[Solved] BCM4311 driver is not loaded automatically at boot

[patcan]

Hello everybody, just my first touch with linux , so I hope I don't bore anyone .
I have an old hp530, Intell celeron 32 bit, incremented to 2Gb memory, where i installed LMDE:

Code: Select all

patrizio@patcan:~$ cat /etc/os-release
"PRETTY_NAME="LMDE 5 (elsie)"

Unfortunately wifi was not recognized at first installation: lshw (just wifi)

Code: Select all

"*-network UNCLAIMED

looking around I found a good tip :

Code: Select all

sudo apt-get remove --purge bcwl-firmware-kernel-souce
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

it works and now I have blu light on:

Code: Select all

but at reboot i need to load driver by terminal so I followed an other tip :

Code: Select all

sudo su 
echo b43 >> /etc/modules 

now module is correctly reported :

Code: Select all

patrizio@patcan:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

b43
b43
wl

but I still need to load the module by terminal if I want wifi activated.

Any suggestion and explanation why the /ect/modules seems not be loaded at reboot ?
Many thanks Patrizio

Buona sera , grazie Paolo, quando mi sono inscritto la pagina mi ha riportato nella parte inglese ed ho pensato che in relatà i forum fossero tradotti ,perdonate.
Sono un neofita linux, ho appena iniziato ed ho ancora un po di confusione.
Cortesemente ho un vecchio portatile :hp 530, Intel Celeron , con 2Gb di memoria ram su cui ho installato LMDE:
patrizio@patcan:~$ cat /etc/os-release

La scheda di rete non e' stata riconosciuta : comando lshw (riporto solo la wifi) :
*-network UNCLAIMED

vendor: Broadcom Inc. and subsidiaries

clock: 33MHz
capabilities: bus_master cap_list
configuration: latency=0
resources: memory:f0000000-f0003fff

Ho fatto un po di ricerche ed ho trovato una soluzione :
sudo apt-get remove --purge bcwl-firmware-kernel-souce
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

La spia di rete si e' accessa ed al comando : lshw

resources: irq:17 memory:f0000000-f0003fff

Purtroppo al reboot il modulo non sale, devo inserirlo io a mano, quindi ho fatto altre ricerche ed ho trovato questo suggerimento :
sudo su
echo b43 >> /etc/modules
adesso ho :
patrizio@patcan:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

b43
b43
wl

Ma al reboot il modulo continua a non installarsi-
Ho cercato di orientarmi nel filesystem ed ho trovato che nel file modprobe.d ho il brodcom-sta-dkms.confic
che riporta :
# wl module from Broadcom conflicts with the following modules:
blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
mentre il dkms.confi e' vuoto.

potete suggerirmi ed aiutarmi a capire come fissare il problema ?

Grazie Patrizio

sudo apt install broadcom-sta-common broadcom-sta-dkms
Upon reboot the required broadcom wireless kernel module for your currently installed kernel will be built and loaded.

Hello JWZ, thanks for your suggestion but it didn't work.
Actually I have already updated the package ;
sudo apt install broadcom-sta-common broadcom-sta-dkms
Lettura elenco dei pacchetti... Fatto
Generazione albero delle dipendenze... Fatto
Lettura informazioni sullo stato... Fatto
broadcom-sta-common è già alla versione più recente (6.30.223.271-17).
broadcom-sta-dkms è già alla versione più recente (6.30.223.271-17).
0 aggiornati, 0 installati, 0 da rimuovere e 0 non aggiornati.
Thank you

[JeremyB]

Remove those packages

Code: Select all

sudo apt remove broadcom-sta-common broadcom-sta-dkms

Reboot
Then post result from terminal for

Code: Select all

grep [[:alnum:]] /etc/modprobe.d/* | grep b43

[patcan]

Hello Jeremy , thanks to back to me ,
I removed the brodcome package , maybe could be interesting following string :

-------- Uninstall Beginning --------
Module: broadcom-sta
Version: 6.30.223.271
Kernel: 5.10.0-12-686 (i686)
-------------------------------------

Status: Before uninstall, this module version was ACTIVE on this kernel.

wl.ko:
- Uninstallation
- Deleting from: /lib/modules/5.10.0-12-686/updates/dkms/
- Original module
- No original module was found for this module on this kernel.
- Use the dkms install command to reinstall any previous module version.
I did reboot and in order to have wifi I need to type sudo modprobe b43 on terminal .

Following what required :
grep [[:alnum:]] /etc/modprobe.d/* | grep b43
/etc/modprobe.d/broadcom-sta-common.conf:blacklist b43
/etc/modprobe.d/broadcom-sta-common.conf:blacklist b43legacy
/etc/modprobe.d/broadcom-sta-dkms.conf:blacklist b43
/etc/modprobe.d/broadcom-sta-dkms.conf:blacklist b43legacy

Maybe can be interesting to know we have in folder modprobe.d
two files :

Brodcom-sta-common.config
Brodcom-sta-dkms.conf

On both we have :
# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS (this is only in common.conf)

Thanks

[JeremyB]

Code: Select all

sudo rm /etc/modprobe.d/broadcom-sta-common.conf
sudo rm /etc/modprobe.d/broadcom-sta-dkms.conf
sudo rm /etc/modprobe.d/Brodcom-sta-common.config
sudo rm /etc/modprobe.d/Brodcom-sta-dkms.conf

Reboot

Hello Jeremy,
many thanks , now wifi works at boot time.
Pls do you suggest me to remove the linux-firmware-nonfree and try to install again
broadcom-sta-common broadcom-sta-dkms?
Have good time , I am going to active the solved flag.

[JeremyB]

Don't do anything since it works now. The broadcom-sta-dkms and others don't work with your wifi and installing them will prevent the b43 driver from loading
