I followed https://wiki.ubuntu.com/Kernel/MainlineBuilds to install kernel 3.4 and 3.5 from debs.

Unfortunately after booting I can't connect to the internet cause I have problems with my network device BCM43228. The proprietary driver cannot be activated.

Jockey logs have:

and trying to do:

sudo apt-get install --reinstall bcmwl-kernel-source

results in:

Is there any support for this driver in linux >= 3.4?

  • For 16.04 all you need to do is make sure restricted drivers are checked in your software and updates sources and issue the command sudo apt-get install bcmwl-kernel-source

If you read the wiki, might I draw your attention to this bit:

By definition the mainline kernel builds are made from virgin unaltered mainline kernel sources and therefore do not, and should not, include any Ubuntu patches or drivers. There are also no binary drivers for these kernels.

Rather than the mainline builds, you will usually have better luck with the kernels for the next alpha/beta version (in this case, 12.10 Quantal Alpha 2), which should have binary drivers available:

  1. Get the 12.10 bcmwl-kernel-source package from the below link and try installing it with dpkg:

  2. If that doesn't work on your mainline build, install the 12.10 3.5 kernel images/headers, and then try again:


Note: Since you look like someone who should be fairly handy with this :), may I recommend you consider replacing the awful binary-only Broadcom card with one of the excellent Intel 6205 or 6300 half-mini-PCIe cards, which have fully open-source driver support in the vanilla kernel?

  • izx, thanks for the excellent reply. I had no idea I could install quantal kernels in precise. I will try the quantal kernels. Jul 12, 2012 at 10:45
  • Also, I bought an Asus P8Z77-I motherboard which comes with the broadcom card. I can't replace it... Jul 12, 2012 at 10:46
  • @PauloJ.Matos: It's even easier in that case! I did the same on my Asrock Z68 mITX a while back. Please see this image; carefully remove the two cable connectors by hand/fingernail, remove the one screw, and the card pops out. Replace with one of these, put the screw back and pop the cable connectors on. :D

  • izx, interesting. Didn't notice the wifi cards was so easy to remove when I assembled the PC. Are these cards sold by retail stores or you can only find them on ebay (and related) from old parts? Jul 12, 2012 at 15:57
  • @PauloJ.Matos: I doubt you'll find them in retail brick-and-mortar stores, but they're available easily enough online, e.g. Amazon UK. Note that these are never packaged as retail, but sold as OEM, so even a new one will likely come in just a plastic shell/antistatic bag.

Had the same problem with the kernel package I downloaded from xorg-edgers. I then downloaded the quantal version of bcmwl-kernel-source from here, installed it and my wireless card worked immediately.
