Wireless local area network access method, access point and terminal

The invention provides a wireless local area network access method, an access point and a terminal. The method is characterized in that a notification message sent by AP on a channel of a first frequency band carries channel information of the first frequency band and also carries channel information of a second frequency range which expects the terminal to preferentially access so that the terminal can rapidly acquire and maintain channel information of the plurality of frequency bands; and then when the AP is subsequently accessed, according to a predetermined strategy, in the channel information of the plurality of maintained frequency bands, the frequency band of priority access is directly selected to carry out access. High-efficient and rapid frequency spectrum navigation is realized, several times of repeated overtime processes or disassociation operation in the prior art are avoided, frequency spectrum navigation time and channel occupation are reduced and a user experience is improved.
