As of now, for no reason I can see, the dropouts have stopped. I have neither changed my WPA and ifupdown configuration nor upgraded directly related packages; but still, the problem is gone. I assume this is due to some package update that seems unrelated, but somehow isn't, like avahi-autoipd or dhclient3. Who knows?
With the maintainers blessing, I'm gonna give it another week or two and if the problem stays gone, I'm gonna close this bug. If you insist on closing it now, fine, but don't be surprised by a reopen if the problem returns. :-) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
