Wireless LAN device

A wireless LAN device that can be wired to a first network device, wirelessly connected to a second network device, and adapted to relay communications between the first network device and the second network device, comprising:

• a wired communication section for communicating with the first network device;
• a wireless communication section for communicating with the second network device;
• and
• a controller for controlling the operation of the wireless LAN device so that the wireless LAN device operates as an access point or a client in a wireless LAN;
• wherein the controller includes:
• a packet transmission controller that has a function of transmitting a DHCPDISCOVER packet from the wired communication section to the first network device at prescribed timing and a function of transmitting a Probe Request packet from the wireless communication section to the second network device at prescribed timing;
• a first operation controller that can control the operation of the wireless LAN device so that the wireless LAN device can operate as the access point when the wired communication section receives a DCHPOFFER packet from the first network device in response to the DHCPDISCOVER packet;
• and
• a second operation controller that can control the operation of the wireless LAN device so that the wireless LAN device can operate as the client when the wireless communication section receives a Probe Response packet from the second network device in response to the Probe Request packet.
