Wireless Local Area Network (WLAN'S) has become increasingly more prevalent in recent years. The IEEE 802.11 is one of the most widely adopted standards for broadband wireless internet access. Also, security issues became more complicated in the wireless network than wired network. The default IEEE 802.11 standard has defined some security mechanism for securing access to its network. To enhance the security in IEEE 802.11, IEEE 802.11i has been proposed. It is proven that by using Extensible Authentication Protocol (EAP) IEEE 802.11i support variety of upper layer Authentication methods with different advantages and disadvantages of them itself.
