This is actually about two bugs in one and related to bug 1804841 Lets disambiguate them.
One can be avoided by a config in network-manager as mentioned in comment #19 Lets handle this bug here as "that one" - at least in Bionic and later - fixed by being set by default. This was initially fixed in 1.12.4-1ubuntu1 >From changelog: - NetworkManager.conf: disable MAC randomization feature. There is no easy way for desktop users to disable this feature yet. And there are reports that it doesn't work well with some systems. And also became part of Bionic in 1.10.6-2ubuntu1 I'm marking this bug fixed since Bionic due to that. --- Everyone else still affected despite this workaround has another yet unclarified issue.
