I was using the Desktop Beta version of Feisty, but I have got the same behavior, even the translation in pt-br says it is disconnected when it is clearly connected.
After the last # apt-get upgrade even the icon had the red X indicating the disconnection, but I had IP and I was able to navigate fine.
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
