1) Till now no one found any method to break that security system, may be in my later posts I will try to post how to break that security system
2) Wpa And Wpa2 Networks can only be hacked using wordlist, Which uses Brute Force Attack Or Dictionary Attack in which probability of getting password is only 35%
3) But In Reaver Method Probability is 100% (Only If AP Rate Limiting Is Not Available)
4) So it is better to go for reaver method if wps is available
5) It consumes less time than Brute Force Attack Or Dictionary Attack
6) If the network that you want to hack has excellent signal and if your system is in good condition, then the hack completes in 5 – 18 Hours.
