A customised new wired network connection is not very useful, because I have to choose the entry after every login.
Thanks for your help!
One way to do this:
1) System -> Administration -> Network
2) Double click on the 'eth0' item in that list
3) Customize the settings, add static IP, etc. Make sure the "Controlled by NetworkManager" box is *checked*.
4) Hit OK
5) Quit Network Configuration, and when it asks if you want to save, say "Yes"
You should now have a static IP address. If you don't, please attach /etc/sysconfig/network-scripts/ifcfg-eth0 and the output of /var/log/messages. That'll help figure out what went wrong.
