Have you filed a bug report on this.
I read your link and to be quite fair to the devs reporting problems on another forum is not the way to go,
If these people had used this forum and reported bugs here then network-manager would of been fixed.
Please use the report bugs button if something fails.
I personally don't use a laptop and never have a problem.
