Hi!

I have installed Ubuntu 11.04 on my laptop. For some reason Wireless Network does not work any more (there was installed 9.04 before).

lspci says:


00:06.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link)
System->Administration->Additional Drivers doesn't list anything.

Can anybody help me? Thanks for any suggestions,
Martin

download this file http://www.omattos.com/sites/default/files/b43-all-fw.tar_.gz

Then transfer it over to your Ubuntu box

Now in your Ubuntu Box [computer] please make your way to your Home folder

Once you are at your home folder right click on your home folder and make a new folder and call it Wireless

Now that you have made a new folder called wireless in your home directory. It is time to move the downloaded file into the new folder called wireless
http://img850.imageshack.us/img850/4563/screenshot1kl.png






Next we need to move that folder to the firmware directory to do this open your terminal and type in

sudo cp -r ~/Wireless/* /lib/firmware/
http://img101.imageshack.us/img101/5329/screenshot5ei.png






Now lets double check to make sure the download made it to the firmware directory. Too do this type this into the terminal

ls /lib/firmware
Do you see it there ? Good if not it did not moved. Go back to the last step and try again. But if you do see it lets move on to the next step
http://img151.imageshack.us/img151/5092/screenshot3ln.png





Ok so now that the download is in the firmware dir we are going to have to go there. To go there open your terminal and type in.

cd /lib/firmware
Now that you have moved lets double check to make sure this next code tells us where we are in the computer file dir. This next code stands for "print working directory"
pwd are you at /lib/firmware if so good if not go back one step
http://img143.imageshack.us/img143/3945/screenshot4zv.png





Now that we are in the firmware directory. We have to extract the download to do this type in

sudo -s then enter your password then

tar -xzf b43-all-fw.tar_.gz
then

exit

Now it is time to reboot

sudo reboot

Do you have wireless now ? If you have any trouble just post

I just wanted to say thank you, thank you, thank you! I had the same problem with a Gateway laptop I'm running and your instructions worked like a charm!

I have had the same problem and solved slightly differently since I had no Ethernet connection available. http://ubuntuforums.org/showthread.php?t=1790338 .

I now have reached the router, in fact I seem to be picking up 6-7 local sites. I have authenticated myself with my site but I am unable to actually reach the internet. The connection is actually working as I can access it from the Windows 7 side of my double boot machine.

I'm an almost complete linux newbie and not much better on wireless accces. Any suggestions that I might try?

Thanks

Are you sure the pci # is [14e4:4135]

Please run in terminal and post results:


lspci -nn | grep 0280

It is best to just copy the command in the box and paste in the terminal. Then hit return. Copy terminal results and paste here...
I hope Broadcom has not got a new pci with that number..
[14e4:4315] we can deal with.

Ok what version of Ubuntu are you running?

cat /etc/lsb-release; uname -r

We can probably go to Synaptic and install
b43-fwcutter
firmware-b43-lpphy-installer

If you have tried the STA (wl) remove
bcmwl-kernel-source

I am running 11.04
I tried using the file that was posted at the beginning of this thread but it wasn't working. I followed the instructions as they were posted. I haven't tried the other thing but, I don't know how. I just installed this today. So, I'm as new as new gets. Thanks for helping and understanding.

Let try something simple

Go to Synaptic PacKage Manager
Do a search on bcm
you should see
b43-fwcutter
firmware-b43-<<<<< see above
Choose those to install .. and apply

You are running Unity Desktop correct?

Just look for Applications in the left hand panel..
Under Installed see move click on that little button
Scroll down to Synaptic (type in password if asked
then search box put in bcm
then select to install
b43-fwcutter
firmware-b43-lpphy-installer
Apply
Reboot without ethernet cable attached set up wireless

Sorry, I've been away for a couple days. I went to synaptic package manager. Searched "bcm" the only thing that came up was "libklibc"

I have b43-allfw.tar_.gz saved in a folder marked wireless. Because I don't have access to the internet from my laptop, I have to download and transfer all files from my netbook which is running an earlier version of eeebuntu.

I followed all of Josephmills steps and I got an error at "tar -xzf b43-all-fw.tar_.gz". The file is now called "all.tar", and doing "tar -xzf all.tar" did not work. However, I did do "tar -xvf all.tar" and that worked. However, nothing changed after I rebooted. Any help?

Thank you :)

When I get to the part of placing the folder in the firmware directory, I type the command in and it prompts me for my password, which will not show; only a flashing white box. Help me please ;)

It worked. I had something wrong with the folder; renamed the folder and it worked :)
