Dear Bob,
> $ sudo ifconfig wlan0 up
> $ sudo iw dev wlan0 scan
I have typed:
ifconfig wlan0 down
ifconfig wlan0 up
iwlist wlan0 scanning
(I do not have installed iw)
and it works:
wlan1 Scan completed :

.............................................
But when an interface wlan0 become associated, it refuses scanning.
root@dvouramenna:~# iwlist wlan0 scanning
wlan0 Interface doesn't support scanning : Operation not supported
Is this bug or feature?
MadWifi can scan even when interface is associated.
ipw2200bg can also scan when it is associated.
