I do not think you necessarily have any miscoconceptions and, if you
have, I am not the one to disabuse you of them. My laptop's wireless
is managed by ifupdown and wpa_supplicant. Switching off the wireless
access point and switching it on again sees the laptop reconnect to
the access point. It could be ifplugd is involved in the process but
I have not examined the fine details of my setup to find out.

OTOH, the wireless sometimes drops out without my intervention. Then
I have to resort to ejecting and reserting the PCMCIA card to get it
going again. One day (I say to myself) I'll work out what is happening.

I see WiFi as akin to magic. All those elecromagnetic waves bouncing
of many walls and doors and even penetrating them when they shouldn't.
While I prefer ethernet connections I can live with wireless if it
behaves itself :).

wicd is fine but it utterly dependent on the supplicant. Now I am
thinking how to adapt my setup (if necessary) to do the same as the
wicd-curses daemon.
