On Ubuntu the maintainers modified NM to not manage devices that are
configured in /etc/network/interfaces.  Since you can connect to one
network I suspect it is configured there.  If you use the Ubuntu
networking tools and set the interface to disabled and restart
networking (or reboot) nm should manage your network cards again.
