Broadcom BCM43224 - Wifi not working

Technical Issues and Assistance Drivers
,
#1

WiFi doesn't work with Manjaro, despite having a WiFi switch. Is there a driver that I can use?

This page doesn't look helpful: https://www.dell.com/support/article/au/en/aubsd1/sln311232/how-to-download-drivers-that-are-unavailable-on-dell-support-website?lang=en

Additionally, a separate hardware issue is that my Ethernet cable bought for use in Australia doesn't work in a socket in Switzerland that has an internal CAT6 cable connected to it that is ISO-EN compliant. The cable is CAT6, verified to TIA/EIA-568-B.2-1 (other seemingly irrelevant details e.g. #R7J704 and the images below).

Please post the output of the following commands:

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

I transferred the output via mtp usb to my phone, which I'm posting from:

I ran sudo modprobe bcma and sudo modprobe e1000e. There was no output for either and WiFi doesn't work with the hardware switch on.

I also tried to reinstall hardware drivers, including the BCM43224 802.11a/b/g/n (Broadcom) network-broadcom-wi driver, but the changes failed because I don't have an internet connection: https://pastebin.com/P2rkTjd6.

I could connect to the internet via the live usb so I'll try to reinstall via chroot, later. While it's a separate but related issue, I'll also try to get and use an ISO-EN compliant CAT6 Ethernet cable.

Please see this post to install the broadcom-wl-dkms driver:

Also be sure to install kernel 5.0 with the appropriate kernel headers. If 5.0 does not work well then test 5.1.

Use Android phone tethering to get a connection.

Thanks!

I have installed additional kernels so that I now have all available kernels installed (LTS, 4.20-5.1rc and the now unsupported 4.18.16_rt9-1) and installed all the headers. After installing the dkms package, WiFi didn't work in 5.1 (I forgot to test 5.0). This is the output with installing the proprietary driver:

As you can see there was an error for kernel 5.1 so I'll reboot into 5.0. Due to the missing kernel headers for 4.19.31-rt18 and 5.0.7-rt5, I also reran:

I'll just ignore installing kernel headers for the real-time kernels for the time being.

Rebooting into 5.0.7-1 now. I still can't boot into it, I'm still getting the same init not found error as with Kernel panic - not syncing: No working init found. I can boot into 5.0.7-rt5, but WiFi doesn't work there.

James I've worked with you before and you are very difficult to troubleshoot anything with. You are a capable user, but you simply are too impatient and run ahead before you are instructed to do so.

Did I ask you to install every kernel under the sun including the real time kernels. Are you going to be available for an hour of two at least to work on this problem. You have made troubleshooting this issue overly complicated by installing all these kerrnels with errors thrown during the installs.

Are you willing to do only as I instruct and nothing else. If not, I cannot work with you. We have barely begun the install process and I'm already extremely frustrated because of your actions.

@jamesray please

check

@jamesray , you have some trouble since this


you should check carefully your log

Yes, ready to follow your instructions and nothing more.

Running now. I'll pause and await instruction.

First thing switch to kernel 4.19

I'm not going go dig to find out all the different drivers versions you installed. Go into Manjaro Settings Manager and uninstall every instance of the wl driver you have installed.

sudo pacman -R linux$(uname -r| grep -o -E '[0-9]+' | head -n 2 | sed 'N;s/\n//')-headers
sudo pacman -R dkms
sudo mhwd-kernel -r linux316 
sudo mhwd-kernel -r linux318 
sudo mhwd-kernel -r linux44 
sudo mhwd-kernel -r linux49 
sudo mhwd-kernel -r linux420 
sudo mhwd-kernel -r linux50
sudo mhwd-kernel -r linux51
sudo depmod -a
sudo mkinitcpio -P

If there are any errors on any commands please post the outputs.

Reboot.

#10

Check your wifi status after you have rebooted into kernel 4.19.

#11

Alright, done.

#12

Do you have any connectivity with the kernel module on 4.19.

Before we can get started I need to doublecheck that all necessary changes are ready before we begin the reinstall.

I will need quite a few outputs to determine if everything is correct:

rfkill list all

lsmod | sort

dkms status

sudo mhwd-kernel -li 

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

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

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

I will need a bit of time to review all the outputs.

#13

Only via USB tethering. No WiFi networks are available.

Shall I run sudo modprobe bcma?

#15

James please never edit command outputs. You must show the full input and outputs of all commands.

Try this:

sudo rmmod b43 b43legacy ssb brcm80211 brcmfmac brcmsmac bcma 

sudo modprobe -r wl

sudo modprobe b43

Please post the full input and outputs of all commands.

Is the broadcom adapter you are tying to get working a USB adapter?

#16

I didn't edit them. The confusion may be from that I copied and pasted all commands and then pressed enter, rather than running them one by one.

No change in wifi status, is this a usb or internal wifi card.

Please run:

sudo pacman -R linux414-headers
#20

No change in wifi status. This has an internal wifi card, not a dongle.

As above:

  Model: "Dell Wireless 1520 Half-size Mini PCIe Card"
    Driver Status: bcma is not active
    Driver Activation Cmd: "modprobe bcma"

Running

sudo pacman -R linux414-headers

Done, no error.
