Router randomly stopped broadcasting SSID. Now I can't connect

My wireless network was working fine as of last night. This morning I couldn't connect. For some reason my router isn't broadcasting a SSID anymore. Tried restarting computer, powering router off and on, and also resetting the router. None of that worked. I cannot connect to the router's default ip of 192.168.1.1 either.

My router is an Asus RT-AC66U. I'm running Windows 7, 64 bit.

Suggestions? Thanks for your help!
