You took the words right out of my mouth, thats exactly what I was thinking. I actually had 3 ideas.
1: Trigger PBC
2: Trigger AP to accept a client's WPS pin
3: Send an M8 packet to attempt to reconfigure the AP
I'm not so sure that any of these ideas will work since I'm no super hacker or programmer, but it is just something I see possible
