My scenario is that I (mistakenly) clicked on a wireless network (a neighbor of
mine) that I do not have access to. Since I cannot find a way to disconnect or
remove the auto-connect for that network, periodically I get dialogs in my face
telling me to enter the authentication key (which I don't have).

This seems as a design flaw, or am I missing something?
