Thank you, Franco.
Both Hotspot 2.0 and Random are unchecked. I even restarted the computer and there is no change. I still see all wi-fi in range - 19 of them, not including two of mine. ALL of them are neighbors. All of them I have never accessed or added. ALL of them have "Connect Automatically" selected. I cannot uncheck them. Each time I do, it checks the box automatically.
Unfortunately, your first suggestion does not apply because all the networks showing up on my available networks list I've never used. So they don't show up in my Manage networks list.
