Network Manager service vs Network service
 

On Fedora 10 the Network Manager service handles networking by activating the networking device on request. After an upgrade attempt to Fedora 11 the Network Manager has been left in an undefined state without a working network access. As a quick solution I have turned the option to allow control by the Network Manger, and instead use the standard Network service by activating the ethernet device at startup.

Unfortunate side effects are:

- Firefox always starts in offline (didn't do that before, and doesn't remember my setting to go online after a reboot)

- Re-enabling the Network Manager takes over the device again, but reports no networking (obviously something has been messed up behind the scenes), and does not allow to activate the device by hand via the Network GUI interface

I am able to set up networking, but it gets annoying to fiddle with this after each new booting. All hints are appreciated!

This is exactly why one should not attempt to upgrade a running system. A fresh install creates a known environment. An upgrade creates unknown side effects with previously installed software.

My advise is to install FC 11 onto a new partition.

The amazing part of the whole thing is that the system hasn't been even upgraded to Fedora 11 - I have been asked by system since then if I want to upgrade to Fedora 11. I tend to believe that this has rather to do with some glitch in Fedora's default updater tool (the one that puts up those nice little dialog boxes once in a while quite unexpectedly), and not with a finished upgrade. In the past I have done release upgrades manually by using 'yum upgrade', and that has always worked for my purposes. Automated updates with 'smart tools' are always tempting, but you can never know for sure what happens behind the scenes. I just wonder why the NetworkManager does not regain control when set to do so. Right now I consider re-install the NetworkManager.
