wifi hack

With fluxion or airgedon on wifislax you'll never need to buy a wifi box.
All neighboring access points are yours
 
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.
 
Maybe using kali nethunter on your phone and crack the wifi using aircrackng + hashcat after recovering the pcap file?
