As you surmised:
castagna:~# grep -i ieee80211 /boot/config-2.6.14-2-686
# CONFIG_IEEE80211_DEBUG is not set

Nearly! You were right that the modules were not loaded. I tried
'modprobe ieee80211' and 'ifup eth0' and also rebooting after editing
/etc/modules. It now loads two modules ieee80211 and ieee80211_crypt.
I assume that is the expected outcome.
It still does not associate automatically, but if I
manually 'ifconfig eth0 essid...' and 'ifconfig eth0 key...' and then
'ifup eth0', then ifconfig eth0 shows the 'Frequency:' and 'Access Point:'
for the router correctly. But still ifup eth0 fails to get an offer.
(BTW, I tried several iterations, and on one occasion, iwconfig failed 'No
such device' and I then found it had allocated wlan0 instead. That did
connect either. I think this is a red herring [=irrelevant and
I must be getting close. iwconfig now shows, for example:
...Link Quality=18/92 Signal level=-79 dBm Noise level=-97 dBm
Are those reasonable figures?
Thanks for the help so far -- and on xmas day!
