Wi-Fi disconnects 24.04.1 LTS (BCM4313 802.11bgn Wi-Fi card)

Vito · September 2, 2024, 8:00pm

Hello, fellow Linux users!

I’m reaching out to the community for help in fixing a Wi-Fi issue on Lubuntu version 24.04.1.

I have a laptop with a BCM4313 802.11bgn Wi-Fi card. Previously, I used Windows 7 and Windows 8 on this same machine without any Wi-Fi issues. However, on Lubuntu, the Wi-Fi connection only stays active for about 5 minutes before disconnecting. After it disconnects, the Wi-Fi becomes inaccessible until I reboot the laptop.

Before posting here, I searched for solutions in the Ubuntu community and tried the following (none of them worked):

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
And changing wifi.powersave to 2.
Disabling IPv6

I also came across a possible solution but am unsure how to implement it. On AskUbuntu, the OP resolved a similar issue by changing the OS default driver to firmware-b43. Unfortunately, I can’t identify the name of my current driver to try this solution.

At the moment, I have reinstalled Lubuntu to ensure that nothing I tried earlier interferes with the solution.

Here is some additional information that might be relevant:

Hi Vito!

One option you can try is to install Broadcom’s proprietary STA (or “wl”) driver. If you’d like to try this particular driver, I think probably the easiest way to install it would be to go into “Software Sources” in the main menu (under “Preferences,”) then once the window appears, click on the tab that says “Additional Drivers.” Wait for the app to load the names of the devices that Ubuntu has proprietary drivers for in their repositories and see if your wireless adapter is listed. If so, click on (or tick) the circle that lists the STA driver and then click the button that says “Apply Changes” on the bottom right of the window. Once the app gets done installing the driver, reboot the system and see how it works. Hopefully, this will resolve your issue.

Regards…

Vito · September 3, 2024, 5:08pm

I tried the easiest way.

It was marked on “Do not use the devide”. I switch to the STA option, apply the changes and reboot the laptop. Didn’t fix the problem

.
Maybe another driver could fix it?

ardvark71 · September 3, 2024, 7:27pm

Hi Vito…

Possibly, Lord willing. From the first answer on this thread…

You can open a terminal and run the following command…

sudo apt-get purge bcmwl-kernel-source && sudo apt-get install firmware-b43-installer

Just as a heads up, I’m not sure the “firmware-b43-lpphy-installer” should be used for your chipset. From my limited understanding, I think this version is only for the BCM4312 chip, which yours isn’t. Perhaps someone else on the forum can advise.

Hopefully, this resolves the issue.

Regards…

Vito · September 3, 2024, 9:13pm

Once again, I tried your suggestion, my friend. I used the code and managed to download the firmware-b43-installer, but the sudo apt-get purge bcmwl-kernel-source resulted in:

Package ‘bcmwl-kernel-source’ is not installed, so not removed

After that, I went to “Additional Drivers” to try using that driver, but it only had the same two options as the image I sent. I switched to “Do not use the device” to see if it would work. I rebooted the laptop, and the Wi-Fi disappeared . I went back to the “STA” option, and the Wi-Fi presents the same problem as before.

Even though it didn’t solve the problem, I appreciate your contribution ardvark71.

ardvark71 · September 4, 2024, 1:47am

Hi Vito!

You’re very welcome and I’m sorry this is happening! If you would, with the STA driver disabled (meaning that the option “Do not use the device” in Software Sources/Additional drivers is ticked,) would you please post again the results of…

sudo lspci -knn | grep Net -A3

I would appreciate it! Something seems off here, what did the terminal say after it finished installing the firmware installer?

I am, by no means, an expert in installing Linux wireless drivers (or any other Linux drivers,) so if you have the time and inclination to keep plugging away at this, I’m happy to help you, Lord willing. We can learn together.

Regards…

Vito · September 4, 2024, 8:01pm

I ticked “Do not use the device” and use the sudo lspci -knn | grep Net -A3

Hi Vito

Well, at least Lubuntu still sees that you have the Broadcom adapter. That’s good, praise and thanks to God! From the results you submitted in your last post, it appears the “firmware-b43-installer” was successfully installed. At this point, please make sure the option “Do not use the device” in Software Sources/Additional drivers is ticked and then open a terminal and enter the following command…

sudo apt install linux-firmware

This is based on the information I see from this page…

https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers

From there, I learned that your device requires the “brcmsmac” driver. Please see the section that says “Drivers for the 4313.”

After installing the package mentioned above, please copy and paste the results in your next post and then reboot. Does this help at all? If not, try these commands and see what happens…

sudo rfkill unblock all

sudo ip link set dev wlan0 up

If it’s still not working, please tell me what happened and post the results of the following command…

sudo lsmod | grep brc

Thanks!

Regards…

Vito · September 5, 2024, 7:19pm

Hello ardvark71 =).
About your sugestions:

The result:

linux-firmware is already the newest version (20240318.git3b128b60-0ubuntu2.2).

Then, i used the sudo rfkill unblock all. I guess the result was turning on my bluetooth.

Using the sudo ip link set dev wlan0 up give me:

Cannot find device "wlan0"

Finally, i used the sudo lsmod | grep brc:

brcmsmac              802816  0
brcmutil               24576  1 brcmsmac
cordic                 12288  2 b43,brcmsmac
mac80211             1720320  2 b43,brcmsmac
cfg80211             1323008  3 b43,mac80211,brcmsmac
bcma                   86016  2 b43,brcmsmac

Well, it didn’t work, but i read the link you send. The next step would be the blacklist, but I don’t know which drivers I can block without breaking the right one.

ardvark71 · September 6, 2024, 2:56am

Hi Vito!

I’m guessing your adapter is using another name, not “wlan0.” Could you post the results of this command…

sudo nmcli --get-values GENERAL.DEVICE,GENERAL.TYPE device show

As a suggestion, you could try blacklisting “b43” and “b43legacy” first, Lord willing. Do you know how to do this? If not, please post back and let me know before attempting to do this. Also, so I have a better understanding of what you’re dealing with, could you post a screenshot of what you see when you click on the network icon on the toolbar? What is listed in that menu? You mentioned that you don’t have wireless at the moment, I’d like to be able to see what you’re seeing, as much as possible, LW.

Regards…

Vito · September 6, 2024, 4:43pm

You are corect. The name is wlp5s0b1. Using the right name, i used the sudo ip link set dev wlp5s0b1 up command. The terminal did’t show anything, but think it accept the command. The Wi-Fi keeps disconnecting =(.

Furthermore, i blacklisted the “b43” and “b43legacy”. Now, the sudo lsmod | grep brc looks like this:

Also didn’t solve the issue. I tried blacklisting “bcma”, but this vanishes the Wi-FI, so i undid this action.

My tollbar looks like this:

ardvark71 · September 7, 2024, 9:42am

Hi Vito!

Thank you for posting the screenshots, I appreciate it! On the driver front, you can try solution mentioned at the last post here…

https://bbs.archlinux.org/viewtopic.php?id=187788

which, essentially, is to install the STA or “wl” driver and blacklist the entries the OP listed. Here is another thread I found might be of help, I’m not sure…

https://askubuntu.com/questions/110584/bcm4313-wireless-card-keeps-disconnecting

However, before you do this, I’m wondering if this isn’t a driver issue but something else that’s causing the constant drops or disconnects? Even though the OP is using a different Broadcom adapter, I found the thread here, which leads me to think this is possible…

https://unix.stackexchange.com/questions/545336/wireless-card-keeps-connecting-then-disconnecting/545440

If you would, please open a terminal and post the results of…

sudo dmesg

It might be kind of long but that’s OK.

Regards…

Vito · September 7, 2024, 10:38pm

Hello!
In the meantime, I tried a few things on my own. Somehow, the wifi went away forever . Anyway, I reinstalled Lubuntu and used parts of the suggestions from this thread again:

sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo apt install linux-firmware
sudo rfkill unblock all
sudo ip link set dev wlp5s0b1 up

And the: sudo lsmod | grep brc

brcmsmac              802816  0
brcmutil               24576  1 brcmsmac
cordic                 12288  2 b43,brcmsmac
mac80211             1720320  2 b43,brcmsmac
cfg80211             1323008  3 b43,mac80211,brcmsmac
bcma                   86016  2 b43,brcmsmac

Like last time, it didn’t solve the issue.

Perhaps. I mean, we tried most possible solutions and nothing worked.

I used the command sudo dmesg and read the thing. Didn’t understand 99% of it, but there is some information about bcma errors. I’m sure you can make use of this information. Also, I haven’t tried the other suggestions you sent me. I think it would be better to analyze the sudo dmesg data first. Sending from the first mention of bcma:

Hi Vito!

Thank you for posting the dmesg report, I appreciate it! Unfortunately, the only two entries that stand out to me are the following…

[   18.658657] b43: probe of bcma0:1 failed with error -524

[  509.029193] brcmsmac bcma0:1: ops->tx called while down

After a brief search online, I wasn’t really able to find anything concerning these two error messages. However, I did find a couple old threads that might offer a solution, although they’re along the lines of what I’ve already suggested and what you’ve already tried. Please have a look at post #15 here and post #9 here. Also, although it’s a long shot, from what I saw on the thread linked to below, you can also try reseating your wireless adapter and see if that helps…

https://linux.debian.user.narkive.com/bhKYtxIn/broadcom-bcm43225-wireless-shows-not-connected-then-hardware-disabled

At this point, apart from trying my other suggestions or purchasing a Linux compatible USB wireless adapter, like the one here, I’m not sure what else to suggest.

EDIT: Lord willing, there is one more possibility I just thought of. You can try seeing if Chili555 can help you with this. This gentleman really knows his stuff when it comes to wireless networking!! I’m not sure if his email address is still current and/or if he’ll write back but, if you want, you can try contacting him using his contact information here. Perhaps he might be willing to post here, as well, LW.

Regards…
