[  247.258497] type=1400 audit(1389974945.608:41): apparmor="DENIED"
operation="connect"
profile="/usr/lib/NetworkManager/nm-dhcp-client.action"
name="/run/dbus/system_bus_socket" pid=3048 comm="nm-dhcp-client."
requested_mask="r" denied_mask="r" fsuid=0 ouid=0

Volker says neither wired or wireless work.
