_xxxx.deb file to the b43offline directory you just created on your desktop.
If you don’t have a LiveCD … you can download the b43-fwcutter_xxx-x_xxxx.deb file for your architecture from one of the mirrors at this link:
http://packages.ubuntu.com/precise/utils/b43-fwcutter
and place it in the b43offline directory you created on your desktop)
Once you have the b43-fwcutter_xxx-x_xxxx.deb file in the b43offline directory on your desktop … open a terminal (Ctrl+Alt+T) and run:
cd ~/Desktop/b43offline
then
sudo dpkg -i b43-fwcutter*
On another PC with internet access … download these 2 (firmware) files:-
http://mirror2.openwrt.org/sources/broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
and
http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
and copy them both to the b43offline directory you created on the Ubuntu desktop.
Open a terminal, and run these commands in sequence:
cd ~/Desktop/b43offline
then
tar -xjvf broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
then
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o
then
sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
then
sudo chmod 755 /lib/firmware/b43
then
sudo chmod 755 /lib/firmware/b43legacy
then
sudo modprobe -r b43
(don’t worry if that command fails … just carry on below
then
sudo modprobe b43
Wireless adapters that use the b43 drivers should now spring to life
If that doesn’t work … try changing to the b43legacy driver with:
sudo modprobe -r b43
then
sudo modprobe b43legacy
Once it’s working … feel free to save/move/delete the b43offline directory from your desktop

Can you please tell me how I can uninstall the second deb file because I already installed it with the way you told (*.deb)… 
:s
What’s the output from:
dpkg -l | grep b43
?
–
I’m in the b43 folder, on desktop and from this path, I wrote the command you said. The output is:
dpkg-query: error: package name in specifier ’ grep’ is illegal: must start with alphanumeric character
Basically, because from the other instructions I installed both deb files and now you said I only need the first one, can I uninstall somehow both of them and start from the beggining of the latest instructions?
(Thank you for your time!!!)
Sorry, typo … I’ve fixed the command in my last posting
mary … don’t worry if you installed the patch.deb, it won’t hurt to leave it installed … the important thing is that you have the b43-fwcutter package installed, then you install the firmware
ok, the output is:
ii b43-fwcutter 1:015-9
Utility for extracting Broadcom 43xx firmware
On another PC with internet access … download this file (firmware archive):
http://mirror2.openwrt.org/sources/broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
and copy it to the b43 directory you created on the Ubuntu desktop.
Open a terminal, and run these commands in sequence:
cd ~/Desktop/b43
then
tar -xjvf broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
then
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o
then
sudo chmod 755 /lib/firmware/b43
then
sudo modprobe -r b43
(don’t worry if that command fails … just carry on below
then
sudo modprobe b43
Does your wireless spring to life ?
–
omg it works!!! It became alive from the first second after the last command!! 
Thank you soooooooo so much!!! You have to teach me some lessons to learn linux good because I have to know it!!! :P:) haha
You’re most welcome
Might be a good idea to check it survives a reboot.
If it doesn’t let me know and we’ll add the b43 module to be loaded at bootup.
–
It works fine after a reboot!! Thank you so much once again!! You are the best!!
Thanks for letting me know … and you’re welcome again
