PROBLEM TO BE SOLVED: To provide a communication device that can more flexibly determine a network interface that will be made effective in a case where either interface is exclusively switched on and used in a communication device having wired LAN and wireless LAN functions.SOLUTION: A communication device can switch and use a plurality of communication functions, wired LAN and wireless LAN functions. The communication device comprises: a network interface control means 2 which makes a wired LAN or wireless LAN effective or non-effective; wired LAN communication propriety acquisition means 3 which can detect that a change has occurred in the communication propriety state of the wired LAN, and acquire a communication propriety state; and network interface determination means 1 which only makes one network interface effective on the basis of the communication propriety state of the wired LAN acquired by the wired LAN communication propriety acquisition means 3 and a plurality of conditions the device has. |
