BCM43143 usb wifi card issues

General system Kernel, boot, graphics & hardware

Yes…check /etc/modprobe.d/modprobe.conf

24

That file does not exist

25

Check just the /etc/modprobe.d

26

There is one file. Blacklist.conf. In it, blacklist b43

27

You can try commenting it out or removing it from blacklist.

28

Already tried that

29

Hmm? I’m not sure what else to suggest?

Edit: Check this

https://wiki.archlinux.org/index.php/Kernel_module#Automatic_module_loading_with_systemd

30

Do you know what deny-listed Means?

31

Did you check usr/lib/modprobe.d it may have the same module listed and then it blacklists when loading. So it could have wl in it?

Edit: or b43

32

Check this:

journalctl - b | grep brcmfmac

Edit: Actually maybe it should be this

journalctl - b | grep b43

33

So if it’s the b43 being blacklisted…that is the firmware.

34

Ugh. Thank you! I got it :slight_smile: I had to remove wl. Sorry for being so clueless :frowning:

35

Well i was wondering if it automatically was blacklisting it because it’s already a kernel module that loads.

So to recap. If anyone has any issues with a Broadcom wifi card using the brcmfmac driver, you may need to remove Broadcom-wl-dkms completely.

No problem sometimes it’s difficult to figure these things out.

I have (had) the exact issue here on my intel iMac.
I removed the package [ broadcom-wl-dkms ] as suggested here and this solved my issue as well. Thank You.

$ lspci -vnn -d 14e4:
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)

— Removed the package broadcom-wl-dkms —
pacman -Ss broadcom-wl-dkms
community/broadcom-wl-dkms 6.30.223.271-28
Broadcom 802.11 Linux STA wireless driver

Thank you very much.

EDIT: This was a fresh installation of endeavourOS.
