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. -- Brian.
