[SOLVED] Broadcom Wifi stopped working after update

Pretty  much the title.

According to pacman.log:

upgraded linux-firmware (20221109.60310c2-2 -> 20221214.f3c283e-1)`

Card is

lspci -vnn -d 14e4:

gives

05:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries Device [14e4:43c3] (rev 04)
	Subsystem: ASUSTeK Computer Inc. Device [1043:86fb]
	Flags: fast devsel, IRQ 19
	Memory at 56000000 (64-bit, non-prefetchable) [size=32K]
	Memory at 55800000 (64-bit, non-prefetchable) [size=8M]

	Capabilities: [160] Virtual Channel
	Capabilities: [1b0] Latency Tolerance Reporting
	Capabilities: [220] Physical Resizable BAR
	Kernel modules: brcmfmac, wl

Which should be supported by the brcfmac kernel module. Which is loaded

lsmod | grep brcmfmac

gives

brcmfmac              507904  0
brcmutil               24576  1 brcmfmac
cfg80211             1126400  1 brcmfmac
mmc_core              233472  1 brcmfmac

However firmware is not loaded

dmesg -k | grep brcmfmac

shows

[    7.085441] usbcore: registered new interface driver brcmfmac
[    7.085468] brcmfmac 0000:05:00.0: enabling device (0000 -> 0002)

[    8.074677] brcmfmac 0000:05:00.0: brcmf_pcie_init_ringbuffers: invalid max_flowrings(264)

The failed files are not present

ls /lib/firmware/brcm/ | grep 4366c

only shows

brcmfmac4366c-pcie.bin.xz

Of course the actual symptom is that no wireless interface is created.

ip link show

only displays loopback and ethernet.

I also read on the driver homepage that

Some new devices are storing the nvram which is needed in addition to the firmware by the driver in an EFI variable ...

However /sys/firmware/efi/efivars/ does not contain any nvram-... file.

Any advice would be much appreciated.

Re: [SOLVED] Broadcom Wifi stopped working after update

wl blacklists brcmfmac and no kernel module is in use for the device.

uname -a
pacman -Qs 'linux|broadcom'

Edit: "wl" is maybe not a very narrow match
Please use "broadcom" instead (like in the edited command)

Re: [SOLVED] Broadcom Wifi stopped working after update

Update:

wl module is loaded on startup but I do not know why.

lsmod | grep wl

wl                   6512640  0
cfg80211             1126400  2 wl,brcmfmac

I blacklisted wl by adding /etc/nowl.conf
with content

# Do not load wl module
blacklist wl

Do I need to set any special access rights?

However, no change.

Re: [SOLVED] Broadcom Wifi stopped working after update

There seems no broadcom-wl package installed, do you possibly have the module in the initramfs, but removed the package afterwards?

Re: [SOLVED] Broadcom Wifi stopped working after update

Possible, I did install broadcom-wl when trying to fix the problem. But uninstalled after it didn't help.

Re: [SOLVED] Broadcom Wifi stopped working after update

You'll have to rebuild the initramfs to get rid of it.
That doesn't explain why the NIC isn't used, though.
Check "rfkill" and in doubt post the system journal.

Re: [SOLVED] Broadcom Wifi stopped working after update

LOL just tried to rebuild initramfs and bricked the system. (grub not loading up anymore)
No worries. Will investigate tomorrow with a live stick...

Re: [SOLVED] Broadcom Wifi stopped working after update

I also encountered this issue this morning after upgrading to linux 6.1.4 — uname -a output:

Linux serpent 6.1.4-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 07 Jan 2023 15:10:07 +0000 x86_64 GNU/Linux

I tried installing broadcom-wl.  dmesg -k | grep brcmfmac no longer lists firmware load errors, but sill can't see device.  iw dev and rfkill list both produce nothing.

Here is my dump of journalctl -b.

I suspect it's a problem with 6.1.4 — I had been running linux-firmware 20221214.f3c283e-1 with older kernels and didn't have problems with the wireless until after the kernel upgrade.

Re: [SOLVED] Broadcom Wifi stopped working after update

Jan 11 10:27:52 serpent kernel: wl driver 6.30.223.271 (r587334) failed with code 1
Jan 11 10:27:52 serpent kernel: ERROR @wl_cfg80211_detach : 
Jan 11 10:27:52 serpent kernel: NULL ndev->ieee80211ptr, unable to deref wl

I'm not sure that broadcom-wl can be ecpected to support the device at all (does it w/ the older kernel?)
Do you have a journal w/p broadcom-wl?

Re: [SOLVED] Broadcom Wifi stopped working after update

Here is a journal of an attempt with 6.1.1.  It did not work.  Interestingly, sddm also refused to start.

Here is a journal of 6.1.4 without broadcom-wl.

Re: [SOLVED] Broadcom Wifi stopped working after update

6.1.1 doesn't loead either wl nor brcmfmac (liekly still blacklisted by wl and the out-of-tree wl module doesn't match the kernel if you didn't use the dkms version or downgrade it as well)

6.1.4 has

Jan 11 12:12:04 serpent kernel: usbcore: registered new interface driver brcmfmac
Jan 11 12:12:04 serpent kernel: brcmfmac 0000:07:00.0: enabling device (0000 -> 0002)
Jan 11 12:12:04 serpent kernel: brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4366c-pcie for chip BCM4366/4

Jan 11 12:12:05 serpent kernel: brcmfmac 0000:07:00.0: brcmf_pcie_init_ringbuffers: invalid max_flowrings(264)

which matches the OP

https://bugzilla.kernel.org/show_bug.cgi?id=216894

Sidebar: you've NM and dhcpcd enabled; pick one (likely NM), disable the other.

Does the patch linked by seth [1] resolve the issue?

Re: [SOLVED] Broadcom Wifi stopped working after update

The patched kernel that loqs supplied resolved the wireless problem, but systemd refuses to bring my DM up.

Edit: journalctl dump

Re: [SOLVED] Broadcom Wifi stopped working after update

Unrelated

Jan 11 14:05:23 serpent systemd-modules-load[276]: Failed to find module 'nvidia-uvm'
Jan 11 14:05:23 serpent systemd-modules-load[276]: Failed to find module 'vboxdrv'

Jan 11 14:05:23 serpent systemd-modules-load[276]: Failed to find module 'vboxnetflt'

looks like a dkms issue?
Or partial upgrade?
Or you've an older nvidia module in the initramfs?

If you can't resolve it yourself, start a new thread to keep this one on topic and post the output of

pacman -Qs 'linux|nvidia'
dkms status

@loqs
The packages you postet resulted in a frozen boot sequence for me.
Still no wifi so far...

Re: [SOLVED] Broadcom Wifi stopped working after update

Post a complete system journal (ideally for the "frozen" boot, but otherwise any)
Can you still boot the multi-user.target w/ loqs' kernel? (2nd link below)
