1. A method for controlling bandwidth of a channel including a plurality of subchannels by an access point, comprising:
acquiring first wireless status indication for the channel without scanning the plurality of subchannels of the channel;
determining whether the channel is abnormal based on the first wireless status indication for the channel;
scanning the plurality of subchannels to acquire second wireless status indication for each of the plurality of subchannels if the channel is determined to be abnormal;
determining one or more subchannels in the plurality of subchannels to be abnormal based on the second wireless status indication for each of the plurality of subchannels; and
puncturing the one or more subchannels determined to be abnormal;
determining whether one or more subchannels in the plurality of subchannels are punctured if the channel is determined not to be abnormal;
scanning the punctured one or more subchannels to acquire third wireless status indication for each of the punctured one or more subchannels if one or more subchannels are determined to be punctured; and
depuncturing the punctured subchannel that is determined to be normal based on third wireless status indication therefor.
