Need Help with Aircrack-Ng

Hi there I have recently posted a forum on how I needed help on installing kali Linux on a virtual machine, and I have successfully installed it, I would like to give a big thanks to these guys:

Ciuffy, Ragin' Hacktivist, CyberHitchHiker. These guys are awesome be sure to follow them for amazing feedback for solutions and also their content.

But this time I need help with another situation, so now that I have installed kali Linux I was trying to crack my own wifi (for educational purposes only) and finding out that I need a "password list?" I am not sure where and how to get this but from where I am from passwords for modems are 10 characters long and consists of letters and numbers, the letter can be lower and upper case but no symbols or special characters whatsoever.

Any response would be appreciated thanks!
