Neither wireless nor wired connections after updating core from 4.4.0-71 to 4.4.0-72

[karu]

Ubuntu 16.04.2 LTS
After updating the core to 4.4.0-72, suggested by Software Update Manager, Network Manager does not see Wi-Fi.
Initially when Ubuntu is loaded the sign of Network Manager does not appear in tray. Wireless button flashes orange instead of white and doesn't react on pressing. When I'm trying to open Network Manager through System Settings it flashes a notification that some connections are not suitable for this version. When closing the notification the only thing manager shows is proxy settings and the only thing it suggests for adding is VPN. Not any word about wireless or wired connections at all!
As for Apport it's still keeping silence. Drivers remained the same.
As I checked there are no any kind of block for the connections (neither soft nor hard). When I boot with core 4.4.0-71 everything works perfectly as it did until updating.

Please ask me and possibly guide me if solution needs more information, logs, etc.

After some days of working under the old core and installing updates that followed thereon everything's returned to normal work.

But I still do not know what it was!
