New Broadcom board slow wifi

OK, so according to what I’ve seen online, the correct driver for the adapter, is wl. But it’s not in use here:

So all I can recommend is blacklisting the current module:

sudo echo "blacklist bcma-pci-bridge" > /etc/modprobe.d/bcma-pci-bridge.conf

And then, before restarting, installing the broadcom-wl-dkms from the community repository:

pamac install broadcom-wl-dkms

Very important is to ensure that during/at5 the end of the installation, no extra steps are given. If you’re unsure, provide the output here before restarting.

If no errors occurred, it should be safe to reboot.

It it’s still not working, post a

sudo inxi --admin --verbosity=7 --filter --no-host --width

…before uninstalling the drivers again.

If you need to have it working to do anything, just reverse the instructions for installing it:

Uninstall the broadcom-wl-dkms drivers:

pamac remove broadcom-wl-dkms

Unblacklist the bcma-pci-bridge driver:

sudo rm /etc/modprobe.d/bcma-pci-bridge.conf

…and rebooting. Then you should, again, be using the current driver which, as you say, is slow.

15

If you want to use wl on kernel 6.0 and don’t want to wait for the working version to migrate to stable branch, manual migration is possible.

The package is compatible and builds with 6.0 and older kernels.

Steps:

  1. install headers for kernels you have installed

For example

pamac install linux60-headers linux519-headers
  1. Download the specific version of the package

Choose a mirror from /etc/pacman.d/mirrorlist

Download these two files

unstable/community/x86_64/
    broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst
    broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst.sig
  1. Install the package
sudo pacman -U ./broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst

EDIT - as of Stable update 2022-11-02, this workaround is no longer needed.

16

thankyou you for the copius amounts of info! i’ll try and make it work.

FYI my Blue tooth stopped working .

17

If you have a blue tooth, I suggest a dentist.

Couldn't resist. Also, it's bluetooth, BTW.

I tried your fix and got the following
bash: /etc/modprobe.d/bcma-pci-bridge.conf: Permission denied

19

good one

20

That means the user you’re using don’t have permission to do it. Which I tried, and it worked. I suspect you forgot the sudo in front…

21

all i did was a copy paste…

will try again

22

davec@davec-notebookpc ~]$ sudo echo “blacklist bcma-pci-bridge” > /etc/modprobe.d/bcma-pci-bridge.conf
bash: /etc/modprobe.d/bcma-pci-bridge.conf: Permission denied

this is what happened

23

:confused: :thinking:

Try the following:

  1. Enter a root environment in the terminal:
su -

Use your root password to authenticate when requested.

  1. If successfully authenticated, run the command from within the root terminal:
echo “blacklist bcma-pci-bridge” > /etc/modprobe.d/bcma-pci-bridge.conf

The sudo part shouldn’t be necessary.

:bangbang::bangbang: Be extremely careful in the root terminal, as there is the very real danger of breaking you system completely :bangbang::bangbang:

:bangbang: Tip:

When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

For more information, please see:

24

i tried to build it like you said but I must be missing or not understanding some of the steps

25

If you provide output for the following, I can tailor steps 1 and 2 to your setup.

mhwd-kernel -li
head -20 /etc/pacman.d/mirrorlist

I was able to backlist the “bcma-pci-bridge” and then do the “pamac install broadcom-wl-dkms”. I’m back to having to select the kernel i want to boot with and all goes well and back to working properly including my acking Bluetooth :grinning: . When I reboot without first selecting a kernel I go back to no Wifi or Bluetooth but whats weird is the led on the function button(F12) is lite like the Wifi is working but the Icons in the tray show nothing.

Go figure

That might be because your grub doesn’t boot the last used kernel, which would be the working one, but the latest kernel, which is version 6. I’d need the output of

uname -r

…from both the working, as well as the non-working boots to confirm/deny that theory.

29

Your custom steps, to get broadcom-wl-dkms working on kernel 6.0:

  1. install headers for kernels you have installed
pamac install linux510-headers linux515-headers linux60-headers
  1. Download the newer version of the package broadcom-wl-dkms 
curl --remote-name "https://ftpmirror1.infania.net/mirror/manjaro/unstable/community/x86_64/broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst"

curl --remote-name "https://ftpmirror1.infania.net/mirror/manjaro/unstable/community/x86_64/broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst.sig"
  1. Install the package
sudo pacman -U ./broadcom-wl-dkms-6.30.223.271-35-x86_64.pkg.tar.zst

EDIT - the steps can be run on any of the three kernels, but steps 1 and 2 need working internet,

EDIT 2 - as of Stable update 2022-11-02, this workaround is no longer needed.

30 
This is when I had selected the Kernel to boot(F12)

davec@davec-notebookpc ~]$ uname -r
5.15.74-3-MANJARO

This is a reboot without selecting the kernel

[davec@davec-notebookpc ~]$ uname -r
6.0.2-2-MANJARO

You are right!!!
31

Howdy Mishmosh
Your custom code worked great, I was able to build a working driver that worked with the 6.02 kernel. I now have working high speed Wifi on 2.4 and 5g and BT to boot with 25+ft range. I works even after multiple boots without having to select a kernal.Not bad for a $10 board.

I really appreciate the help of crew on this problem. Mirdarthos, Mishmosh and j8a all gave good direction and I was able to learn some new things to put in to my tool box for later use. I ended up having two different fixes I could have gone with, being able to build a fix to use with the new kernel was what I ended up going with.

Than you all for your hard work
