OK, it's not there.  No big surprise, since it's clearly USB: 

How about "lsusb"?

wlan0 is obviously not a valid wireless interface - but is that what it was
called when it _did_ work?  Different drivers may use different interface
names. When you unplug the USB connection, are the p80211 and prism2_usb
modules unloaded (ie, do they disappear from "lsmod")?    If not,
try "rmmod p80211; rmmod prism2_usb", until you get them to unload.  Then
plug in the connection and see if it makes any difference (I find one
interface always comes up correctly only after I hibernate & resume,
because that forces this removal/reload and makes sure that the wireless
drivers are loaded in the correct order).

What does that mean?  "Connection information clicked" where?
