I had this problem WITH the package bcmwl-kernel-source 6.30.223.271+bdcom-0ubuntu1~1.2. But found the solution here: https://elementaryos.stackexchange.com/questions/15842/bcm43142-and-linux-kernel-4-15-0-24-generic
"I had to download the package for 18.04LTS (https://packages.ubuntu.com/bionic/bcmwl-kernel-source) and install it using:
sudo apt-get remove --purge bcmwl-kernel-source sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb"
That worked perfectly for me. Fortunately, I found this solution before rebooting so I've never lost conection in the process. My ubuntu kernel is 16.04.13. My wifi card is BCM4313 802.11bgn.
