The present invention relates to a method for automatically re-connecting customer premises equipment (CPE) web user interfaces (UIs), capable of continuously sending a login request to a HTTP server to reduce the time for the user to wait, the method comprising: inserting a frame into a web page in a system to be re-connected and logged in; requesting a HTTP server to send a new web page through the frame after a customer premises equipment (CPE) completes software update and receives a response requesting the system to reboot; issuing a re-login request if the new web page is received, indicating the HTTP server has been started up and a new connection is made; and logging in the system.
