Ubuntu – How to fix Broadcom driver Wifi with 4.15.0-xx kernel on Ubuntu 16.04

16.04broadcomdriversnetworkingwireless

I reinstalled a driver on Windows for Broadcom Network Adapter and after that my WiFi stopped working on Ubuntu(16.04) completely.

I tried to reinstall drivers, using this commands:

1. sudo apt-get purge bcmwl-kernel-source
2. sudo apt-get install bcmwl-kernel-source

But it didn't help

Output of the second command(install bcmwl-kernel-source):

bcmwl-kernel-source is already the newest version (6.30.223.271+bdcom-0ubuntu1~1.2).

This command lspci -nn -d 14e4 outputs:

Could you tell me how to fix my problem?

  • Canonical updated HWE stack for Ubuntu 16.04 to the 4.15 kernel. But they forgot to update the Broadcom wireless driver, so it can be built. It is a critical and a very stupid bug, that will cause trouble for many people using the LTS.

    Now the issue is being fixed and a compatible driver version has been built

    This issue can be solved by installing a compatible version of bcmwl-kernel-source that should build on the 4.15 kernels.

    Download http://archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb

    and install it using dkpg.

    This can be done by

    wget http://archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb
    sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb
    

    Windows is not related at all.

    The problem is that you have a kernel that is not compatible with the driver.

    Important: If you don't have any other network connection but the Broadcom Wi-Fi, you can boot with a previous kernel using grub menu and install the driver. It should build for all kernels.
