RESOLVED: Broadcom Wireless Network Card "UNCLAIMED"

[RagingBullDurham]

I installed LMDE 6 Faye on my laptop (Linux Kernel 6.1.0.12-amd64) and my wireless network is not visible/working. (Worked perfectly after LMDE 5 install)

My wireless card:

Code: Select all

 $ lspci -nn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01) 

UNCLAIMED Status.

Code: Select all

$ sudo lshw -C network
***
  *-network UNCLAIMED
       description: Network controller
       product: BCM4313 802.11bgn Wireless Network Adapter
       vendor: Broadcom Inc. and subsidiaries
       physical id: 0
       bus info: pci@0000:02:00.0
       version: 01
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress cap_list
       configuration: latency=0
       resources: memory:f7d00000-f7d03fff

From this article (seems to be pretty up to date), I'm learning that my card should be installed by default:

14e4:4727 rev 01 Special Case #1/firmware-b43-installer:
Special Case #1 - Uses bcma and brcmsmac driver combination. Required firmware is installed by default in the package linux-firmware.

But it looks like linux-firmware is not on my system nor available:

Code: Select all

$ sudo apt install linux-firmware
...
E: Unable to locate package linux-firmware

And I can't figure out what repository to add to get access.

Please help me get my wireless network card to work (like it did w/ LMDE5)

[JeremyB]

Try in terminal

Code: Select all

sudo apt update && sudo apt install firmware-brcm80211

Reboot

[RagingBullDurham]

No Joy:

Code: Select all

$ sudo apt update && sudo apt install install firmware-brcm80211
...
E: Unable to locate package install

[sleeper12]

It might help us to see more details. Post what this shows:

Code: Select all

 inxi -Fxxxrz ; rfkill list ; iwconfig ; mokutil --sb-state 

[JeremyB]

No Joy:

Code: Select all

$ sudo apt update && sudo apt install install firmware-brcm80211
...
E: Unable to locate package install

I had a typo

Code: Select all

sudo apt install firmware-brcm80211

[RagingBullDurham]

Looks like I already have this...

Code: Select all

$ sudo apt install firmware-brcm80211
...
firmware-brcm80211 is already the newest version (20230210-5).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Again, according to this article I need to only install "linux-firmware" package - but

Code: Select all

$sudo apt install linux-firmware
...
E: Unable to locate package linux-firmware

THIS WORKED!!!! - HOW THE HELL DID YOU KNOW? AND WHY WOULD SECURE BOOT LET ME DO EVERYTHING EXCEPT SEE MY NETWORK CARD - THANK YOU!
(this post submitted via my working wireless network card)

[JeremyB]

If you were using broadcom-sta-dkms the module isn't signed and the kernel won't allow the driver to load with Secure Boot enabled
I had the same card and it worked with the normal kernel drivers with the broadcom firmware

[sleeper12]

Also, disable secure boot in Bios.

SLEEPER12:

(this post submitted via my working wireless network card)

I just knew that secure boot can cause wifi problems. Didn't know if it would solve the issue, but glad it did.

[RagingBullDurham]

using broadcom-sta-dkms the module isn't signed

Any way to get/use a signed version of broadcom-sta-dkms???

[JeremyB]

I would uninstall it and see if the kernel modules bcma and brcmsmac work like they did for me
The instructions you found were Ubuntu specific, LMDE uses different firmware packages

[RagingBullDurham]

Interested in this option

I would uninstall it and see if the kernel modules bcma and brcmsmac work like they did for me

Uninstall easy:

Code: Select all

$ sudo apt remove broadcom-sta-dkms

Works fine. BUT

Code: Select all

$ sudo apt install bcma
...
E: Unable to locate package bcma

- same for brcmsmac

I obviously don't know what I am doing. How do I install bcma and brcmsmac?

[JeremyB]

Those are kernel modules, you already have them. Reboot and then

if this is still actual, you need to load module first

Code: Select all

sudo modprobe brcm

or to load module on boot create file /etc/modules-load.d/brcm.conf containing one line: brcm
