I used to connect my computer to the internet using tethering on my IPhone while logged in another on network that I had no internet access (just to others computers). To do that on the IPhone Network connections I unchecked the option "Use default gateway on remote network" (on the tab "IP settings" after click on advanced properties of the connection) so the internet traffic went not through the network connection but through the IPhone network connection.
For my surprise there is no such option anymore one options and this way I can not go to the internet, sohow can I do that on Windows 8.1?
