Wireless NIC Broadcom 4312 (b43) is not being installed

Hi folks,

I've got a problem on my HP6735s: Knoppix 7.0 is not installing an appropriate driver for my wireless NIC (Broadcom Corporation BCM4312 802.11b/g LP-PHY). The complete output of lspci -v is attached. iwconfig say 'no wireless extensions'.

The wireless-NIC-LED ist blue, so the device is activated. I've tried http://wiki.debian.org/bcm43xx, but no wireless device appears in the Netzwerk-Manager-Applet.

Any links, docs or howtos appreciated. Thanks for you time.

Regards,
Oliver.

If you issue the command

Code:

cat /boot/config-3.2.4 | grep B43

you will get the lines

Quote:

# CONFIG_B43 is not set
# CONFIG_B43LEGACY is not set

The Knoppix kernel does not support your BCM4312 wireless adaptor. There is no kernel module. Therefore downloading the firmware files and copying them to the proper place in the filesystem as described on the web page you mentioned won't help.

If you read the page "b43 and b43legacy" of the Linux Wireless web site you will find out that there exists a proprietary driver "broadcom-wl" you could try out. Don't forget to read the file README.txt on the Broadcom web page.

I hope that helps.

Greetings, Ekeis & Klaus2008

This is disturbing news, I think.
Make sure you haven't inadvertently blacklisted wl, if that's what you need.

I've been happy with Knoppix since 6.2; I haven't seen 7.0 yet.
I have the BCM4312 and have been using the wl driver all along.
See for example, with my current 6.7.1:

Code:

knoppix@Microknoppix:~$ lspci | grep -i bcm; lsmod | grep wl 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) wl 1936903 0

My wl has always been loaded without any hassle at all. Up til now?

If wl is needed and isn't provided automatically,
the bcmwl source is available via synaptic, BUT
it's a real hassle to install. I've complained about with Ubuntu
and all its clones.

Conversely, if you need b43, make sure that's not blacklisted.

Thanks guys, that helped me out and I solved it. The recipe was:

Get the driver from http://www.broadcom.com/support/802.11/linux_sta.php
For 32 bit: hybrid-portsrc.tar.gz
For 64 bit: hybrid-portsrc-x86_64.tar.gz

Setup dir and untar:
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar or <path>/hybrid-portsrc-x86_64.tar.gz

Patch the driver, download this patch: bc_wl_abiupdate.patch
# patch -p0 src/wl/sys/wl_linux.c < bc_wl_abiupdate.patch
# sudo make
# sudo make install
# sudo depmod
# sudo modprobe wl

Give the driver a little time to scan wireless networks, connect to your network, key in the password and your done.

Thanks and best regards,
Oliver.

@ Ekeis

I'd be interested to know if you tried using Synaptic to bring inthe bcmwl source,
and if so, how that went.
This is what I end up doing with Ubuntu-related distros.

Sorry about this, I forgot to install the broadcom-sta-modules package right after updating the kernel to 3.2.4 in the final version. But you can find the packages here (for both 32 and 64 bit this time!):

http://debian-knoppix.alioth.debian..../broadcom-sta/

If you have the debian-knoppix repository in your /etc/apt/sources.list (which should be the case when running Knoppix 7.0.0), you could also (after connecting to the internet via LAN) just type

sudo apt-get update
sudo apt-get install broadcom-sta-modules-3.2.4
and/or
sudo apt-get install broadcom-sta-modules-3.2.4-64

to get the modules downloaded and installed. For activating the module immediately, type

sudo rmmod bcma
sudo modprobe wl

If you run Knoppix 7.0.0 from USB flash with a persistent overlay, the change will be permanent.

I'll make sure that in the upcoming public release, which will most likely contain the new kernel 3.3 already, the driver won't be missing again.
