Wireless-tools is 27+28pre10-1. This is the same as in the cache.
libiw27-28pre10-1 - perhaps this is the problem? It does not seem to be
installed. dpkg -s shows that libiw27 is "purge".
It is present in the cache but running dpkg -i on this did not alter the
situation; it still appears as purged. libiw-dev is also not there.
According to the log, wireless-tools and libiw were both upgraded on 19
October. The connection was certainly working after that.
I'm beginning to think about reinstalling, since I have enough spare
space on the disk so I would not have to delete anything. But it still
seems like overkill.
