Science means that I ought to be able to reproduce your results, rather than attributing my problems to the Men in Black. Bill P.S. Regarding those lines in /etc/network/interfaces Okay, so that did the trick, I believe, so far as getting my network to behave normally again. I am puzzled about why it should begin to misbehave, when I have been using those settings since long before TDE and Debian. I believe I set those lines back when I started running Linux, sometime around Kubuntu Hardy Heron 8.04, so about 2006 or 2007, back when I still had direct contact with other human beings. Anyway, so the worst of the issue is solved. It seems that I can go online/offline, back and forth, without my connection getting caught in some limbo then needing to reboot. However, there is yet one glitch. When I tried to use tdenetworkmanager to connect, I can look at all available networks, as usual, and everything behaves as expected. I only needed to re-enter my wifi password, enable my chosen network, etc., but when I go to save the network, I am told that I don't have sufficient permissions. On the other hand, wicd seems to work normally again, so that life can go on, one way or another. I would like to solve this new issue, but if not, at least I can control my network connection.
