Yes, according to the logs, NM is aware of your Wi-Fi device and you should be 
able to see available networks simply by left-clicking the nm-applet icon.

You can also list scanned Wi-Fi networks by
nmcli dev wifi
or nm-tool

'nmcli dev status' will show you status of your devices.

The attached nm-applet2-root.png just shows configured connection profile for a 
wireless network.
