A drop Prices of wireless LAN equipment has promoted its diffusion in various areas including business enterprises, households and in the public domain. However, unlike the mobile phone network that develops under the management of mobile carriers, wireless LAN is under the independent management of a large number of LAN carriers. Consequently, the terminal setup for connection varies between access points and the users are required to set up their terminals according to the type of access point. Although the emergence of roaming carriers has changed the situation with some access points in the public domain by improving the ease of connection with the use of dedicated software, this improvement is still not available widely, such as for intra-corporate and household networks. In this paper, we describe the features and functions of wireless LAN access permission control middleware that allows users to setup the terminals using the same framework regardless of the control systems of access points. This middleware can also determine the possibility of terminal setup information downloading and restrict the downloaded information according to the personal information of the users.
