I have a kiosk running on Ubuntu Server 14.04.3 which currently accepts a LAN cable as an internet source.
What I want to do is to let it receive internet also from a 3G USB (netstick). I started looking around the web for that and it seems that I need to know exactly which Internet provider is it and the modem. Unfortunately I can't know that since anyone may come and connect their own netstick. I was looking for a way to simply accept all netsticks regardless of the Internet provider etc.
Is it possible that whenever I connect a netstick to the computer it will be auto detected and I will have Internet connection while not knowing ahead of time what netstick I'm going to plug in?
