The invention provides an automatic configuration server redirection method and automatic configuration servers. The method comprises the following steps: firstly, a first automatic configuration server receives a notice from an FAP, wherein the notice is used for indicating a change of the connection relation between the FAP and the access gateway; secondly, the first automatic configuration server selects a second automatic configuration server to be connected according to the preset strategy and the status information of all the automatic configuration servers in the wireless network environment, wherein the status information is stored locally; and thirdly, the first automatic configuration server transmits a redirection message carrying the parameter information of the second automatic configuration server to the FAP, wherein the redirection message is used for indicating that the FAP is connected to the second automatic configuration server. The technical scheme of the invention can optimize automatically and enhance the utilization ratio of the system resources, thereby enhancing the system capacity and the system utilization.
