(S41b), the assigned public address IP address is set as the public IP address of the access point 111 (S41c). Then, the IP converter 119 converts the public IP address assigned to the access point 111 into a private IP address and assigns it to the user terminal (S42).

Then, the access point 111 accesses the wired Internet network through the Ethernet interface 114 according to the DHCP method (S60c).

When the access point 111 is connected to the wired Internet network through the Ethernet interface 114 according to the DHCP method, the access point 111 is assigned a public IP address assigned through the Ethernet interface 114 (S61b) and assigns it. The set common address IP address is set as the common IP address of the access point 111 (S61b). Then, the IP converter 119 converts the public IP address assigned to the access point 111 into a private IP address and assigns it to the user terminal (S62).
