Your best bet would be to use linux with a hacking distro (i prefer kali over parrot).
Then you wanna tools like
airmon-ng (capture WP2 handshakes)
aircrack-ng to crack wordlist using CPU
hashcat if you wanna use ur GPU if you have a good one.
wifite (captures handshakes and deauths & uses its pre-built word list)
rockyou.txt has a good basic wordlist
Best option is to re-search router before building your wordlist.
