According to an embodiment, a wireless communication device includes a memory and one or more hardware processors coupled to the memory. The one or more hardware processors are configured to function as a communication control unit and a determination unit. The communication control unit transmits and receives data to and from a first wireless communication device. The determination unit calculates transmission and reception information based on a transmission and reception result of the data, and variation of received signal intensity of the data, and determines whether to maintain connection to the first wireless device based on the transmission and reception information and the variation. The communication control unit controls communication according to a determination result of the determination unit.
