Arch linux wifi broadcom

Arch Linux

Hey,
I am a newbie, or rather an Arch-newb. Booted the iso live, only to see that it does not show the card. Tried using rfkill, tried installing b43 drivers from AUR, installed NetworkManager, broadcom-wl, broadcom-wl-dkms, searched through the entire internet, but none of them seem to work. The most fascinating stuff, though is that I have Garuda Linux installed (drivers initially did not work though) but synced the repositories, rebooted the system and the network card just magically worked.
I also tried doing the same with arch linux but in vain. Copied Garuda Linux drivers to Arch Linux but still did not work.
Is this dependent on the kernel installed?

Wifi Network card: Broadcom BCM43142
Linux kernel of Garuda Linux: Linux-zen

If I do need to post any output, let me know.
iw dev does not show any output, but works on Garuda Linux.

I shall never come to like this laptop, for it smells of burnt GPU

Re: [SOLVED] Broadcom Wifi network card not working

lspci -k dmesg | grep -iE 'wl|b43' ip addr

Also with which exact command did you try to connect? Chances are that the wl driver does not support the newer interfaces used by iwd/iwctl and you might have to opt for wpa_supplicant/nmcli or so,

Re: [SOLVED] Broadcom Wifi network card not working

@V1del, sorry for replying back late, just got back home from work.
ATM, I do not have arch installed. Was frustrated with it and deleted it.
However, I can let you know the output of the commands.
lspci gave:

 01:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01) Subsystem: Dell Device 0018 Kernel driver in use: wl Kernel modules: bcma, wl 

(Something similar to this)
ip addr just showed the loopback interface.

Oh also, I tried wpa_supplicant and nmcli but there was no wifi adapter found.

(Something similar to this)

Is not going to be sufficient. If you want to know why it doesn’t work on arch you’ll have to provide the information from that system, but using the zen kernel you’ll need https://archlinux.org/packages/communit … m-wl-dkms/ to use the wl kernel module (and the https://archlinux.org/packages/extra/x8 … n-headers/ )

Re: [SOLVED] Broadcom Wifi network card not working

@seth, about the zen kernel, it is not the kernel that I use for arch linux. I think it is the LTS version of kernel. The zen kernel is used only for my Garuda Linux OS.

Thanks for the tip tho; I’ll see about copying the text code although IDK how

Re: [SOLVED] Broadcom Wifi network card not working

So, I just ran the commands.

 01:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01) Subsystem: Dell Device 0018 Kernel driver in use: bcma-pci-bridge Kernel modules: wl

Re: [SOLVED] Broadcom Wifi network card not working

Try explicitly reloading wl instead of bcma

modprobe -r bcma wl modprobe wl

Re: [SOLVED] Broadcom Wifi network card not working

@V1del, sorry for the late reply, just ran the two commands above and nothing changed. Ran ping test, but gave «Temporary failure in name resolution». No outputs.

Also, this is something I noticed, but the kernel driver used in Arch Linux is bcma-pci-bridge while Garuda Linux uses wl drivers. Is there something that has to do with it?

Thank you

Re: [SOLVED] Broadcom Wifi network card not working

Yes, you don’t have the wl driver (properly) installed and there’s no working driver for the chip (hence the bcma-pci-bridge module, which is not a broadcom wireless driver)
I guess the b43/bcma drivers are blacklisted by the wl package, but the module doesn’t fit the kernel.
Please post the verbatim outputs of

uname -a pacman -Qs broadcom lsmod modinfo wl | head

Re: [SOLVED] Broadcom Wifi network card not working

In a similar problem of mine with a BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) , it was necessary to blacklist the modules bcma brcm80211 brcmsmac through /etc/modprobe.d/
The choice rmmod / modprobe (as terminal command) has no result for this chipset. There is a big conflict with the modules.
For example you can try to blacklist the modules bcm43xx ssb b43 b43legacy ndiswrapper brcmfmac bcma brcm80211 brcmsmac, all of them or one by one .

Re: [SOLVED] Broadcom Wifi network card not working

Properly unloading all the relevant modules «should» work but I’m not entirely certain on all the modules involved here. The problem is that the problem starts on the live disk and any blacklist you define would not persist, an option to ensure they are blacklisted would be using the command line. I was also under the impression the live disk should already blacklist the non-wl modules

Re: [SOLVED] Broadcom Wifi network card not working

Update: I have just installed arch linux so that things can get easier for me as well as y’all. Thanks for helping out!

Also @seth, will post the output for the commands in a lil later

@V1del, I forgot to mention, the reply you mentioned:

Try explicitly reloading wl instead of bcma

modprobe -r bcma wl
modprobe wl

Unloaded these kernel drivers and tried to load back wl but received a ‘FATAL’ message, saying that the driver (or module?) was not found at a specific location. Would you like me to post the full error message?

Thanks for the replies, hope y’all have a good day

Re: [SOLVED] Broadcom Wifi network card not working

Also, @giannis-arch, good to know that information. Let me give it a try

#14 2022-02-23 09:54:12

Re: [SOLVED] Broadcom Wifi network card not working

Please always post all the outputs you get in full for everything, otherwise if you blankly state «doesn’t work» we don’t know whether that was due to an error in your execution of the command, an error in general, or whether it might be an outright incompatibility that we can’t do much about.

Based on what you mentioned it sounded like the commands went through successfully but you still didn’t get an interface allocated, which is an entirely different issue to look at than outright failure to load the module.

Note that if you actually installed the system now you need to explicitly install the broadcom-wl package it isn’t going to be inherently part of your installation, that package should in turn already have all the proper blacklists. In doubt post the outputs seth asked for in #9

Re: [SOLVED] Broadcom Wifi network card not working

Hello,
I am sorry for not being able to respond since I was figuring out how to paste the output of arch linux here. I also reinstalled arch linux.

During live installation boot, I notice something very unusual:
Bluetooth: hci0 : BCM: Firmware patch not found, tried
Bluetooth: hci0 : BCM: BCM43142A0-(something that I could not observe)
Bluetooth: hci0 : BCM: (and then some more. If I can «pause» the boot screen please let me know)

@seth As per your request, I have posted the outputs for the following:

 Linux shamarch 5.16.11-arch1-1 #1 SMP PREEMPT Thu, 24 Feb 2022 02:18:20 +0000 x86_64 GNU/Linux 

gives absolutely nothing, and I mean it this time.
