Going very slowly while bruteforcing for last 4 digits.

Hi Fellas,

Not sure if this has been answered before. Couldn't fetch it on google though.

I'm a begginer both in linux kali and reaver. I have downloaded the latest kali 
version and sent the image to my flashdrive. Now everytime I reboot everything 
is fresh (nothing is saved on the flashdrive).
After booting, I'll connect to my network, apt-get update and apt-get install 
reaver, disconnect, start monitoring mode mon0 on my wlan0, and then use reaver.

Then I'll use:
reaver -i mon0 -b my:mac:id -vv -p XXXX
The signal is strong, it's a Belkin.
As you can see, I already know the first 4 numbers because of previous attemps 
on other boots (I made something wrong and my wlan0 stop working at all, so I 
rebooted, but at that point I already had the first 4 digits).
The problem is now, after have found the first 4 digits, everything is going 
VERY SLOWLY: it gets stuck in a single PIN before proceeding. The first half 
brute force went ok, with only a few error now and then (normal).

This is what I get on the second half, mostly:
[+] Trying pin XXXXYZMK
[+] 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

And it repeats alot until going to the next PIN, getting sometimes the WARNING 
10 failed connections error, and sometimes 0x03.
I'm on 93% now, but will take a lot of hours to finish is the correct PIN is on 
the last 1 or 0.5%

I have tried -S,
-f
-d 0
-d 30:30 (don't think this is right)
-S -d 0
-S -d 0 -f

PS: I have already successfully cracked a password from another router of 
mine(other brand) previously, and everything went alright. The only difference 
is that at this time I wasn't apt-get update/install reaver on boot.

PS2: This is a different issue, but with this version of kali i'm using is it 
possible to find the saved sessions of reaver? Cause they ain't where they're 
supposed to be ~/usr/local/etc/reaver/

Thanks a lot!

avoid use -p, this makes mess the file .wpc in /usr/local/etc/reaver/
you can save session in other place with -s /media/flashusb/session.wpc
so try again with:
reaver -i mon0 -b <mac> -a -S -c 11 -vv -s /media/flashusb/session.wpc
to enter with the first 4 digits, first let save the session with 1%, at this 
point cancel and go edit session.wpc and change first line yours 4 digits. Save 
.wpc and run reaver again. you'll jump %
