Disabling WPS (Wifi Protection Setup) can be very important since it is just a hard coded numerical number that can be brute forced pretty fast using Reaver https://code.google.com/p/reaver-wps/...

True, but the Reaver hardly depends on the signal conditions you have.
If the routers wifi signal is good then it will be fast.But if its not so good and you still can connect, then it may last more than 1-2 days to crack it >> True Story <<, but still it will even if its WEP, WPA, WPA-2.

Also you can check for the WPS vulnerability doing that :

Code:

airmon-ng start wlan0
wash -i mon0

Every wifi it appears after that is vulnerable on Reaver (WPS).

NOTE : Code I 've shown is for Kali linux, else you must install both Aircrack and Wash suites.
