6. Please describe what you think the issue is.
   On raspberry pi kali Linux,i use wash to scan available ssids,it shows no ap available in the list.there are some wps available ssids surrounded(confirmed by another computer).
   Then i try to reaver an AP called AAA which mac is 14:75:90:XX:XX:XX 
   I use the command 
           reaver -i mon0 -b 14:75:90:XX:XX:XX -vv -a -n
   it keeps switching channels.then i added "--channel 11" to fix channel,it stays associating for a long time.
   However,when i try to connect AAA via a wrong password with UI wifi manager on the desktop.
   the reaver then associated with the ap starting cracking normally.weired,isnt it?

   On BT5, using the same USB wireless card,the same version of reaver,it works perfectly.

PS,i used a usb hub to make sure the card gets enough power supply.

7. Paste the output from Reaver below.

after i tried to connect AAA with password(no matter right or wrong) on 
desktop, it goes well.
