Comment 8 for bug 188349

The same problem here.

When Hardy was installed "Enable roaming mode" was selected. However I have somehow managed to save static address in Network settings manager (when comp starts if I go and look in the setting all the values are there), but when the computer starts the network does not work. If I want it to work I have to start network manually from terminal with command:
         sudo ifup eth0
then everything works.

This is my short term workaround for the moment ;)
