connection type

Hi, recently i did a project using javascript, and one of job is to get the
connected network type. I use the function of navigator.connection.type but
it didn't work, i wonder should i change some configuration or what other
problems? could u tell me and update the website to instruct other reader,
thank you


Best wishes!
