1. A wireless communication device comprising:
a communication unit;
a storage unit that stores switching destination information indicating correspondence between a travel route of the wireless communication device and a candidate switching destination access point, wherein
in the switching destination information, a connected access point at a certain time point is associated with a previously connected access point at the certain time point and a switching destination access point; and
a control unit that:
monitors strength of a radio signal transmitted by a currently-connected access point at a current time point,
retrieves the switching destination information from the storage unit, and upon determining that the currently-connected access point and an access point connected immediately before the current time point respectively match the connected access point at the certain time point and the previously connected access point at the certain time in the switching destination information, identifies the switching destination access point in the switching destination information as a connection destination access point, and
execute connection processing to the connection destination access point that has been identified in response to the strength of the radio signal transmitted by the currently-connected access point falling outside a threshold value.
