wlan0 - BCM4312 Wireless Problems on Salix 14.2 [solved]

[_tet_]

On my laptop the wireless card is not working. In the config I see, that the notebook is working with a BCM43142, see:

Code: Select all

sudo lspci -vv | grep Network
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

Buf ifconfig or iwoncig only shows eth0 and lo.

Code: Select all

sudo ifconfig wlan0 up

returns in an error (=wlan0: ERROR while getting interface flags:...).

To load the module brcmsmac

Code: Select all

modprobe brcmsmac

modify the b43_backlist.conf and reboot did not solve the problem

Please help, to get BCM4312 up and running on salix 14.2, 64-bit, xfce.

Thank you

Thank you for the answer.
But it is not working

I am using the standard-Kernel 4.4.19, see:

Code: Select all

uname -r
4.4.19

In /lib/modules/4.4.19 I can that the link is ok, see:

Code: Select all

ls -all
insgesamt 3812
drwxr-xr-x  3 root root   4096 Nov  7 00:50 .
drwxr-xr-x  3 root root   4096 Nov  7 00:38 ..
lrwxrwxrwx  1 root root     21 Nov  7 00:50 build -> /usr/src/linux-4.4.19
drwxr-xr-x 14 root root   4096 Nov  7 00:38 kernel
...

But in /usr/src/ is the wrong build:

Code: Select all

root[src]# ls -all linu*
lrwxrwxrwx  1 root root   12 Nov  3 21:21 linux -> linux-4.4.88

... 4.4.88 instead of 4.4.19

As a result the command

Code: Select all

sbopkg -i broadcom-sta

is running on an error, see:

Code: Select all

patching file src/shared/linux_osl.c
patching file src/wl/sys/wl_cfg80211_hybrid.c
make: *** /lib/modules/4.4.19/build: Datei oder Verzeichnis nicht gefunden.  Schluss.

... So I have to replace the kernel build 4.4.88 with 4.4.19 or migrade the kernel to 4.4.88.

Can you give me a link, to do that ...

The 4.4.88 kernel is now the Salix 14.2 standard so you should upgrade to it. Use slapt-get in a terminal to upgrade. Here's how.

First update the package cache:

Code: Select all

$ sudo slapt-get --update

Then upgrade all the kernel related packages. Assuming that you are using the kerenl-huge kernel, upgrade the five kernel related packages.

Code: Select all

 sudo slapt-get --install kernel-huge kernel-modules kernel-headers kernel-firmware kernel-source

After this and before you reboot, you need to run either lilo or eliloconfig to update the boot loader with the new kernel.

Code: Select all

$ sudo lilo -v 

or

Code: Select all

$ sudo eliloconfig

Great - thank you.

At first I did the Update of the kernel with

Code: Select all

sudo slapt-get --update
sudo slapt-get --install kernel-huge kernel-modules kernel-headers kernel-firmware kernel-source
sudo lilo -v 

After a reboot I checked the kernel with

Code: Select all

$ uname -r
4.4.88

The update was correct

After that I was able to install the driver with

Code: Select all

sudo sbopkg -i broadcom-sta

This time everything was fine.
Then I created the file /etc/modprobe.d/b43-blacklist.conf with the configuration, and rebooted the notebook.
The check with iwconfig was correct:

Code: Select all

$ iwconfig
lo        no wireless extensions.

eth1      IEEE 802.11abg  ESSID:"Nest"  
          Mode:Managed  Frequency:2.442 GHz  Access Point: BC:05:43:F1:16:BB   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          
eth0      no wireless extensions.

eth1 is available

After this it was necessary to configure eth1 in the wicd-client as "wireless lan", searched for wireless lans and configured my network "nest".

Everything is working. Thank you very much.

Another benefit is: also virtualbox is working. When I tried to start the application, I got the error

Code: Select all

The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (4.4.19) or it failed to load.
Workaround at the time: Convert the image with VBoxManage clonehd & then start with qemu-system-x86_64. But it is very slow.

It looks like, that the reason for the error was the difference in Kernel (old 4.4.19) and the kernel module (4.4.48). Now the kernel module are both 4.4.98, and here also everything is working. Thank you.
