Comment 59 for bug 1542733

That's an old report and some comment states it's fixed with the patches from https://bugzilla.gnome.org/show_bug.cgi?id=597839 which are in Ubuntu versions newer than 16.04.

Closing that report it's confusing as this point since it has comment from users having different issues.

If anyone can still reproduce on 18.04 or newer please report a new bug using 'ubuntu-bug network-manager'
