I've got an Asus N66U router. Recently it has been going out (meaning I can connect to the router but can't reach the internet), so I'm trying to access the settings page at 192.168.1.1. When I do, I get a webpage that says Broadcom CFE Miniweb server which is asking for a file to flash the router. I've never flashed the router before, and am using stock Asus firmware. Does anyone know what's going on?
