WLAN firmware not installing

[namda]

I have a Broadcom wireless interface and know that I need the b43 firmware. I followed the instructions on the debian website both for the regular install and for the fwcutter. Neither of them installed the firmware files to /lib/firmware/

I am not sure what to do from here. Can anyone help? Thanks

Please show us -

Code: Select all

lspci -nnk | grep -iA2 net
modinfo b43
ls /lib/firmware/b43/*

You may have to run one or more of the above commands as root to get output.

Neither of them installed the firmware files to /lib/firmware/

Did you notice any errors during either processes? Anything significant that you remember?

You could try either firmware-b43-installer or firmware-b43legacy-installer depending on the card you have.

V&N, here is the output of the commands you told me to run. I did not include anything that has to do with my ethernet card.

sudo ls /lib/firmware/b43/*

Code: Select all

ls: cannot access /lib/firmware/b43/*: No such file or directory

I do not remember any sort of error when it was installing.
I ran

Code: Select all

sudo apt-get install firmware-b43-installer

and it seemed to have done what it was supposed to. Is there something I have to run after that?
Thanks

Just reboot.

[namda]

Dai_trying, the issue is that the firmware installer does not seem to be installing the firmware files. Rebooting would not help in this case.

I thought this meant that it had installed the firmware successfully?? My mistake...

[namda]

Dai_trying ok. Just a little misunderstanding there.

I have the same card in my old Dell Inspiron 32 bit machine, I can zip up the b43 folder and post it somewhere for you if it will help.

Please run the command again, and post its complete output.

Yes it will definitely help, and so will extracting and copying the same files from this ubuntu package : https://packages.ubuntu.com/trusty/linu ... re-nonfree

But I'd recommend to try the official method first, so we can find out if it could be some bug to be reported.

Ok so I figured it out. When I went to install the firmware package I was not being observant and did not see that the firmware came up with a message. It basically said to install a different package because I have a low power wifi card. I did that and now it works. Thanks for the help from those who responded!

That is exactly what I was anticipating, but wasn't sure as the description of 'firmware-b43-installer' mentioned that it did support BCM4312 (LP).

It would make this thread much more useful if you could share with us the exact package name you finally succeeded with.
