NetworkManager

Fedora 9 comes with the new NetworkManager on by default. This works fine for laptops, but for a wired desktop you may not want to use it. Here is how to disable it and set up the old Network service.
Run these commands:
sudo /etc/init.d/NetworkManager stop
(This disables NetworkManager)
sudo /sbin/chkconfig --level 35 NetworkManager off
(This stops it from starting on boot)
sudo /etc/init.d/network start
(This starts Network service)
sudo /sbin/chkconfig --level 35 network on
(This sets it to start on boot)
