There are many bugs in the network-manager package. The Debian BTS has a list of all network-manager issues.

That doesn't mean you should give up on Network Manager; if everyone does that, then it will never improve. –  crb Jul 20 '09 at 18:44

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.
