Network Management

Network Not Online
If you did NOT select Configure Network during CD/DVD installation, then the network will not be online by default. To fix this, make either of the following changes:
Option 1: EDIT: /etc/sysconfig/network-scripts/ifcfg-pXpY and change ONBOOT=no to ONBOOT=yes.
Option 2: In Gnome, [Right-Click] on the Networking icon in the top left of the toolbar.
Select Edit Connections....
Select System pXpY and click Edit...
Check Connect automatically and click Apply.
Enter 'root' password when prompted.
Note: Due to changes in Fedora 15, network device names are no longer named as eth devices. They will use pXpY where the X and Y are numbers which correspond to your specific system's pci slot number and port number. Hence network device names may be different among different hardware.

I have bitten the bullet and done a complete clean re-install for Fedora 14.
My reasons (not in order):
1. Network Manager - I was just not confident I could get all the issues with from basic eth0 (now pXpY) wireless, VPN solved and stable
2. Rythmbox was crashing
3. I use the Gnome 2 Locations function everyday
4. Mumble had microphone issues
5. the current way of jumping between and seeing Workspaces in Gnome 3 is very awkward - bring back Panel!!
6. I couldn't get file management to display in List mode - Icons take up too much screen space
7. No direct screen label to Shutdown is just another awkward inconvience.
Not a complete but not a big list.
I love the Gnome 3 interface but is it just too dumbed down?
I noticed really worthwhile performance gains.
It is such a pity that apart from the big issues with NM there are such irritations as no Shutdown on the User Panel.
I will grab a spare desktop and do a clean install but for my main laptop I think I will wait until Gnome 2 and NM is working properly.
Still a Fedora fan
