Comment 3 for bug 579941

Ashutosh, why do you think anything was done through the Network Connections GUI?

To be clear: I did a straightforward install from a KUbuntu Lucid CD, formatting my root partition first. Other than picking my timezone and partitions to format, I picked installer's defaults. The network connection then worked fine for over a week, during which I updated the installed packages at least once. Then a few days ago it stopped working. While trying to fix the problem, I realized that /etc/network/interfaces only contained the definition for loopback, and restored my network access by adding eth0 to this file. I didn't try fixing the problem via the GUI, because I didn't know about it. At any rate, something caused my network configuration to be lost, wherever it is defined by default -- in the GUI or /etc/network/interfaces.
