The invention discloses a UI operation synchronizing method for network switching of an intelligent TV set, relates to network setting technologies of the intelligent TV set, and solves the problems caused by that an obstruction manner is used to wait for response during network switching in traditional technologies. A state machine is constructed, and the driving state of a bottom-layer network interface card is read according to a linux network protocol stack. A network interface card is positioned in a link layer of the linux network protocol stack. A user calls an interface of an application layer of the linux network protocol stack via a UI operation, the network driving state of the link layer is read, and the state machine makes correct response to the user operation and displays the user operation. The method ensures that the bottom-layer network interface card can be enabled or closed normally, UI operation of the user is smooth and not obstructed, and a better user experience of the intelligent TV set can be obtained.
