After a recent upgrade network manager now fails to automatically connect to my wireless network. The connection fails with a "connection deactivated" notice. After that I can connect by manually selecting my network connection from the network manager's list of available networks. But I wonder why it has stopped working automatically? Has anyone else encountered this problem? Tim -- Tim Folger www.timfolger.net +1 505 217 3702
