Arduino Yun Mini and javascript

Hardware Arduino Yún
4

I just guess what is problem.

  1. My Arduino Yun Mini use IP from Smartphone Wifi tethering. So, it is impossible to communicate with javascript..

or 2) Should I have to put this html file into SD card? There is no SD card slot in the Arduino Yun Mini

I thought that when I know the IP address and port of Arduino Yun Mini, i can communicate with arduino yun mini everywhere. But it is impossible to access with other desktop even with REST. >:(
