I updated my kernel to fix a problem with a graphics driver (namely AMDGPU-PRO from AMD) and it works like a dream now

However, if you fix one problem - another problem will arise. The bcmwl-kernel-source (WiFi driver for the AC1900 wireless card) doesn't seem to work at all?

Usually on the kernel on Linux Mint 18.2, (I have no clue how to solve this problem) I have to re-install the WiFi drivers on reboot. using

sudo apt install--reinstall bcmwl-kernel-source

And it works as if nothing is wrong, tested it 4 hours straight and got a solid 8 megabytes/s peak.

Other information that I wouldn't mind speaking of: The PCIe ID is 14e4:43e0 / BCM4360

These were the error logs when trying to do re-install whycan'tnewlyregisteredpeopleputpictureshere >:(

And I'm using a computer that I've built, and the specs are:

  • GA-Z270X UD5 motherboard

  • i7 7700k (kabylake) CPU

  • RX 560 graphics card
  • Crucial ballistix elite 2666MHz (2 x 8gb kit) memory
  • TP-link Archer T9E AC1900 (aka the problematic card) wifi card

I'm also very new to Linux. so please go easy on me :p


I just had this problem as well after upgrading from 4.10 to 4.12.3 to fix an audio issue.

What I did to fix the problem was revert back to 4.10, and then just upgrade to 4.11.12 instead.

sudo apt-get remove linux-headers-4.12.3*

sudo apt-get remove linux-image-4.12.3*

It fixed my audio issue and played nice with the wifi driver.

Seems like either 4.12 or bcmwl-kernel-source don't support one another yet.

Hopefully this helps.


Latest bcmwl-kernel-source now supports kernel 4.12 and 4.13.

To download and install latest: wget https://launchpad.net/ubuntu/+archive/primary/+files/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb

Then rebuild your kernels with new module: ls /var/lib/initramfs-tools | sudo xargs -n1 /usr/lib/dkms/dkms_autoinstaller start
