There is no wireless connectivity in ubuntu 16.04.1 here is more information I already tried this one, which suggested downloading the deb file and manually installing the broadcom-wireless driver package. No more wireless after quantal update: 'Module wl not found'

Running sudo dpkg -i bcmwl-kernel-source_6.30.223.141+bdcom-0ubuntu2_amd64.deb returns:

(Reading database ... 181254 files and directories currently installed.)
Preparing to unpack bcmwl-kernel-source_6.30.223.141+bdcom-0ubuntu2_amd64.deb ...

Therefore running sudo modprobe wl returns:

lspci -knn | grep Net -A2 returns:

One issue is that you are installing an older version of the package; let's remove it:

sudo dpkg -P bcmwl-kernel-source_6.30.223.141+bdcom-0ubuntu2_amd64.deb

Next, please see:

Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.

Please get a temporary internet connection and do:

sudo apt-get install --reinstall linux-headers-generic

Once the reinstallation of the headers is complete, next do:

sudo apt-get install bcmwl-kernel-source

Please post any errors or warnings.

  • I am not quite sure OP has a Broadcom. Too many people think that "Broadcom" means "wireless". – Pilot6 Aug 11 '16 at 14:07
  • LOLOL! Indeed. We will be interested to see his lspci. – chili555 Aug 11 '16 at 14:08
  • Thanks chilli555. Here is what reinstalling returns- Error! Bad return status for module build on kernel: 4.4.0-34-generic (x86_64) Consult /var/lib/dkms/bcmwl/6.30.223.30+bdcom/build/make.log for more information. Setting up linux-headers-generic (4.4.0.34.36) ... – DarthRhaego Aug 11 '16 at 14:57
  • @Pilot6, True true! But I have a broadcom. – DarthRhaego Aug 11 '16 at 15:09
  • Please run: cat /var/lib/dkms/bcmwl/6.30.223.30+bdcom/build/make.log and paste the result here and give us the link: http://paste.ubuntu.com – chili555 Aug 11 '16 at 15:25

    I'll take a shot without even seeing the log! Please see my edit above in a few moments. – chili555 Aug 11 '16 at 15:32
  • Hey! chilli555, I removed and installed it again, the wireless module wasn't found. I'll try reinstalling the generic headers and dkms modules again try again. – DarthRhaego Aug 12 '16 at 05:35
  • You're the greatest chili555!!! Thanks a lot! It worked. – DarthRhaego Aug 12 '16 at 05:41

If you don't know anything about fixing the problem yet and you dont know whats wrong read: Installing Broadcom Wireless Drivers . If the specific obstacle is WL not found continue. This procedure worked for a Broadcom PCI:ID 14e4:43b1. You will need an internet connection (through ethernet cable for instance).

The current general solution is to deactivate/uninstall the Broadcom wireless module and rebuild it - because something has gone wrong. There's a huge amount of info on how to do this, and you may have to reboot and other stuff, I wont go into that here, see the above link.

But (if you read the output when rebuilding) you may get the WL not found error like I did and it just wont work. This was very frustrating after 10 hours of syncopated reboot uninstall install, UEFI secureboot off, proprietary driver click on/off etc.

Long story short, Type the following to see if you have the headers for your Linux distribution:

ls -l /usr/src/linux-headers-$(uname -r)

This command ls combined with uname -r above will list your headers (for the exact version of Ubuntu you have) It wont do anything else. If you don't have the files nothing will be returned (and that's why the WL component wont build). If that's the case the following may fix your problem - Get the headers by typing:

sudo apt install linux-headers-$(uname -r)

now that you have all the pieces (hopefully) you can rebuild the module by typing:

sudo apt install bcmwl-kernel-source

OR (if you have not uninstalled it - reinstall it using):

sudo apt reinstall bcmwl-kernel-source

If it works you will see the wireless icon in a few seconds.
