Abstract: A wireless signal extending method is disclosed. A link between an electronic device and a first network node access point (AP) is generated. The electronic device connects to the first network node AP according to backhaul information. It is determined whether a location where the quality of connection signals with the first network node AP meets a preset value is discovered. If a first location where the quality of connection signals with the first network node AP meets the preset value is discovered, a second network node AP is placed at the first location. The second network node AP is enabled to enter in a pairing mode. A push button configuration (PBC) function of the first network node AP is remotely triggered to automatically pair the first network node AP and the second network node AP.
