I'm trying to connect my new Asus RT-AC68U to my Bandluxe R500 4g modem/router that I've been using for a few months. I enabled DHCP on the Asus router and disabled it on the modem, I also tried it the other way around, and nothing. I can't get the router to establish an address. The modem works fine when I plug my pc directly into it though. The IP of the modem and router are 192.168.1.1 and 192.168.1.2 respectively. Everything else is set to automatic. What am I doing wrong?
