Trying to fix Broadcom Wireless driver

Fresh install yesterday. Looked through my syslog to findout that I needed to do this:

Jul 15 06:59:54 StevesDell kernel: [ 12.546770] b43-phy0 ERROR: You must go to and download the correct firmware for this driver version. Please carefully read all instructions on this website.

to replace this:

I was following the directions to replace my firmware for the Broadcom Wireless. Unfortunately, apt-get is interupted (or rather dpkg), for just about anything I try to install. Trying to revert with dpkg ends up in a crash that pops me out of my desktop into a regular fullscreen black/white text screen. I’ll have to take a picture of the screen and when I get my smartphone back from my girlfriend tomorrow.

I’m just curious. Is that just a placeholder driver or just a broken one that we never bothered to take out?

What exactly happens when you say:
“apt-get is interupted (or rather dpkg), for just about anything I try to install.”

Screenshot included as attachment.

It tells me dpkg was interupted. It then advises me to dpkg --configure -a. When I do it, it removes the old bcmwl and rebuilds. After its done it crashes me out of the desktop to a black and white text screen. Unfortunately I can’t take a screenshot of it since I am no longer in the desktop environment and after I reboot I can’t find a log with the message that comes up on the crash screen.

I guess this driver seems not to be compatible with your card. Please remove the package bcmwl-kernel-source.
If your wirless is not working please try the hardware driver manager. It should detect and install the correct driver.

I am not familiar with this package manager. I haven’t messed around with unix/linux for about a decade :stuck_out_tongue: so I may be a little rusty. How do I remove it? I have tried running Driver Manager but this ends up in the same crash. Would the crash screen be of any use to anyone? Is that info logged somewhere?

You can remove it either from muon or using the command line

sudo apt-get purge bcmwl-kernel-source .
If it is stucked in a dpkg --configure -a loop (meaning it says you need to run it but running it would result in a crash) you can forcefully remove it with

sudo dpkg --purge --force-all bcmwl-kernel-source.

I also advice you to install the linux-firmware-nonfree package again either with muon or via command line after purging the bcmwl-kernel-source (otherwise it would not work).

Looks like the dpkg purge command went through. Hopefully this will allow me to install the right ones.

Should I not get the firmware-b43-installer as the log states? What’s the difference between them?

The linux-firmware-nonfree package installs many nonfree firmware drivers hopefully one that’s working with your hardware.
