A method for a device to access a network, comprising: generating, by an access point, a broadcast frame, wherein the broadcast frame comprises feature information of a network access device; and the feature information is used for indicating a feature of the network access device; and broadcasting, by the access point, the broadcast frame, so that a specific network access device initiates a network access procedure to the access point, wherein the specific network access device is a network access device which receives the broadcast frame and has the feature indicated by the feature information; wherein: the feature information is specifically used for indicating a feature of identity information of the network access device; the specific network access device is specifically a network access device which receives the broadcast frame and of which identity information contains the feature indicated by the feature information; the identity information of the network access device is a media access control MAC address of the network access device; the feature indicated by the feature information is that: a value of one specific bit in the MAC address of the network access device is a value indicated by the feature information, or values of multiple specific bits in the MAC address of the network access device are values indicated by the feature information; or a result value obtained by performing a specific operation on a value of one specific bit in the MAC address of the network access device is a value indicated by the feature information, or result values obtained by performing a specific operation on values of multiple specific bits in the MAC address of the network access device are values indicated by the feature information; and the one specific bit or the multiple specific bits in the MAC address of the network access device is specified in the feature information. generating, by an access point, a broadcast frame, wherein the broadcast frame comprises feature information of a network access device;
