rebooting with an older kernel worked around the issue:

Hi.

I'm redirected here from bug #1770029

When upgrading kernel to 4.15.0-24-generic I also had problem with my broadcom network card : lost wifi

So I try to reinstall broadcom-sta-dkms :

:~$ sudo apt-get install broadcom-sta-dkms

The solution seems to be in the -proposed repo: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/1777444

So, I've tried to install the package in proposed and WiFi is working OK with kernel 4.15.

The package in proposed fixed the issue for me too.

Hi, how to fix this practically without compiling any code? Today i lost wlan and error message let me into this bug. Currently my laptop is a brick without wlan...

@Sami: the compilation is done automatically by the installer. You can either plug in Ethernet or reboot and chose Advanced Ubuntu boot option, scroll down to the previous ver. of the Kernel (4.13) and boot with it normally to get the WiFi connection back. Then "See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed" - just a couple of steps that don't affect your overall system if you "Create the file /etc/apt/preferences.d/proposed-updates with this content:...". Then sudo apt-get update and sudo apt-get install broadcom-sta-dkms/xenial-proposed. This should successfully compile for both 4.13 and 4.15 kernels. Then reboot normally and forget about this incident till the kernel testing flow breaks again next year or whenever.

Thank you @Stan! got it fixed!

Thank you a lot: easily fixed with "apt-get update/upgrade" today. Good work !

Is there a fix for the bcmwl package? I see that the broadcom-sta seems to have had a fix but I can't see mention of bcmwl? Or am I missing something?

Same here (broadcom-sta vs bcmwl).

Can a kind soul explains if one can be used instead of the other and why/how they differ ?

  // , I have the same problem.

If you're looking for a fix, someone made a post on the Ubuntu stackexchange:

https://askubuntu.com/questions/1052403/how-can-i-fix-broadcom-driver-wifi-with-4-15-0-24-kernel-on-ubuntu-16-04

How do we end up with a patch that deploys a version of our wireless driver that's incompatible with our kernel?

Should we start being more careful with kernel upgrades to LTS?

  // , Looks like there's an official fix that doesn't require drivers from Bionic here:

WORKAROUND: https://askubuntu.com/a/1052418/308869

I installed Ubuntu 16.04 on a MacBook Pro

I ran into this bug with today's update to kernel 4.15.0-29. I had no problem previously using the 4.15.0-24 kernel. The bug reporter automatically directed me to this bug report. I see similar issues, where my wifi adapter seems to have disappeared. I have not yet tried the workaround.

After browsing through some of the previous links, the proposed fix for the bcmwl version successfully solved the problem.

Hi Andrew,

4.15.0-29-generic upgrade did the same thing to my wifi adapter. My
connection settings still exist but no wifi capability at all.

Jeff

Here is what worked for me to restore WiFi functionality...

1. Run Software & Udpates from the launcher. In the Developer Options tab, check the box for Pre-released updates. This will require your admin password and will update the cache.

2. Run Software Updater from the launcher. It will present you with lots of options of stuff to update. Because I did not want to beta test the whole proposed release at this moment, but just fix my WiFi, I unchecked all of the updates except the Broadcom wireless driver. Then I installed this update, which did not require a reboot.

3. I tested the WiFi by unplugging the internet cable and connecting to wireless, which worked. A reboot was not requested so I didn't reboot.

4. Run Software & Udpates from the launcher. In the Developer Options tab, uncheck the box for Pre-released updates. This will require your admin password, again. It will update the cache. I did this because I don't want to install any further updates from the Proposed (pre-release) repository, just the one I needed to make WiFi work again.

My computer is a very old Dell Inspiron with Ubuntu 16.04. The wireless was working until I updated the OS this morning and the update failed due to a Broadcom driver problem, as described in this post and also here: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1777646. The above procedure corrected the problem without introducing any new problems. Thanks to everyone who contributed the fix! Much appreciated.

after latest update i lost wifi connection this mens im without INTERNET, how can this be possible and when can we have an update to fix it.

ok i did Run Software & Udpates from the launcher. In the Developer Options tab.

now it works,

tks for very important tip.

at this time ubuntu software store is limited so maybe they are doing something but now cant see my programs on the store

Hello,

I don't have even any network connection with the latest kernel
(4.*15*.0-24-generic)
. So what I am doing >> logging in the older kernel (4.*13*.0-45-generic)
and booting the Ubuntu 16.04 then only it is working.
I have tried several time the "Software and updates" from the menu but the
same situation.

Do someone have any software that I can download from the older kernel and
then login with the new kernel to install it. Because the on-line method
won't work from the new kernel system as because there is not Internet
connectivity (meaning neither wired LAN or WIFI )..

For reference here is the device details of *my *HP laptop n109tu red model

Same problem over here in an old DELL inspiron.
Thanks to Melissa's post (#25) it was solved.

How much will take to mark package bcmwl-kernel-source/now 6.30.223.271+bdcom-0ubuntu1~1.3 as tested if it is fixing bug from March, please?

I believe, this bug will not be used to push into upgrade to 18.04. Or?

@Marc Peña (pachulo)
Thank you very much! The fix is really in: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/1777444?comments=all

WORKAROUND: https://askubuntu.com/a/1052418/308869

on Ubuntu 16.04 LTS. Installed tightVNCViewer, now get this problem. Using usb wireless as old Dell broadband driver does not work. Dell M6300 laptop.

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install broadcom-sta-dkms

works for me as it was described in https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/1777444?comments=all

In which versions of the packages the fix is released? Which release of Ubuntu?

It works starting with 4.15.0-33-generic, at
least it did for me.
