92.8% and doesn't want to go further since 24hrs

[GoogleCodeExporter]

I have alfa awus036h with backtrack 5r1 and i installed new compat drivers.
I chose network and my speed varied from 3-30sec/pin but after 8min reaver 
skipped to 92.8% and can't go further since 24hrs.
I tried -a -N -L -S -d 0 --win7 but none combination works.
Whatever I choose it is always showing me:

[+] Trying pin 01702002
[+] Sending EAPOL START request
[+] Received identity request
[+] Sending identity response
[!] WARNING: Receive timeout occurred
[+] Sending WSC NACK
[!] WPS transaction failed (code: 0x02), re-trying last pin
[+] Trying pin 01702002

by the way. I run multiple terminals with reavers. Yesterday I troed 6 
instances and only 2 worked, others were stopping. Is there a limit or 
something or is it coincidence?
