After auto-update from kernel 4.4.0-112-generic to 22.214.171.124-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.
