Michelangelo,

The SSID is hidden. I don't understand (as you mentioned) how I could be connected to both either. Win 10 showed my primary WIFI network to be connected, and the AA hotspot, when I double clicked, indicated, 'Disconnect?', which I interpreted as a connection as well.

I will attempt the test you described later on today (move the unit near the router, first connect via ethernet, enter the wifi credentials, and then disconnect the cabe).
