Finally some good news. Broadcom seems to have fixed the Freeze bug in their latest driver version 6.30.223.271. Unfortunately, there's no Ubuntu package yet, but there's a Debian package. You just have to purge and hide bcmwl-kernel-source for good in synaptic or via dpkg or apt and install broadcom-sta-dkms.
# sudo apt-get install broadcom-sta-dkms Works perfectly on Ubuntu 16.04 amd64 with Kernel 4.4.0-24-generic and broadcom-sta-dkms (6.30.223.271) The only nuisance is that with every Kernel Update you'll have to reinstall broadcom-sta-dkms for the new kernel. We will just have to wait until Ubuntu uses the Broadcom 6.30.223.271 driver in bcmwl-kernel- source ... So for now it's finally fixed!!! ** Changed in: bcmwl (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445458 Title: BCM4360 bcmwl-kernel-source System Freeze every few Seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1445458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
