I think this bug is fixed after 16.04.01. I no longer have this problem on a fresh install of Ubuntu MATE 16.06.1 64-bit, as well as on doing an upgrade from Ubuntu 14.04 64-bit to Ubuntu 16.06.1 64-bit.
However, my previous installations/upgrades of Ubuntu 16.04 64-bit still have this problem even with the packages up to date. My advice is to do a fresh install of a current 16.04.1 ISO or, in the case of an upgrade, if you still have a backup of your 14.04 installation, try to use it to upgrade as of today and discard previous attempts. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434986 Title: Not working network connection after boot To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1434986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
