Abstract
A wireless communication device can be wirelessly connected uniquely to a specific single wireless communication access point among a plurality of these access points in a roaming environment. Wireless LAN terminals input a connection ID for identifying a specific access point among access points and transmit the entered connection ID to one access point that has been wirelessly connected. If a frequency channel for making a connection to a specific access point corresponding to the connection ID is designated by a notification, from the wirelessly connected one access point, indicating whether the connection ID is appropriate or not, then the wireless LAN terminals set this frequency channel and establish a wireless connection to the specific access point.
