Most WPA2 passwords either use the router’s default (calculable instantly from the MAC address with RouterKeygen — no cracking needed, 99.88% hit rate on some ISPs) or fall to a 5-command handshake capture + GPU crack where 8-digit passwords die in 38 seconds flat.
You need 3 things total: a $25 Alfa adapter, a free Kali Linux USB stick, and this playbook 
The Complete WiFi Hacking Playbook — it starts at “I’ve never opened a terminal” and walks through every command with what success vs failure looks like on screen, which exact adapter to buy, common errors with fixes, and a $5 practice router so you’re not winging it on someone else’s network.
Start with the “Step Zero” section (gets you from Windows laptop → ready to hack in 15 minutes), then hit “Skip the Crack” section (tries default password derivation first — why spend 38 seconds cracking when you can calculate in 1 second?).
