Hi all,

Finally I managed to install wireless and now it is working. However,
my wired connection no longer appears in the network manager. In network manager menu it says "Wired Network device is unmanaged".
I have fc9 system.

In Network Configuration menu
in Devices tab it says inactive for eth0.

settings of eth0:
"controlled by network manager" is checked
"activate device when computer starts" is checked

automatically obtain IP address setting with dhcp is checked

any ideas?

thank you,
Ercan

Hello, I had the same problem: at my office I have both a wired and a wireless connection, but in fact only the wireless connection was in use. Running ifconfig indicated that I indeed received an IP for my wired connection via dhcp (and hence seem to have a connection), but the network manager applet stated that the wired device is unmanaged, and so did nm-tool (state wired: unmanaged) and investigatig networkd traffic it seems that only the wireless connection was functioning. Searching the web there was a phrase that network manager is only handling entries not in /etc/network/interfaces. Inspecting this file I found:

auto lo
iface lo inet loopback

iface eth0 inet dhcp
auto eth0

And indeed when I left out the last two lines, the network manager
is now handling the wired eth0 connection. Hopefully this works for you too.

Very right indeed Philbers !
My "/etc/network/interfaces" looked like this:

auto lo eth0
iface lo inet loopback
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1

After some tweaking my wired connection stopped working also. I couldn't find out howcome till I read your posting. Indeed after deleting the last four lines my wired connection (with static ip) was "managed" again by NetworkManager". Thank you for your help !
