I got a strange one too...
After doing an apt-get update && apt-get dist-upgrade
reaver v1.4 finally worked fine for me.
Then when adding the new repositories as per the blogpost and
updating again, same story as before, no association. lols.. driving me mad..
Ah, seems to work great with the VMware version of BT5 R2, will do a fresh install on netbook and check again.
YAY ! Everything works great on netbook too with a nice fresh install
