Comment 1 for bug 495319

I have a similar problem on Ubuntu Karmic (Wicd 1.6.1).
At booting time, about one time out of two, either with the wireless or the Ethernet network, after a certain amount of time trying to obtain an IP address, I have the message "Connection failed:Unable to get IP adress".
It also occurs when I unplug my Ethernet wire and plug it again on another port. Getting the IP address takes a very long time. Sometimes, I reboot, because it is faster.
