I think there is bug in NetworkManager. I have also faced lot of problems with NetworkManager specially on wired LANs. So I always disable it and using only network services. For wireless NetworkManager makes it easy to reconnect so is usually worth the trouble. Update to latest version of NetworkManager of your distro and that might help. | |||
