(The wireless cracking in this article refers to the cracking of wep. The cracking of wpa is still a technical problem and is not included in the comments of this article. Assuming that your wireless router needs to be encrypted, please use the 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.)
