Hi Dan, I tried this and didn't fix the problem. Did a 'setenforce 0',
then restarted the network, restarted NM and nm-applet, but it still
wouldn't connect. When the 'Wired Network' radio button is clicked on
nm-applet I get the following in the console:

 ** Message: Found connection 'Auto Ethernet' to activate at
/org/freedesktop/NetworkManagerSettings/0.

** (nm-applet:3839): WARNING **: <WARN>  activate_device_cb(): Device
Activation failed: Method "ActivateDevice" with signature "osoo" on
interface "org.freedesktop.NetworkManager" doesn't exist

Since this fedora is still version 8, I will probably upgrade to 12
and be done with it. It's just so weird that something like this would
happen :)

Cheers,
Daniel
