Abstract: A wireless LAN communication device is provided for making it possible to set beacons including DTIM information elements not to be synchronous in the case that the timing for generating the beacons including DTIM information elements is the same among access points, so that it is avoidable that only a terminal device under a specific access point among access points using the same channel is subjected to a delay and jitters, while anxiety about mutual interference of the terminal devices is removed in the case of broadcast and multicast service, so that a fair broadcast and multicast service can be received. In the device, a wireless LAN control unit (202) detects beacons of other stations received in a prescribed period of time before the transmission of its own station (200). A beacon analyzing unit (203) analyzes the beacons of the other stations and adjusts transmission intervals of its own DTIM beacon.

Abstract: An access controller not requiring a large amount of resources such as a memory device and not needing to change the list of secure host devices each time the configuration of a network is changed. On receiving a DNS response through an access control section (103) of the access controller (100) a secure host list creating section (104) of the access controller registers the name of the secure host device contained in the DNS response, the IP address, and the IP address of a communication terminal which is a request of the DNS in a secure host list holding section (105) of the access controller (100) when the IP address of the host device contained in the DNS response is the one of the secure host device. The secure host list creating section (104) discards a packet when the communication terminal which is the packet sender is a normal communication terminal and when the packet address is stored in the secure host list holding section (105) and reports nonaccessiblity to the normal communication terminal.
