Ubuntu 14.04: After upgrade to kernel 4.4.0-116-generic Broadcom wlan does not function

After auto-update from kernel 4.4.0-112-generic to 4.4.0.116-generic, the Broadcom wlan adapter is no longer available. As I did not yet have time for further research, I removed the 4.4.0-116 kernel package and switched back to 4.4.0-112 to keep the laptop functional.
With kernel 4.4.0-112, it appears that the wlan-adapter uses the module wl.
I can't find any info on this issue in the 4.4.0-116 package's release notes.
Do I need to update the wl-module manually? Do I need another module?
Any help appreciated! And happy to provide more info if anyone point me to the right places to find it.

I had the same problem with my linux mint laptop today after upgrading from 4.4.0-112. I was unable to find any other solution so i just rolled back to my previous kernel.

In the 4.4.0-116 kernel, trysudo apt-get install --reinstall bcmwl-kernel-sourceThere is an issue with gcc and compiling right now bugs.launchpad.net/ubuntu/+source/xorg/+bug/1750937

@Jeremy31 I tried that, but it didnt work. It just disabled my wifi even when i boot with the 4.4.0-112 kernel. In case you have the same problem I fixed it by just switching a driver my driver with an other + reboot and then switch back to my original driver + reboot from the driver manager. I hope they fix it or else I will stay with the 4.4.0-112 kernel forever.

@theVoid you may also need the gcc-5 update otherwise the vermagic for the wl module isn't correct for the 4.4.0-116 kernel
