Nighthawk RAX54 Not Broadcasting Wifi

Router's 2.4 and 5 GHz lights went out today suddenly. The power, internet, and wifi lights are solid white but the router isn't broadcasting any signal. I tried using the Nighthawk app to see if I'm missing a firmware update but the app couldn't find the router since it isn't broadcasting. I've tried a factory reset and the problem persists. What can I do?

Have you checked to see if the Wi-Fi on/off switch was accidentally pressed?  The Wi-Fi indicator LED is a combination indicator and switch.  A restart or reset does not change the status of this switch.

I double-checked the wifi switch by pressing it on and off and that doesn't seem to be the issue since the wifi LED is on. I've tried using an ethernet cable to connect the router to an external device and the external device isn't getting an ethernet signal either.
