Wiil Broadcom Wifi Card work with Garuda?

alex1545 · 28 June 2021 12:29

Just got fresh install of Garuda and cannot get Wifi Card working. Kernel 5.12

It is Broadcom BCM 2045A0 ( I do not see it in supported list - Broadcom wireless - ArchWiki )

In System Settings this card is seen as BCM4350. Then on another line: network-broadcom-wl : Open Source is finked green.

Device-2: Broadcom BCM4350 802.11ac Wireless Network Adapter vendor: Dell driver: N/A  
modules: brcmfmac port: 3000 bus-ID: 04:00.0 chip-ID: 14e4:43a3 class-ID: 0280  
IF-ID-1: anbox0 state: down mac: <filter>

Reading in the forum I see that many people have issues with Broadcom. Should I stop now wasting time
or is there still anything I can do?

Thanks for advice

I really think that there will be a way to help you.
@tbg solved so many issues for Broadcom cards and networking in general
Have you tried some of the many solutions (regardless the model mismatching), e.g. the command here:

I’d also give a look at this one:

It looks like brcmfmac was blaklisted by another driver (in your case this could be network-broadcom-wl).

Thanks for getting back to me.

running

produces following output:

Model: "Intel Ethernet Connection (12) I219-V"
Driver: "e1000e"
Device File: eno1
Link detected: yes
Driver Status: e1000e is active
Driver Activation Cmd: "modprobe e1000e"
Model: "Broadcom BCM4350 802.11ac Wireless Network Adapter"
Driver Status: brcmfmac is active
Driver Activation Cmd: "modprobe brcmfmac"

/lib/modprobe.d/broadcom-wl-dkms.conf is empty for some reason.

running

sudo systemctl stop NetworkManager; sudo modprobe -r wl; sudo modprobe -r brcmfmac; sleep 3; sudo modprobe brcmfmac; sudo systemctl start NetworkManager

freezes compurer and I have to manualy redoot it.
On terminal is says:

modprobe: Fatal: wl not found

filo · 28 June 2021 16:03

What if you simply try:
sudo modprobe brcmfmac

Or if it does nothing, if you try without wl:

sudo systemctl stop NetworkManager
sudo modprobe -r brcmfmac
sleep 3
sudo modprobe brcmfmac
sudo systemctl start NetworkManager

Don't want to waste your time, this is my last attempt

alex1545 · 28 June 2021 16:10

on

sudo modprobe brcmfmac

System freezes. This time nothing in the terminal

Thanks for trying anyway!

Did you try installing

bcm4350-firware

from AUR?

https://aur.archlinux.org/packages/bcm4350-firmware/

alex1545 · 28 June 2021 16:18

Umm, I am new to Arch...which command should I run to do that?

Naman · 28 June 2021 16:20

tbg · 28 June 2021 16:39

That driver will likely be strictly for the Bluetooth component on his wifi/BT combo chip.

I would be testing other kernels such as, linux, linux-lts, and linux-mainline for starters.

You haven't provided your inxi output yet. I'm guessing this is a Macbook?

How could I try other kernels? Thanks

tbg · 28 June 2021 16:51

Garuda Settings Manager contains a utility for installing kernels.

If that doesn't help then download and burn an LXQT-Kwin live ISO and see if your wifi works with Connman.

tbg · 28 June 2021 16:59

Are you trying to run this in a virtualized anbox environment?

Is airplane mode or a hardware switch blocking your wifi?

Please post:

rfkill list

We know your chip is being initialized as your bluetooth is now reported as “up”.

alex1545 · 28 June 2021 17:02

No, this is bare metal.

fkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

tbg · 28 June 2021 17:03

That is a very strange output on your wifi state. I don't ever recall seeing that before.

alex1545 · 28 June 2021 17:14

Successfully installed network-broadcom-wl

Via Settings Manager, yet no wifi. I’ll try LXQT-Kwin live ISO in live mode to see if the card work there…

tbg · 28 June 2021 17:19

So do you have Anbox installed at all on your machine?

The Broadcom-wl driver will only make things more complex to troubleshoot.

I would add the wl driver to the blacklist created in /etc/modprobe.d.

I would then manually modprobe the kernel module.

sudo systemctl stop NetworkManager; sudo modprobe -r wl; sudo modprobe -r brcmfmac; sleep 3; sudo modprobe brcmfmac; sudo systemctl start NetworkManager

Reboot, then you could try running that command again now that the wl module is installed.

alex1545 · 28 June 2021 17:32

There are 3 files in /etc/modprobe.d

rw-r–r-- 0 root 21 Jun 08:26  .gitkeep
.rw-r–r-- 129 root 24 Jun 20:25  mhwd-gpu.conf
.rw-r–r-- 61 root 21 Jun 08:26  nobeep.conf
.rw-r–r-- 76 root 21 Jun 08:26  noime.conf

where should I blacklist it and what is the syntax?

I dont really know what is Anbox…what is the way to check and remove it?

tbg · 28 June 2021 17:37

Do you still have the wl driver installed?

If you installed the wl driver then it should have created a blacklist file for the Broadcom kernel modules, however it is not there.

I am really leaning towards this being a kernel issue.

Try the Garuda XFCE live boot disk as it uses the LTS kernel. You have made a lot of changes and a starting from a clean image may be far better at this point.

alex1545 · 28 June 2021 18:06

This is what is have now in /lib/modprobe.d/broadcom-wl-dkms.conf

blacklist b43
blacklist b43legacy
blacklist bcm43xx
blacklist bcma
blacklist brcm80211
blacklist brcmfmac
blacklist brcmsmac
blacklist ssb

Should I try to remove something?
