No longer think this is a network-manager issue. On a fresh install I changed over to kernel 4.8.0-41 but did not perform any other updates and had the same issue. If I boot with the default 4.4.0-53 kernel I do not have this issue.

Confirmed issue with xenial-updates and xenial-security versions. Going to try to force a downgrade to original xenial to see if it still happens.

But once I attempted to connect / provide creds / etc it would bomb. Initially I thought it was dhclient but I don't think it is. Whatever else you need I can paste.
