(The wireless cracking used in this article refers to the cracking of wep, and the cracking of wpa is still a technical problem, which is not discussed in this article. Assuming that your wireless router needs to be encrypted, please also use wpa mode to ensure security. Assuming you don't know what wep and wpa are, please baidu and I'll give you a professional answer. The simplest explanation is the password of the wireless signal, which is more encrypted than the former.)
