I sent that patch on July 24, or at least I thought I did. I was quite surprised 
to not find it in the wireless archives. In any case, I have sent it again tonight.

I tried Herton's sequence of steps for cennecting and it failed no matter what I 
did. In my case, only NetworkManager can get a connection.

I'm not sure how to proceed; however, if you can produce the problem reliably, 
then you have an edge.
