(In the new era of the continuous development of wireless communication technology, wireless LAN has become a hot topic in the computer Internet industry. However, the security of WLAN is not strong enough, which has hindered its further development and has always affected its development. In the process of wireless LAN gradually being widely used, it also puts forward higher requirements for its security. WLAN breaks through the limitations of traditional wired network, but there are also many security problems. Therefore, we must strengthen the awareness of WLAN security and actively explore WLAN security solutions, so as to effectively ensure the smooth development of WLAN business. Combined with the current development situation of WLAN, this paper focuses on the security solutions of WLAN.)
