Broadcom PCIe Wifi adapter 4366c not working after update

[warlord0]

Wifi card is an Asus with broadcom chipset. It was operational and operating at 802.11ac speeds on kernel 5.19 and 6.1. I then did an update and the card disappeared from my nics.

I got this in my dmesg:

[    0.699145] pcieport 0000:00:1b.4: DPC: error containment capabilities: Int Msg #0, RPExt+ PoisonedTLP+ SwTrigger+ RP PIO Log 4, DL_ActiveErr+

[    3.867786] brcmfmac 0000:05:00.0: Direct firmware load for brcm/brcmfmac4366c-pcie.txt failed with error -2

The file brcm/brcmfmac4366c-pcie.txt does not exist anymore.

I then gave the broadcom-wl a try, and even broadcom-wl-dkms. I think I’m off down a rabbit hole, as these don’t work for me. Trying to roll back, it appears I can’t as the missing text file in the driver above won’t let me.

Next I thought I’d go for a 5.15 LTS kernel and that doesn’t work either. I can’t get back to 5.19 as that’s no longer available.

As much detail as I have collected so far.

Check to see if they are blacklisted in /etc/modprobe.d/

[warlord0]

Thanks for the reply.

My understanding is that the broadcom-wl package blacklists all the other broadcom drivers like b43, hence the message as you install to remove them:

$ sudo rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb tg3 wl 

• That said, there is no blacklist in modprobe.d that I can see.

This also adds to the difficulty in going back to the brcm43xx driver. Although I could remove the broadcom-wl the missing txt file for the brcm43xx means no going back.

[jrichard326]

Is b43-fwcutter installed?
Is this AUR package a possibility?

https://aur.archlinux.org/packages/brcm43xx-firmware

[warlord0]

That may be what was originally installed.

I even extracted the content and there’s no txt file matching the error inside the file either.

I think it’s related to this post from Arch [SOLVED] Broadcom Wifi stopped working after update / Kernel & Hardware / Arch Linux Forums so I may have to wait on a repaired kernel.

In the meantime, I’ve ordered an Intel ax210 card to see if I have any luck with that.

There seems to be two things that kill Linux - broadcom and nvidia, and I have both

[warlord0]

Well, the AX210 turned up, and it plugged in and just works. It even has the same device name, same slot, I guess.

But it’s half the speed of the Broadcom. I’m seeing 160Mbps with the Intel, when I recorded 296Mbps with the Broadcom, but I know I got way faster - just not recorded. I’m guessing the Broadcom being mimio 4x4 and the Intel only 2x2.

For now, it works, but I’ll keep an eye on the Broadcom situation and will probably swap back.

I don’t have Wifi 6 802…1ax and only 802.11ac - so the ax210 is capable of using a newer network, but the older was just fine with me.
