An automatic network connection device includes a first connection port, a second connection port, a first network connection unit, a second network connection unit, a control unit, and a switching unit. When the first network connection unit operates normally, the switching unit electrically connects the first network connection unit to the first connection port, such that the first network connection unit transmits and receives a network signal. When the first network connection unit fails, the switching unit switches the first connection port to be electrically connected to the second network connection unit, such that the second network connection unit transmits and receives the network signal.
