Nighthawk RAX120 WiFi radio(s) not starting

So, I leave town and after one day my WiFi cameras at home go offline (not connected to WiFi). Upon return, I find the AX6000 Router has a steady power LED on, and a flashing Internet LED on, and no other LEDs lit. After multiple power-offs and checking all connections, the router will only display the same as above. I also noticed that it appears the cooling fan is not turning.

So, is it a dead unit? No other electronics are harmed, and the cable WiFi is working just fine.

Thanks for any feedback!
