lsb_release -rd
Description: Ubuntu 16.04.5 LTS
Release: 16.04
linux-image-4.4.0-135-generic
Ubuntu updates operating system which is nice, but after updates are
installed I select shut down from desktop and next day/moment press the
power on all the wifi/connections/network devices are missing. If I
shutdown and power on second/third the network connections don't get up.
but when I reboot (using the same Ubuntu panel on desktop) all network
connections are suddenly there up and working. Also after Ubuntu updates
the operating system and instead of reboot steps do the same shut down
from desktop - the next poweron stops on just black screen without
ubuntu logo (and never see loading the login desktop manager with Ubuntu
logo).
e.x. this is in /var/log/syslog when wifi connections don't get up
normally after update and I do poweroff/poweron
