Just Another Macbook WiFi Problem

[EmersonEXE]

Hey all,

I've been recently having some issues with MacOS on my device (Macbook Pro 15" Late 2014) so I decided to install Manjaro this afternoon and try to start hacking away at it.

I've followed several posts on the Macbook WiFi issues but fear I may have gotten things a bit tangled up. I'm sure that with some guidance I can get it working. This is the guide I was following: MacBook WiFi - BCM4360.

Everything worked up until the point I entered
sudo modprobe wl
where I get a prompt telling me the wl module can't be found.

Here is my output for sudo modprobe wl:

And the output for uname -r:

Before following the steps in the post above, my driver was being recognized as bcma-pci-bridge. Any help or guidance would be greatly appreciated.

This guide I wrote has full instructions:

Broadcom wifi driver fails to install properly

If your Broadcom wireless adapter driver is detected as "bcma-pci-bridge" or "b43-pci-bridge", your driver has likely been installed incorrectly. Examples: Kernel driver in use: bcma-pci-bridge Kernel modules: bcma Kernel driver in use: b43-pci-bridge Kernel modules: ssb If your WiFi connection is not working correctly you will need an alternate means to connect to the internet. You can use a wired LAN connection if your computer has a wired NIC (and a connection is available). The other…

Hey tbg! I was hoping you would be around as you seem to be the expert on all things macbook wifi.

What you've linked is actually the instructions I followed in the post I linked. Any ideas on how to better assess my situation?

[tbg]

Please post:

sudo mhwd-kernel -li 

dkms status

pacman -Q dkms

grep -r "blacklist\|install\|options"  /etc/modprobe.d/

pacman -Qsq linux | grep linux | grep -v -E '(arch|util|sys|api|firmware)' | grep -v nvidia

Thanks for being willing to help out!

Could you also please post:

sudo systemctl status broadcom

lsmod

[EmersonEXE]

Sure thing. Doesn't look like any broadcom service is running:

Unit broadcom.service could not be found.

[tbg]

Please post:

lsmod

So, from the first glace you do not have the dkms wl drivers installed and you have the kernel modules blacklisted . That means you in all likelihood have no drivers loaded. After you post lsmod I will know for sure.

Please explain what you've done to get to this point.

@tbg

Please explain what you’ve done to get to this point.

I followed the post above with the exception that I was unable to uninstall the bcma-pci-bridge drivers with sudo pacman -Rns bcma-pci-bridge. When I ran the sudo modprobe wl command I was getting an error that no wl module existed. I then tried to install a linux419-broadcom-wl and then uninstalled both it and the dkms-wl as neither were being recognized.

[tbg]

Run the these commands separately with a few seconds between entering each command in the terminal:

Do not cut and paste all the commands together at once. Enter each command individually.

sudo nmcli networking off

sudo systemctl stop NetworkManager

sudo modprobe brcmfmac

sudo systemctl start NetworkManager

sudo nmcli networking on

Please post the input and output of each command run.

[EmersonEXE]

sudo nmcli networking off

No output. Hardwired connection shut down.

sudo systemctl stop NetworkManager

No output.

sudo modprobe brcmfmac

Again, no output.

sudo systemctl start NetworkManager

No output.

sudo nmcli networking on

No output. A notification that my hard-wire connection couldn't be configured. I unplugged and plugged it back in and internet connection was resumed.

[tbg]

Do not restart unless I ask you to.

Please post again:

hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | grep -v "Config Status" 

[EmersonEXE]

Model: "Broadcom BCM4360 802.11ac Wireless Network Adapter"
    Driver Status: bcma is not active
    Driver Activation Cmd: "modprobe bcma"

  Driver: "igb"
  Device File: ens2
  Link detected: yes
    Driver Status: igb is active
    Driver Activation Cmd: "modprobe igb"

And I didn't restart the computer just replugged my ethernet connection. Otherwise I wouldn't have been able to post the results here.

Well from the looks of things this is a kernel or a firmware problem.

Do one one thing again. We will rerun those commands with an extra addition.

sudo nmcli networking off

sudo systemctl stop NetworkManager

sudo modprobe brcmfmac

sudo modprobe bcma

sudo systemctl start NetworkManager

sudo nmcli networking on

Please post the input and output of each command run. Do not add commentary of non outputs, simply paste the unabridged complete output and post it.

You are likely aware of this already, but I do believe bcma is on the modprobe blacklist.

[tbg]

Yes they are both on the blacklist , but that is a blacklist for when using the wl driver.
