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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724863 Title: bcmwl 6.30.223.271+bdcom-0ubuntu1~1.1 ADT test failure with linux-hwe- edge 4.13.0-16.19~16.04.3 [error: ‘struct net_device’ has no member named ‘last_rx’] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1724863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
