Hi,

NetworkManager 1.8.1 was released in 2010 -- plus your version contains
countless downstream fixes (107) applied by RHEL/CentOS.

Upstream does not support such old versions, so you might not get help
here (but I don't want to preclude that and you're welcome).

I would however suggest getting help from your distribution :)


best,
Thomas
