Nevermind, it's just a WPS lock.
Now, from what I've seen, there are some things to try.
The mdk3 attacks, but they have to be automated. Found a script to do it by repzeroworld: https://forums.hak5.org/index.php?/topic/32494-reaver-ap-rate-limiting-detected-and-automatic-mdk3-solution/
But it's for reaver... I need it working for Bully, as reaver just hangs on the "Association sucessfull" message.
Another thing I wanted to try out was something like a mac changer automated script, to change mac address every x seconds.
But how viable is this option? Don't the interfaces have to be down in order to change the MAC?
If so, that would mean that I would have to automate that too. Stopping the attack on Bully, changing the MAC, and starting the attack again...
Can anyone shed some light on all this?
