A network access method is disclosed. The method includes: by an access authenticator, receiving a Discover message sent by a client, returning a response message, and obtaining first configuration information used by the client during authentication, where the Discover message is used to discover the access authenticator; authenticating the client or interacting with an authentication server (AS) to authenticate the client remotely as an agent of the client; and sending a configuration request message to a configuration server to request second configuration information used by the client during a session after the authentication succeeds. A network access system, an access authentication apparatus and a broadband access device are also disclosed. The present invention can assure the stability of authentication.
