If after connecting to the WiFi network, the device does not automatically open the authorization page or the message "unable to connect, internal error" is displayed, it means an attempt to enter a secure site (mail.ru, vk, etc.), in this case, in the command line of the browser (except Google Chrome) type ya.ru, the welcome authorization page will open.
When reconnecting, if the connection page does not open, type the same site in the browser command line.
