    摘要: Instead of scanning all the channels at once, the present method separates a channel scanning procedure into multiple channel scanning operations. The method reduces a data loss rate during the operation by returning to the operating channel an associated access point operates on in accordance with a return period for transceiving blocked packets.

    摘要: The method generates a candidate list in accordance with the contents of frames transmitted by access points and sequentially performs the handshaking operations with the access points on the candidate list to select a personal identification number (PIN) enabled access point. During the candidate list generating process, this method places Wi-Fi protected setup (WPS) PIN-enabled access points at high priority positions but eliminates non-WPS access points and WPS push button configuration enabled access points.

    摘要: In order to obtain information related to operating channels of access points, the method receives lightweight beacons on a common channel. The method generates a channel scanning list in accordance with the content of the lightweight beacons and sequentially scans all the channels on the list. The method is capable of reducing the scanning time and the data loss rate during the scanning operation.

    摘要: A method for progressively scanning channels first checks whether all channel scanning tasks are completed so as to determine a channel that will be scanned first. During the scanning process, the method records a channel as a last scanned channel after completing a channel scanning task for the channel. In addition, the method scans a channel with a valid service set identifier to increase the possibility of detecting hidden access points.
