These days wireless network devices (smartphones, tablet PC, laptop) are being utilized more frequently. In line with the increasing number of users of a wireless network, the usage of wireless access points is also increasing. Nowadays as nationwide wireless network services being made available, wireless networks are increasingly being used due to the lower costs of building faster and affordable private or carrier networks. However wireless security is not keeping up with this development. Many use open networks where anyone can join, meanwhile for those using wireless security protocols there is the problem of managing the password. In this paper, we analyze the problems of trying to build a user authentication system using an access point and the RADIUS server.
