Abstract: PROBLEM TO BE SOLVED: To provide a control method for a wireless LAN module for efficiently exchanging data. SOLUTION: First of all, it is decided whether or not a power source for supplying power is an AC adapter (step S201). When the power source is the AC adapter, data are exchanged (step S206). When the power source is not the AC adapter, on the other hand, the state of a link with an access point is measured (step S202) and further, when a radio wave strength is lower than a threshold as a result of measurement, a channel search is carried out (step S204) so that data are transmitted/received to a new access point (steps S205 and S206). In such a control method, when the power source is the AC adapter, data can be continuously exchanged without measuring the link state or carrying out the channel search.

Abstract: PROBLEM TO BE SOLVED: To provide a system in which security can be strengthened in a wireless LAN. SOLUTION: In a network security system, clients 10a-10e are connected to the LAN by radio transmission to search nearby access points (AP). The list of the acquired access points as a result of the search is sent to a controller 20. In the controller 20, the list of access points registered beforehand is compared with the lists sent from the respective clients 10a-10e and detects unregistered access points.
