Network Manager, device not managed

I'm using a wired network.

After upgrading to Intrepid from Hardy, I noticed that the Network Manager had a little red x mark on it indicating that it was not detecting a network, and the "Wired" tab didn't list any connections. However the network was working normally, so I ignored it temporarily concentrating on continuing the upgrade to Jaunty and hoping that it will be solved then.

After upgrading to Jaunty the issue persisted; similar to what's described at http://ubuntuforums.org/showthread.php?t=1109585

Like what is described in the above thread, changing "false" in
[ifupdown]
managed=false

in /etc/NetworkManager/nm-system-settings.conf to "true" solved it and the connection is detected in NM.

However output of lspci | grep Ethernet is:

00:0c.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 86)

and output of sudo lshw -C network is:

when in fact my NIC is D-Link DFE-530TX PCI Fast Ethernet Adapter and was being detected as such in Hardy; i.e. before the upgrade to Intrepid.

I have the same exact problem, but in my case I have two network cards, eth0 and eth1 and I am connecting via eth0 that was configured with static IP address. Intially the eth0 shows as "device not managed" but the network connects and eth1 as disconnected. When I followed the workaround and I changed the
[ifupdown]
managed=false
to
[ifupdown]
managed=true
I completely lost my network connection.I have to change the /etc/network/interfaces from static IP address to dynamic IP address to bring my connection back. Then also I was able to change the managed to true to bring back the NetworkManager icon in the status area.

Hi Ahmad and bastafidli. Is this bug still present in Ubuntu 12.04?
