/var/log/syslog seems to contain debug information of network-manager, although I was not successful: With this command: sudo /usr/lib/NetworkManager/debug-helper.py --nm debug

I'm sure, I reinstalled Ubuntu many times, the issue still persist. Breaking of Wifi after computer wake up starts to appear, on average, after a week of computer usage. On my laptop, this Wifi problem existed in the previous Ubuntu versions as well. What works: It seems a simple Wifi turn off and turn on is sufficient, for the bug to go away. But I'm getting tired of this after years of doing it.
