Abstract
A network device is adapted to be connected to wired and wireless network interface modules for packet transmission therethrough, and includes a network interface selecting module including a connection status monitoring unit and a network interface selecting unit. The connection status monitoring unit transmits an address resolution protocol (ARP) request packet via the wired network interface module for determining a connection status of the wired network interface module through an ARP response packet received by the network device if the network device is configured with a device internet protocol (IP) address and a default IP address belonging to the same subnet, and transmits an internet control message protocol (ICMP) request packet via the wired network interface module for determining the connection status of the wired network interface module through an ICMP response packet received by the network device if otherwise.
