That indicates "no connection".

Which indicates that NM is trying to connect to a wired connection.

NM negotiating to join a WiFi network.

Somehow NM is convinced that it should try an Ethernet connection
first. You need a way to disabuse it of that notion.
What does your /etc/network/interfaces file look like? Is your Ethernet
device present there? If so, try commenting it out and restarting NM.
Otherwise, as Brad Rogers <brad@fineby.me.uk> mentioned,
