HACKING WPA2(the Fastest Way) NO WORDLIST and WPS BRUTEFORCING

I have tried hacking wifi with the following tools and they did not work:

1-aircrack-it took a lot of time and still did not work,i think because the the ap was turned off in the middle since where i live there is a shortage of electricity

2-reaver-it gave me an error code 0x3 or something

3-Bruteforcing- it takes too long

So i would appreciate if anyone could help me with this, i know i can use social engineering tools such as Wifiphisher or Fluxion but i wana find out some other way to do this, i assume that there must be faster ways of doing this which are used by actual hacker, so if anyone can help me it would be much appreciated.
