Public bug reported:
After upgrading to 2.6.20-7-generic, NetworkManager/nm-applet does not
recognise any network interface. I have wired and a wireless interfaces,
and nm-applet reports "No network connection".
Nevertheless the wired interface successfully negotiated an DHCP IP
address, and attached.
I am unsure on where the problem actually is -- hal, udev, dbus, NM, or
the interface between them and NM.
I have NM running with debug set. ON 2.6.20.60-generic, this is what NM
reported:
