Asus RT-N66U Wifi Issues-WIFI is Dead

[Parag]

All of sudden my Asus router both wifi stopped working. On router I am not able to see any lights for both wifi. Even these lights are not coming up after doing Reset couple of times using different method recommended.
Router is having latest Merlin firmware.
Can someone guide how to resolve this issue?

Try re-flashing the firmware , if that doesn't help it is a hardware failure, time for a new router. Merlin is no longer supporting the RT-N66U apart from security updates.

Thanks for your feedback. I want to use this router without wifi to connect to other devices through lan. but asus firmware is not allowing me to login through UI ...its disabled

Are you sure you're using the correct login credentials, or the UI simply won't come up in your browser? are you using the router's IP address in the address bar of your browser (192.168.1.1, possibly?) or router.asus.com?
