Abstract
Access point 20 starts the WEP key setting process by working registration button 127A of remote controller 30. The range reached by the electric waves transmitted from access point 20 is changed from wireless communication area AR1 which is the normal range to security communication area MR1 which is a narrower range. After that, access point 20 delivers the used WEP key to terminal 50, and after confirming delivery, registers the MAC address of terminal 50. Terminal 50 sets the delivered WEP key itself.As a result, it is possible to realize with a simple method the new addition of terminals used for a wireless LAN while preventing leaking of data that represents the encryption key.
