Got it, I understand what you mean now.
Unfortunately, the configuration is not "reset" if you delete all
available connections, you'll likely want to go back to nm-applet and
click on the wired device (a connection in nm-applet named "Auto
ethernet" or something like it) to allow it to connect, which should
create a new DHCP configuration.
In other words, after cancelling connections, when there is nothing
listed in the Connection Editor, you'll want to go back to nm-applet and
click on the "automatic" entry that should be there (you may need to
disconnect and reconnect the cable for it to appear).
As far as I can tell, this properly handles the cases where someone
deleted all the configurations, and allows one to recover from the
customized connections being deleted. "no-auto-default" is required to
avoid re-creating a default connection which would be automatically
tried when a cable is connected.
Still, there doesn't seem to be a bug here, so I'm setting this back to
Invalid.

Title:
Network Manager does not connect the network adapter to a network with
a DHCP server automatically
Status in “network-manager” package in Ubuntu:
Invalid
Bug description:
When I insert a network cable into my ethernet port, network manager does not
automatically assign an IP to my network device eth0:
I was carrying out laptop testing on Networking - Cabled in Ubuntu Desktop
amd64 for Quantal Beta 2
(http://laptop.qa.ubuntu.com/qatracker/milestones/239/builds/24437/testcases/894/results),
I disabled wireless networking in Network Manager, inserted a network cable
into my ethernet port, but no IP address is assigned to eth0.
I had to open terminal and insert this command:
sudo ifconfig eth0 192.168.17.30 up
only after this did my wired network start working.
This is my hardware:
