Bat file to connect to the Internet?

Question

cmd/bat

Hi, tell me how to create a bat file for connecting to the Internet (it asks for a login and password) and a bat file for disconnecting from the Internet, I found the commands

cd %systemroot%\system32 
start rasdial [имя_подключения] [имя_пользователя] [пароль]

cd %systemroot%\system32 
start rasdial [имя_подключения] /disconnect

They don't work
