BCM4360 - Ubuntu doesn't seems to use the driver

[moi15moi]

I have a Rosewill RNX-AC1300PCE wifi-card which use BCM4360. I installed this package by following the manual instruction in the readme (so the make installation). I rebooted my computer, but ubuntu doesn't recognize my wifi-card like you can see in this screenshot:

I don't know if it is revelant, but I also got some warning when I did a make. I don't know if it change anything:

The README file contains all the instructions

I did the rmmod command for all the modules listed I wrote in the file /etc/modprobe.d/blacklist.conf the same text in the readme. Finally, I followed the instruction for the manual installation (the make installation) Is there something I missed?

Please follow them and share the output of lsmod.

[antoineco]

The wl module was loaded just fine.

If you disable your WiFi interface and re-enable it (e.g. by restarting the network service) do you see any relevant error reported by the dmesg command?

[moi15moi]

The output it too long, so I put it in a text file Output.txt

But, I don't see any apparent error

[antoineco]

The wl module "taints" the kernel according to the logs, but that shouldn't be a blocker.

Possibly the bcma module wasn't blacklisted properly and your device is trying to use it:

[    0.883240] bcma-pci-bridge 0000:04:00.0: bus0: Bus registered

In your original message you wrote:

    Kernel driver in use: bcma-pci-bridge
    Kernel modules: bcma, wl

[moi15moi]

Possibly the bcma module wasn't blacklisted properly and your device is trying to use it:

Here is my /etc/modprobe.d/blacklist.conf file. Like you can see at the end of it, I wrote blacklist bcma, so I guess it should be good, no?

moi15moi@moi15moi-System-Product-Name:~$ cat /etc/modprobe.d/blacklist.conf

Let's check a few things:

1. Blacklisted entries are only considered after a reboot. Did you reboot?
2. To unload modules which were already loaded, you have to call rmmod (with sudo). But since you said you already did it, I'm not sure what the problem could be. Are you certain that sudo rmmod bcma returned without error?
3. Maybe check your /etc/modules file and ensure that there is no bcma entry in there? (or any of the other blacklisted modules)

[moi15moi]

• Blacklisted entries are only considered after a reboot. Did you reboot?

Yes, I did reboot.

• To unload modules which were already loaded, you have to call rmmod (with sudo). But since you said you already did it, I'm not sure what the problem could be. Are you certain that sudo rmmod bcma returned without error?

It doesn't print anything when I run sudo rmmod bcma. Is that a good sign?

3. Maybe check your /etc/modules file and ensure that there is no bcma entry in there? (or any of the other blacklisted modules)

I don't have a folder named /etc/modules. I verified all the file in /etc/modprobe.d/ and none of them (except of course blacklist.conf) blacklist bcma.

[antoineco]

/etc/modules is a regular file. If you don't have any, all good.

What happens if you rmmod wl and modprobe wl again? As before, please check dmesg for clues and verify with sudo lspci -vnn -d 14e4 what driver is in use.

[moi15moi]

Here is the output of these command (I runned all of them has root): Output.txt

It seems to be pretty much the same has the previous output I share of those commands

[moi15moi]

I found a solution.

I runned the command sudo update-initramfs -u (I saw the solution here) and rebooted. Now, it doesn't ignore the blacklist for bcma.

I can now connect to my local router.

It may be a good idea to mention it in the Readme. What do you think?

[moi15moi]

Strange, I just rebooted and now, ubuntu detect my wifi-card, but it cannot anymore connect to my wifi. It can see my wifi, but when I try to connect to it, it load indefinitely

When I boot, I need to forget the wifi and restart the network because it won't connect to my router via sudo systemctl restart systemd-networkd. Also, it seems that the wifi only work for a few minute and then, it deconnect from the wifi (but ubuntu still can see the wifi)

[antoineco]

Interesting, I had never heard of the blacklist file being in the initramfs before. If that's a standard thing on Ubuntu I should definitely mention it indeed.

I have personally not experienced instabilities of that sort, but dmesg will show you any error relating to the wl module.

[antoineco]

I see that the Debian package is doing exactly what you did upon installation: https://salsa.debian.org/broadcom-sta-team/broadcom-sta/-/blob/debian/debian/broadcom-sta-common.postinst (learned something!)

They are also blacklisting a few extra modules, maybe you should try that as well: https://salsa.debian.org/broadcom-sta-team/broadcom-sta/-/blob/debian/debian/broadcom-sta-common.modprobe

Side question: since Ubuntu also has this package, why not simply install it? This would save you the effort of re-building the module on every kernel update, or setting up dkms manually.

[moi15moi]

I have personally not experienced instabilities of that sort, but dmesg will show you any error relating to the wl module.

Here is the output: output.txt It says [ 3.961427] wl: module verification failed: signature and/or required key missing - tainting kernel

Side question: since Ubuntu also has this package, why not simply install it? This would save you the effort of re-building the module on every kernel update, or setting up dkms manually.

Because I'm too far from my router to use an ethernet cable.

They are also blacklisting a few extra modules, maybe you should try that as well: https://salsa.debian.org/broadcom-sta-team/broadcom-sta/-/blob/debian/debian/broadcom-sta-common.modprobe

I tried, but it doesn't correct the problem.

[antoineco]

From the kernel logs alone, everything is looking fine to me:

[    3.967072] wl 0000:04:00.0: enabling device (0000 -> 0002)
[    4.038135] wlan0: Broadcom BCM43a0 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)
[    4.199668] wl 0000:04:00.0 wlp4s0: renamed from wlan0

When I boot, I need to forget the wifi and restart the network because it won't connect to my router via sudo systemctl restart systemd-networkd.

That is more of an OS configuration issue than a kernel module issue. I don't have enough information to help here, but it could be that the network is managed through the NetworkManager service (one level on top of systemd).

Also, it seems that the wifi only work for a few minute and then, it deconnect from the wifi (but ubuntu still can see the wifi)

If it works and then disconnects without emitting any kernel message, it means that the issue isn't caused by a failure of the kernel module. In case I was right about NetworkManager being in charge of the network on Ubuntu, I would suggest checking the journal logs of that service around the time the network disconnected.

[moi15moi]

At 9:32, the wifi work, but from 9:36, it automatically disconnect

Here is the output of sudo journalctl -fu NetworkManager : output.txt

[moi15moi]

I found the problem. It was my fault.

In brief, I just needed sudo update-initramfs -u to correct my problem.
