A wireless communication system includes a terminal device; a first wireless communication device; and a second wireless communication device. When the first wireless communication device communicates with the second wireless communication device by wireless LAN communication after a handover and completes prescribed processing to the second wireless communication device, the first wireless communication device sends first disconnection information to the second wireless communication device to disconnect the second wireless communication device. The second wireless communication device stores wireless LAN connection information before communicating with the first wireless communication device by the wireless LAN communication when the second wireless communication device is connected with the terminal device at a time of the handover. The second wireless communication device disconnects the first wireless communication device and connects with the terminal device based on the wireless LAN connection information when the first disconnection information is received.
