I just got the Optic Fiber with a modem but don't have Internet when I plug my new ASUS RT-AC68U router in between. I managed to install Advanced Tomato on the router and absolutely love it, but no Internet connection. (Before that I had a cable connection and an ASUS RT-N16 with Tomato Shibby, it worked perfectly.) I suppose I have to modify some settings in Advanced Tomato to make it work with the Optic Fiber and the ISP modem/router, but I don't have any idea on what to do. Is anyone familiar with this topic and could help me to figure it out please ?
