Usually people won't tell you, so you have to crack the wireless network password.

Cracking needs to be bought outside the software, which is the CD version of backtracking 3.

BT is a linux system that integrates many cracking software, and the current version is 4.0.

This software can be downloaded from the website or bought on CD.

At present, only WEP type can be cracked

WPA can't be cracked, of course it can be cracked in theory, and so can 100.

If you want to crack more and further, you need a receiver. For example, the price of Alfa King Yellow Card is around 80-300. Everything is fine. I bought it.
