That's not good. Is your wireless device listed in [1] ? What does
"dmesg" say about this ? Are all modules loaded ?

Here (USB device Netgear MA111), I got these outputs:
$ lsmod | grep 'prism\|p80211'

$ dmesg

That is a Debian specific error, which is OK [2].

I have definitely no idea how this works, perhaps does someone on
linux-wlan-user-request know about this.
