1. A method performed by a Wireless Fidelity (WiFi) station for discovering an access point in a WiFi network, comprising: receiving a scan request designated to trigger the WiFi station to send on a channel in a WiFi network a first probe request to request for network information required by the WiFi Station, the scan request indicating a delay time for postponing sending of the first probe request; listening to the channel during a first preset period of time, the first preset period of time comprising the delay time; upon detecting on the channel during the first preset period of time a second probe request sent by a second WiFi station and comprising a network information identifier corresponding to the network information required by the WiFi station, determining to further postpone sending the first probe request by a second preset period of time, the second preset period of time being set to include a time during which the access point needs to response to the second probe request; detecting a network discovery message from the access point during the second preset period of time; determining that the network discovery message comprises network information required by the WiFi station; and determining to cancel sending the first probe request when the network discovery message comprises the network information required by the WiFi station.
