I have a Samsung Galaxy S 4G mini (GT-I8190) and I know I have the hotspot feature built-in which transforms my phone into a modem. I have used it plenty of times to tether my phone to other devices (tablet, laptop, etc).
I have discovered recently that it is possible to do a Reverse Tethering and plug the phone to the computer via the USB and get data running on the phone from the PC.
Now, I am interested to combine the two - in order to transform my phone into a real router. I tried to enable the hotspot while getting data from the PC. The phone has access to the internet. And my tablet was able to join the hotspot Wi-Fi network - but it has no network access.
Can anyone shed some light on:
- How USB-tunneling works as far as transmitting the data from the PC? All I know is that it forwards data from a certain port on the PC. I tried to find an "open code source" for the USB Tunneling app but could not. I wanted to have a look on how they manage the data.
- How does the built-in hotspot feature functions? Does it only forwards the Mobile Data to the Wi-Fi? Can anyone share/direct me where to find an open code source for a tethering app? (the built-in hotspot works perfectly - but all downloaded tethering apps fail to run on my I8190).
- I tried to find a tutorial, app, or anything that can explain on how to Wi-Fi tether a Reversed Tethered data without great success. Can anyone help?
