So to be clear, you went from broadband to fiber with the same ISP? I'm having this same issue as far as symptoms go - router connects and generates a WiFi signal but can't actually access internet - but I've only had CL Fiber in my home, never broadband. CL says it's something on the router side, basically blaming ASUS, and ASUS has been no help.
