Can't get wifi Broadcom BCM4352 to work

Trying to get qubes going, but I can’t get wifi to work. Have Debian 11 as a template for sys-net

Kernel modules was just bcma which doesn’t work with BCM4352 so i manually transferred broadcom-sta-dkms_6.30.223.271-17_all.deb (and a ton of it’s dependencies) and installed them all dpks -i to the template Debian 11 (side not, thought exposure to network drivers should be limited to sys-net, but if i have to install them at Debian template won’t all qubes based on it will be compromised?)

dpks -I broadcom-sta-dkms_6.30.223.271-17_all.deb

 Description: dkms source for the Broadcom STA Wireless driver
  Broadcom STA is a binary-only device driver to support the following IEEE
  802.11a/b/g/n wireless network cards: BCM4311-, BCM4312-, BCM4313-,
  BCM4321-, BCM4322-, BCM43142-, BCM43224-, BCM43225-, BCM43227-, BCM43228-,
  BCM4331-, BCM4360-, and BCM4352-based hardware.
  .
  This package provides the source code for the wl kernel modules and makes use
  of the DKMS build utility to install them for the running kernel. The
  alternative package broadcom-sta-source can be used instead in case of build
  problems.
  .
  The wireless-tools package is also required in order to make use of these
  modules. Kernel source or headers are required to compile these modules.

so after installing wifi still is not found

(sys-net) lspci

...
	Capabilities: [ac] Express Endpoint, MSI 00
	Kernel modules: bcma, wl

and i’m seeing the following error

(sys-net) dmesg | grep wl

kind of makes sense that it’ll be tainting template kernel, so how should this be handled?

Did you try fedora-36 based sys-net?

Nope, first time trying Qubes so went with the defaults. But as far as i know there are no open source drivers for this wifi card, so even in fedora i’d still have to install proprietary drivers

After wasting more time on this Debian wiki says i also need to
apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,')
but it fails because it cannot find qubes kernel version

Good question. Yes, they will.
That is why many people will clone the template:
qvm-clone debian-11 debian-11-broadcom
and then install those extras in to the cloned template.

You can adjust the kernel for a qube on the Advanced Tab in qube
settings.
If you set the kernel there to the same as dom0 you will get the headers
available.

In this sort of case you can set the qube to use the native kernel.
If you set that to “None” then the qube will boot with the native kernel
and you can install native headers.
This may be more what you need.

There’s advice in the docs

I never presume to speak for the Qubes team.


When I comment in the Forum or in the mailing lists I speak for myself.

Hi @fwo7hwwv,
Did you mange to get this working? I’m also facing the same issue with release 4.1. I created a clone from debian-11 template and installed the broadcom-sta-dkms as described in the wiki here wl - Debian Wiki

I’m using the debian linux headers

linux-headers-amd64 is already the newest version (5.10.140-1).
linux-image-amd64 is already the newest version (5.10.140-1).
broadcom-sta-dkms is already the newest version (6.30.223.271-17).

After the installation the bcma still shows up. Running lspci -v returns

I tried to follow the troubleshooting according to debian wiki. find /lib/modules/$(uname -r)/updates returns

/lib/modules/5.10.0-18-amd64/updates
/lib/modules/5.10.0-18-amd64/updates/dkms
/lib/modules/5.10.0-18-amd64/updates/dkms/wl.ko

I also executed

sudo modprobe -v -r b44 b43 b43legacy ssb brcmsmac bcma
sudo modprobe -v wl

After all that wifi is still not working. lspci -v still shows the same as above.

Thanks!

Hi @unman,
I’m facing the same issue. The card works fine in a Ubuntu installation and with windows 10 on the same hardware setup. So I tried to install Ubuntu Desktop in a standalone VM and installed the thirst party Broadcom drivers. But still wifi card is not recognized.
dmesg | grep wl

I also created a windows qube and installed the Broadcom windows driver. Still the card is not working in windows neither. Do you have any idea what can I do to fix this?

Thanks!

A wild guess this might help…

Hi @enmus, thanks for the suggestion. I’m running on a desktop setup with Asus i97z plus motherboard I don’t have TLP installed.

Hi,

did you managed to get it working?
I’m experiencing exactly the same issue.

Hi @digeat, unfortunately no. I had to use LAN connection.
