(The wireless cracking 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 use the wpa mode for safety and security. Assuming you don't know what wep and wpa are, please Baidu and you will get a professional answer. The simplest explanation is the password of the wireless signal, which is more encrypted than the former.)
