Method for connecting network access device to wireless network access point, network access device, and application server

Abstract

A method for connecting a network access device to a wireless network access point includes: initiating an access request to a wireless network access point, wherein when detecting that the network access device is not authenticated, the wireless network access point redirects the access request to an authentication portal, the access request carrying an authentication server address; obtaining, by an application client on the network access device, an authentication parameter after obtaining authentication authorization of a user on the authentication portal; encrypting the authentication parameter by using a wireless access key; initiating, according to the authentication server address, an authentication request carrying the encrypted authentication parameter to an authentication server; receiving the login address and the encrypted signature from the authentication server; accessing the login address on the authentication server; and connecting to the wireless network access point to access the Internet according to a pass-through result.
