Also encountered very similar problem. I'm using Acer Aspire V7 laptop with Ubuntu 16.04 LTS. An update popped up, but I wasn't quite aware of what the update was about.
Restarted my computer, and then both wifi and ethernet connections stopped working. The situation matches with the bug description. "Enable Networking" checked, but no "Enable Wi-Fi". Both wireless and ethernet cards were detected, but no kernel modules seemed to be in use. Also, screen brightness could not be changed. The Logitech wireless mouse and the laptop touch screen stopped working. Same as what's mentioned, no such problems if after reverting to 4.4.0-75-generic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1687623 Title: linux-4.4.0-77.98 was a phased update in -updates only and may become partially installed (was: 4.4.0-77-generic breaks internet on 16.04.2) Status in linux package in Ubuntu: In Progress Status in update-manager package in Ubuntu: Confirmed Status in linux source package in Xenial: In Progress Status in update-manager source package in Xenial: Confirmed Bug description: Hi as per title today I updated to 4.4.0-77-generic on my Lubuntu 16.04.02 and wifi is not working anymore. When I click on the network manager I see "enable networking" (which is toggled) but no more the option about wifi. I reported this on ubuntuforum: https://ubuntuforums.org/showthread.php?t=2360216 Where a user suggested to revert to an older kernel and see if this fixes the problem. I managed to revert to 4.4.0-75-generic via grub and everything works perfectly. Another user reported a similar issue caused by the same upgrade on the same system: https://ubuntuforums.org/showthread.php?t=2360215 Can someone else confirm this bug?
